Different types of cryptocurrencies offer diverse functionalities depending on their unique use cases.Cryptocurrencies enable peer-to-peer transactions in a decentralized manner, offering advantages over traditional financial solutions .Most cryptocurrencies fall into one of five categories<1>: payment cryptocurrencies, infrastructure cryptocurrencies, financial cryptocurrencies, service cryptocurrencies, and media and entertainment cryptocurrencies.
A guide to classifying cryptocurrencies
The cryptocurrency market features thousands of unique projects, each with distinct functionalities and technologies. A large majority of cryptocurrency protocols boast their own digital currencies, such as metaverse tokens for digital experiences and memecoins that foster online communities.
While the crypto industry continually presents new opportunities, the diverse applications of blockchain technology can make navigation challenging. Many cryptocurrencies extend beyond the roles of traditional currency, offering a variety of decentralized services.
Understanding the different sectors within the blockchain ecosystem can be helpful for making more informed decisions when engaging with the Web3 landscape. As you explore these categories, consider how they align with your interests and goals.
Let's delve into the different types of cryptocurrencies available in this rapidly growing landscape.
1. Cryptocurrencies for payment
Cryptocurrencies allow users to store and transact value on a decentralized network, free from centralized intermediaries such as banks or governments. This type of cryptocurrency aims to provide faster, cheaper, and more secure transactions than traditional methods.
These cryptocurrencies create an infrastructure to transfer, record and secure financial transactions between individuals across the world.
Litecoin (LTC) is an example of a payment cryptocurrency. Founder Charlie Lee designed the protocol to be a cheaper and faster alternative to Bitcoin's BTC cryptocurrency.

Store of value
Store of value (SoV) cryptocurrencies are assets intended to retain their value over time relative to fiat currencies. 
They offer several advantages compared to traditional assets such as land or precious metals:
Accessibility and portability: Cryptocurrencies are easily transferable, offering convenience to holders.Reduced storage costs: Cryptocurrency storage generally incurs lower costs than the maintenance of physical assets.Limited supply: Cryptocurrencies like Bitcoin have a fixed supply, which enhances their appeal as stores of value. Bitcoin's 21 million coin cap makes its supply easy to verify.
A popular example of a SoV coin is Bitcoin (BTC) : a peer-to-peer electronic payment system enabling direct online payments without financial institutions.
Many find this crypto asset attractive due to its limited supply of coins and predictable issuance schedule.
Memecoins
Memecoins focus on viral internet trends and pop culture references, primarily serving as digital payment tokens. Popular examples like Dogecoin (DOGE) and Pepe (PEPE) have attracted millions of followers, including celebrities.
Often created as lighthearted social experiments, memecoins generally have limited utility compared to other cryptocurrencies and are seen as a fun contrast to the seriousness of traditional cryptos.
Although primarily speculative, memecoins are also used to tip online creators and foster communities on social media platforms.
Stablecoins are designed to reflect the value of fiat currencies and other assets, such as gold.
They combine the efficiency and portability of blockchain-based cryptocurrencies with price stability mechanisms, making them popular for cross-border remittances and traders looking for less volatile digital assets to invest their capital in.
There are three main types of stablecoins:
Fiat-backed stablecoins : Aim for a 1:1 value peg to their underlying currency, requiring issuers to hold cash or cash equivalents in reserve. Examples include:
Tether (USDT) : The largest stablecoin, pegged to the US dollar.USD Coin (USDC) : Another stablecoin aiming for a 1:1 index with the US dollar.Tether Euro (EURT) : A stablecoin that reflects the price of the euro.
Cryptocurrency-backed stablecoins : Backed by other cryptocurrencies locked in smart contracts , often requiring over-collateralization. Users deposit more crypto than the value of the stablecoins they receive. Examples include:
MakerDAO's DAI : Backed by cryptocurrencies and worth three times the amount of DAI in circulation.LUSD from Liquity : Backed solely by ETH.
Algorithmic stablecoins : Maintain a value index without collateral by using smart contracts to adjust supply based on market demand. Price stability has not always been reliable.
It is important to recognize that stablecoins carry risks, including issuer and operational risks. The collateral backing these tokens could be held by institutions that could become insolvent, and algorithmic stablecoins could fail due to bugs or other issues.

Privacy corners
Privacy coins enhance transaction anonymity by obscuring details about the sender, recipient, and amount spent. They use specialized mechanisms to secure transactions, making them difficult to trace and enabling anonymous transactions on privacy-focused blockchains.
Although each privacy coin has its unique methods, all aim to offer greater privacy than traditional cryptocurrencies.
Popular examples include:
Monero (XMR) : Preserves user anonymity through a type of cryptography called ring signatures.Zcash (ZEC) : A privacy-focused fork of Bitcoin that offers complete anonymity using the Zerocash protocol and a "protected" ledger.
2. Infrastructure cryptocurrencies
Infrastructure cryptocurrencies are tokens that enhance the technology supporting other cryptocurrencies. They are primarily linked to blockchain networks, offering smart contract functionality that allows developers to create self-executing agreements for various applications. 
These projects generally focus on building a foundational layer for application development or improving blockchain efficiency through layer 2 scaling solutions.
Application development
The introduction of smart contracts on the Ethereum blockchain has enabled anyone to create decentralized applications (dApps) for the first time. 
Smart contracts now power virtually all Web3 applications on various major blockchains, benefiting from customization and interoperability. 
The rise of decentralized finance (DeFi) and use cases such as decentralized physical infrastructure networks (DePIN) highlight this trend.
Popular cryptocurrencies associated with application development include:
Ether (ETH) : A decentralized platform for financial services, gaming, and applications.Solana (SOL) : A blockchain designed for scalability, offering faster transaction settlement times.Avalanche (AVAX) : A high-speed layer 1 blockchain for dApps and custom networks.
Scalability
Initially, applications on Ethereum and similar blockchains relied on the main network for transaction processing and data storage. While secure, this approach results in low throughput, leading to high gas costs and slowdowns during peak periods.
As blockchain adoption increases, scalability is essential to improve transaction capacity and reduce costs. 
Various solutions have been developed, including:
Optimistic Rollup : Groups transactions and processes them off-chain to help increase the efficiency of layer 1 platforms like Ethereum, assuming all transactions are valid unless disputed.Zk-Rollup : Uses zero-knowledge proofs to quickly validate transactions, adding extra security and assurance.Data availability service : Preventing slowdowns by reducing pressure on blockchains.
Communication
As Web3 develops, a robust communication infrastructure becomes increasingly important. This includes connecting blockchains with real-world data and facilitating communication between Layer 1 and Layer 2 networks.
Oracles connect real-world data to the blockchain, improving decentralized applications (dApps) and the scalability of Web3. 
They provide vital information, such as financial data and social media feeds, and deliver real-time crypto prices from centralized exchanges like Binance to decentralized exchanges like dYdX and Uniswap .
Examples of blockchain oracles include:
Chainlink (LINK) : connects blockchains to external data sources.Pyth (PYTH) : provides real-time market data to financial dApps across various networks.
With the rapid growth of Web3, the number of blockchains is expanding, and developers are creating custom blockchains called "appchains" to optimize performance.
This complexity necessitates efficient communication between networks. Cross-chain messaging and bridges enable assets and data to move seamlessly between blockchains.
Examples of cross-chain infrastructure tokens include:
Axelar (AXL) : Connects dApps across different blockchains.Celer (CELR) : Focuses on cross-chain interoperability for DeFi, GameFi, NFTs and more.LayerZero (ZRO) : Helps developers create omnichain dApps.
3. Financial cryptocurrencies
Cryptocurrencies offer tools for managing and exchanging assets within the crypto ecosystem. Often linked to DeFi protocols, they offer functionalities similar to traditional finance but in a more transparent and accessible way.
Cryptocurrencies associated with centralized or decentralized exchanges are classified as financial cryptocurrencies. They generally offer lower trading fees and can serve as governance tokens , granting holders voting power over platform operations.
Financial markets
Cryptocurrency financial markets integrate traditional financial services with smart contracts and blockchain technology, creating decentralized exchange services, lending platforms, and cross-chain transfers.
Decentralized exchanges (DEXs) allow users to trade cryptocurrencies directly without relying on traditional order books. Instead, they utilize liquidity pools to facilitate efficient asset swaps. Popular platforms like Uniswap (UNI) and Curve (CRV) incentivize users by rewarding them for providing liquidity, creating a community-driven, decentralized trading environment.
Decentralized currency markets allow users to lend their crypto for rewards or borrow against their holdings without intermediaries. This accessibility means that anyone with internet access can benefit from these services, provided they meet collateral requirements. Examples include Aave (AAVE) and Compound (COMP) , which determine rewards based on supply and demand.
Bridges play a crucial role in connecting different blockchains, enabling the seamless transfer of assets and data between them. For example, a bridge can burn USDC on Ethereum and mint it on Arbitrum , allowing for easy movement between the networks. Notable bridges include Stargate Finance (STG) and Synapse (SYN) .
Asset Management
In traditional finance, asset managers invest capital for institutions or wealthy individuals. DeFi democratizes investment strategies, allowing anyone to optimize their assets through smart contracts.
DeFi platforms streamline various services, helping traders make better informed decisions when using multiple platforms.
Popular types include:
DEX Aggregators: Scan multiple DEXs for better transaction execution.Yield aggregators: Automatically move assets between lending protocols to maximize returns.

Structured/exotic products
DeFi has expanded financial services and introduced innovative products beyond traditional markets, including liquid staking and physical assets (RWAs).
Liquid staking:
One disadvantage of crypto staking is that staked funds are locked and cannot be used for other purposes.
Liquid staking addresses the limitations of locked funds in traditional staking, allowing users to:
Earn staking rewards while retaining access to staked assets.Using "liquid staking tokens" on DeFi platforms for lending, borrowing, and trading.
A popular service is Lido Finance (LDO) , where users can deposit ETH and receive stETH, which functions like normal ETH until they exchange their initial stake.
Real-world assets (RWAs)
refer to real and financial assets that are tokenized for trading on blockchains. This area has attracted the interest of banks and financial institutions, leveraging the transparency and efficiency of blockchain to streamline their services.
RWA projects aim to create digital equivalents of traditional assets, such as:
Real estate contracts.Health records.Financial agreements.
Notable platforms advancing RWA tokenization include:
Avalanche (AVAX) : partners with financial companies to tokenize funds.Centrifuge (CFG) : facilitates credit lines and compliance through blockchain technology.
4. Service cryptocurrencies
Service cryptocurrencies provide tools for using and sharing data on blockchain networks. They leverage the transparency and security of distributed ledgers to improve traditional sectors such as healthcare and energy.
For example, some service cryptocurrencies allow users to create digital identities and link real-world records to the blockchain, while others allow individuals to track and trade their energy production via peer-to-peer networks.
Decentralized Physical Infrastructure (DePIN)
DePIN is transforming how infrastructure services like Wi-Fi and cellular data are delivered. By using blockchain technology, DePIN networks incentivize users to build and maintain their own infrastructure rather than relying on large corporations.
Users can purchase specialized devices to collect and store data, providing hedging and earning crypto rewards. Smart contracts facilitate seamless operations, eliminating the need for centralized control.
File storage
Much of our information is stored online as data, and decentralized file storage projects leverage blockchain technology to secure it while protecting against centralized server failures.
Platforms like Filecoin (FIL) and Storj (STORJ) allow users to store files on decentralized networks, offering increased security and transparency. Users can also contribute their unused storage space and earn native tokens (FIL, STORJ, etc.) to expand network capacity.
Digital resource markets
Web3 projects enable the decentralized exchange of digital resources such as computing power, energy, and data.
Computing power:
Decentralized networks enable global access to the computing power of CPUs and GPUs, which can be used to build Web3 applications, create AI models, or host decentralized services. 
Notable examples include:
Akash (AKT) : an open-source cloud computing marketplace that accelerates the deployment of applications in areas such as blockchain and machine learning.Render (RENDER) : a network connecting users needing GPU power with operators having unoccupied GPU capacity to rent.
Energy
Web (EWT) focuses on improving the efficiency of renewable energy distribution by connecting industry participants and transparently monitoring resource distribution, thereby improving market efficiency.
Data
Several projects are dedicated to the organization and distribution of on-chain and external data.
The Graph (GRT) : Indexes data from various blockchains for easy access and visualization.Ocean Protocol (OCEAN) : Allows users to list and monetize various datasets while preserving ownership and confidentiality.
5. Media and entertainment cryptocurrencies
Media and entertainment cryptocurrencies aim to reward users for creating and engaging with content, games, betting, and social media. For example, Basic Attention Token (BAT) promotes a fair distribution of value between creators and consumers.
These cryptocurrencies also support digital worlds known as "metaverses", accessible via virtual and augmented reality technologies. 
In addition, non-fungible tokens (NFTs) fall into this category, allowing holders to prove ownership of unique digital objects, including game characters and digital art.
Non-fungible tokens (NFTs)
NFTs have gained popularity primarily for digital art, with collections like Bored Ape Yacht Club (BAYC) and Cryptopunks making headlines. However, they extend beyond art, serving as proof of ownership on the blockchain for various items, such as concert tickets, Rolex certificates, subscriptions, and virtual land.
NFTs represent ownership of a work rather than the work itself. Some collections, like BAYC , have associated crypto tokens; for example, Apecoin (APE) allows holders to influence the future of the project, showing another use case for cryptocurrencies beyond payments and storing value.

Metaverse
The metaverse is a shared digital space where users interact and engage in virtual experiences similar to the physical world. Decentraland's MANA token and The Sandbox's SAND token serve as utility tokens, allowing holders to purchase land, interact with user-generated content, and participate in governance.
Emerging trends include investment in virtual real estate, digital fashion, and social experiences that merge gaming, art, and commerce. The metaverse also explores decentralized social networks and innovative content creation.

Play-to-earn games
Blockchain gaming is still in its early stages, with emerging trends demonstrating its potential. The composability of blockchains allows characters and games to interconnect, enabling players to use the same profile across multiple games.
Platforms like Enjin make it easier to manage in-game items, reducing the high costs and fraud associated with virtual goods.
These games reward players for their in-game achievements with assets that may have real-world value.

Introduction to cryptocurrency 🤝
Cryptocurrency, or cryptocurrency, is a type of virtual currency designed to improve financial transparency and inclusivity. Unlike traditional currencies, which are governed, issued, and supported by governments worldwide, cryptocurrencies are stateless and are not backed by any central bank, political party, or individual. 
Cryptocurrencies use concepts from cryptography, mathematics, and computer science to offer a decentralized, peer-to-peer monetary system. This system is based on clearly defined and transparent rules rather than centralized authority and trust.
While some dismiss cryptocurrency as a passing fad, others hail it as a revolutionary breakthrough. 
One thing is clear: the potential of cryptocurrencies to redefine the ways we connect and transact can have a lasting impact on every person's life.
Cryptocurrency explained 🔍
Cryptocurrencies are digital currencies that leverage cryptography, computer science, and economics to create a decentralized and highly secure payment system. These three disciplines work together to ensure the integrity and efficiency of cryptocurrency transactions.
Cryptographic techniques protect crypto transaction data. Computer science preserves the consistency of this data between all participants.Economic incentives encourage everyone to follow the rules for the benefit of the network.
A simple way to grasp the advantages of cryptocurrency and decentralized finance over the traditional financial system is to compare them to physical letters and digital emails.
Sending a transaction through the traditional financial system is similar to sending a physical letter through the postal service. It is generally slow, expensive, and requires multiple intermediaries at each stage of the process to reach its final destination.
In contrast, transferring value with cryptocurrencies is more like sending an email. Depending on the cryptocurrency used, transaction fees can be minimal or even negligible. Payments are also processed in seconds, rather than hours or weeks, and no centralized intermediary is needed to facilitate the transfer. 
This is a significant point, but somewhat abstract to grasp. Cryptocurrency allows individuals to send value directly to each other, without the need for centralized intermediaries like governments or banks. 
This allows individuals to retain greater ownership not only of their finances, but also of their information and privacy.
Some of the largest and most popular cryptocurrencies include Bitcoin , Ethereum , Tether , Solana , and USD Coin .
What cryptocurrencies are not 🚫
Cryptocurrency is often misunderstood. Despite its growing presence in the financial world, many misconceptions still obscure its true nature. 
Common misconceptions include:
Misconception: Only used for criminal purposesTruth: The vast majority of transactions are legitimate. A recent report from Chainalysis shows that less than 0.5% of all cryptocurrency transactions are fraudulent or criminal.Misconception: Completely anonymousTruth: Most cryptocurrency owners are pseudonymous, not anonymous. While transactions on the blockchain are visible, linking them to specific individuals can be extremely difficult.Misconception: Harmful to the environmentTruth: Although some cryptocurrencies, such as Bitcoin, have been criticized for their energy consumption, many new cryptocurrencies are adopting more energy-efficient methods such as proof-of-stake.Misconception: Guaranteed by nothingTruth: Although physical assets or governments do not back cryptocurrencies, their value stems from factors such as limited supply, practical use cases, and the functionality of the underlying technology.Misconception: Operated by banks or governmentsTruth: Cryptocurrencies are decentralized, meaning they operate independently of central authorities like banks or governments.Misconception: All cryptocurrencies are exactly like BitcoinTruth: Not all cryptocurrencies are Bitcoin clones. A large majority of altcoins have unique characteristics, objectives, and technologies, offering a diverse range of use cases.Misconception: The same thing as a blockchainTruth: Blockchain is the digital ledger technology that underpins cryptocurrencies, but it has a wide range of applications beyond just digital currencies.
Few things in the world are so misunderstood and yet so fiercely debated as cryptocurrencies. It's important to dispel the myths and understand the facts.
What can you do with cryptocurrencies? 📝
Cryptocurrencies do not all function in the same way, nor do they all pursue the same objective. Here are some of the uses of the most popular cryptocurrencies currently on the market:
Sending valuables from one country to another — quickly and cheaply.To hold a self-sovereign reserve of value.Buying goods and services peer-to-peer.Funding individuals and charitable causes without censorshipCreate and use decentralized applications.Vote on proposals that shape the future of cryptocurrency.Earn rewards for securing the protocol through staking.Join a cryptocurrency mining pool.Directly support your favorite content creators.Establishing ownership of digital assets.

How does cryptocurrency work? ⚙️
One of the main characteristics of the cryptocurrency market is its decentralization. However, when no one is "responsible" for something as important as the transfer of value between individuals, how can a system function without some kind of oversight?
The solution involves two main components: blockchain technology and a global distributed computer network.
Blockchain technology
Blockchains act as a public ledger, tracking and recording all kinds of information. This is made possible by highly secure and censorship-resistant rules. These rules are coded directly into the protocols and are generally available for anyone in the world to view.
Each participant in the network (called a node) maintains its own copy of the blockchain database and helps the entire network reach a consensus on newly added data before it is validated in the blockchain.
Consensus mechanisms
Rather than relying on a single individual to determine whether information is true or false, blockchains require nodes to collectively approve or reject pending transaction data submitted to the ledger. The community can then assess the facts and collectively agree on approval or rejection.
To learn more about nodes and the important role they play in blockchain networks, see our article What are blockchain nodes and clients?
This process of reaching an agreement between all nodes is known as reaching a "consensus".
Blockchains use various consensus mechanisms , such as proof of work and proof of stake , to achieve this. These mechanisms often include incentives and penalties to encourage honest behavior and discourage malicious activity.
Security and integrity
Blockchains get their name from the way they "chain" together "blocks" of information (such as transaction details) by including information from the previous block in each new block.
The header of each new block contains the hash of the previous block, among other data, serving as a unique fingerprint for that block. This creates an immutable chain that anyone can self-verify.
This process is what makes blockchain ledgers tamper-proof, because changing even a single transaction within a block would radically alter its unique digital fingerprint. Attackers would also need to gain majority control of the network (more than 50% of all staking or mining power) to manipulate the order of new blocks and potentially spend funds twice.
This process of linking blocks and ensuring data integrity is a key aspect of blockchain technology and relies on advanced cryptographic techniques. This is also why these decentralized networks are known as "blockchains".
To learn more about these techniques, you can explore how cryptocurrencies use cryptography .
Given the degree of coordination, the amount and the processing power that this would entail, these attacks have become almost impossible to carry out on widely adopted blockchains like Bitcoin or Ethereum.
How to buy cryptocurrency 🧑‍💻
Just as you don't need to be a mechanic to drive a car, you don't need to be a crypto expert to use cryptocurrency. All you need is an internet connection and a device, such as a smartphone, laptop, tablet, or desktop computer.
Once you have that, you have several options to choose from when deciding to buy crypto :
Step 1: Create an account
Many believe that the safest and easiest way to buy popular cryptocurrencies is to use a cryptocurrency trading platform like Binance.
These platforms function like digital exchanges, allowing you to buy and sell cryptocurrencies directly with other users. When you create an account, the platform automatically sets up a crypto wallet for you, providing a secure place to store your funds.
Step 2: Deposit funds into your account
After creating and complete identity verification (KYC), you can add funds via your preferred payment method. Then, navigate to the "Buy Crypto" section, choose your desired cryptocurrency, and follow the instructions on the screen to complete your crypto purchase.
How to Buy Cryptocurrencies Using Bank Transfer?
To buy cryptocurrencies using a bank transfer on Binance, select the "Bank Transfer" option in the "Buy Crypto" section, follow the instructions to link your bank account, and complete your purchase.
How to Buy Cryptocurrencies with a Credit Card?
On Binance, you can buy cryptocurrencies using a credit card by selecting the "Credit/Debit Card" option in the "Buy Crypto" section. Next, enter your card details, choose your coin, and complete the transaction in minutes.

Key takeaways 🔑
Cryptocurrency is a digital currency that uses cryptography, computer science, and economic principles to establish a decentralized and secure financial system.Cryptocurrency uses blockchain technology, a decentralized ledger that securely records transactions.Securing your cryptocurrency involves choosing the right type of wallet and practicing good security habits to protect your assets.

Since the emergence of Bitcoin in 2009, blockchain has become one of the most discussed technological concepts in the world. Yet, despite its growing popularity, it remains poorly understood. Many associate it solely with cryptocurrencies, whereas in reality, blockchain is a much broader technology, capable of transforming numerous sectors beyond finance.
In this article, we will explore in depth what blockchain is, how it works, its fundamental characteristics, its different types, its consensus mechanisms, its practical applications, its advantages, its limitations, and its future prospects.

1. What is blockchain?
The word blockchain literally means chain of blocks. It is a shared digital ledger, distributed across a network of computers, that records information securely, transparently, and immutably.
In concrete terms, a blockchain is:
A ledger that stores dataDistributed (replicated across many computers)Secured by cryptographyOrganized into interconnected blocks
Each block contains:
A set of transactions or dataA timestampA cryptographic reference to the previous block (via a hash)
This structure creates a chronological and tamper-proof chain.
2. How does the blockchain work?
a) The principle of the distributed ledger
Unlike traditional systems where a database is centralized (for example, in a bank), the blockchain relies on a distributed network.
This means that:
There is no single central serverEach participant (called a node) has a copy of the ledgerAll nodes must agree on the state of the ledger
This architecture eliminates the need for a trusted intermediary.
b) Blocks and the hash
Each block contains a set of validated transactions. Once filled, the block is added to the chain.
The link between blocks is based on a cryptographic function called a hash.
A hash is:
A unique digital fingerprintGenerated from the data in the blockImpossible to reverseExtremely sensitive to changes
If data in a block is modified, its hash changes. This automatically invalidates all subsequent blocks. This property guarantees the integrity of the chain.
c) Transaction Validation
For a block to be added, transactions must be validated by the network through a mechanism called consensus.
Consensus allows actors who do not necessarily trust each other to agree on a single version of the truth.

3. Consensus Mechanisms
Several mechanisms exist for securing a blockchain. The best known are:
a) Proof of Work (PoW)
Used by Bitcoin.
Principle:
Participants called "miners" solve complex mathematical problems.The first to find the solution validates the block.They receive a reward.
Advantages:
Highly secureRobust historyDisadvantages:High energy consumptionSlow process
b) Proof of Stake (PoS)
Used notably by Ethereum since 2022.
Principle:
Validators stake a certain amount of cryptocurrency.The higher the stake, the greater the chances of validating a block.
Advantages:
Less energy-intensiveFaster
Disadvantages:
Risk of wealth concentration
c) Other mechanisms
Delegated Proof of Stake (DPoS)Proof of Authority (PoA)Proof of History (PoH)Byzantine Fault Tolerance (BFT)
Each model presents trade-offs between security, speed, and decentralization.
4. Fundamental Characteristics of Blockchain
a. Decentralization
No single entity controls the system.
b. Transparency
Transactions are publicly visible (in public blockchains).
c. Immutability
Recorded data cannot be retroactively altered.
d. Security
Protection is ensured by cryptography and consensus mechanisms.
e. Traceability
Each transaction can be traced back to its origin.

5. Different Types of Blockchains
a) Public Blockchain
Examples: Bitcoin, Ethereum
Open to everyoneFree participationComplete transparency
b) Private Blockchain
Controlled by a company or organizationRestricted accessUsed for internal purposes
c) Consortium Blockchain
Controlled by multiple organizationsHybrid model
6. Smart Contracts: Automation on the Blockchain
Smart contracts are autonomous programs that execute automatically when certain conditions are met.
Example:
"If payment is received, then transfer ownership."
They enable:
AutomationReduced intermediariesContractual reliability
7. Practical Applications of Blockchain
a. Cryptocurrencies
Bitcoin, Ethereum, stablecoins.
b. Decentralized Finance (DeFi)
Bankless lending, exchanges, and derivatives.

Human error, platform hacking.
10. Blockchain and the Future
Blockchain is still a developing technology.
Current Trends:
Layer 2 SolutionsInteroperability between blockchainsTokenization of real assetsIntegration with artificial intelligence
Conclusion
Blockchain is not simply the technology behind cryptocurrencies. It is a digital infrastructure that is redefining how trust is created and maintained in a digital environment.
It enables:
Transactions without intermediariesIncreased transparencySecurity based on mathematics
Despite its challenges, blockchain continues to evolve and could permanently transform finance, governance, logistics, and many other sectors.
Understanding blockchain today means better understanding one of the most transformative innovations of the 21st century.

When trading on Binance, users have access to a variety of order types, each designed to serve specific purposes in executing trades. These order types range from basic options like Market and Limit orders to more complex strategies such as One Cancels the Other (OCO) and One Triggers the Other (OTO).
This article provides an overview of the different order types available on Binance, including their specific functions and when to use each one.
1- Basic Order Types
The basic order types serve specific purposes and include few details. All order types require specifying a symbol (e.g., BTCUSDT) and side (BUY or SELL). We will discuss some of the most common: Market, Limit, and Limit Maker.

Market order
A market order is the simplest and most immediate type of order. When placing a market order, a trader agrees to buy or sell an asset at the best available price in the market. The order is filled as soon as it is placed, and the trader receives the quantity they requested based on the current market price.
The main advantage of market orders is their speed — they are executed right away, which makes them the go-to choice for traders who need to act fast. The trade-off, however, is that the final execution price may not be exactly what was anticipated, particularly when the market is moving quickly.
Limit order
Limit orders give traders the ability to set the exact price at which they are willing to buy or sell an asset. In this case, the trader specifies a limit price, and the order will only go through if the market reaches that price or offers something better.
This is a useful approach for those who are not in a rush and prefer to wait for the market to come to them. Limit orders can remain in place until the price condition is met, which might take minutes, hours, or even days, depending on market activity.
Additionally, Limit orders require the trader to specify a Time in Force, which defines how long the order stays active before expiring. The most common options are:
Good Til Canceled (GTC): The order remains open until it is either fully executed or manually canceled by the user.Immediate Or Cancel (IOC): The order attempts to execute all or part of it immediately, canceling any unfilled portion.Fill or Kill (FOK): The order is executed only if it can be fully filled immediately; otherwise, it’s canceled.
Limit Maker
A Limit Maker order works much like a regular Limit order but is designed to ensure it becomes a “maker” order, adding liquidity to the market instead of taking it. Sometimes called a Post-Only order, it prevents the trade from being executed instantly against an existing order.
Limit Maker orders can be especially useful for those who wish to control their trade price while avoiding the maker/taker fees that can arise from immediate matches.

2- Trading Exit Strategies
Trading exit strategies are essential for managing risk and protecting profits. These strategies include Take Profit and Stop Loss orders, which are used to exit a position at specific prices.
Stop Loss orders
A Stop Loss order automatically closes a position once the market reaches a certain price, helping traders limit losses when the market moves against them. For instance, if someone buys a cryptocurrency and the price drops to a set stop price, the Stop Loss order will sell it to avoid further losses.
A Stop Loss order can be set with a fixed price or a trailing stop, which adjusts automatically as the market moves in favor of the trader’s position. This trailing mechanism locks in profits as the market price rises, but triggers a sell when the market price moves against the trader by a specified amount.
Take Profit orders
Take Profit orders allow traders to lock in profits when the market reaches a predefined price. Unlike Stop Loss orders, which are triggered by a price decline, Take Profit orders are activated when the price reaches a level that results in a profitable exit. This type of order is particularly useful for traders looking to secure profits without having to monitor the market constantly.
Take Profit orders can be combined with Stop Loss orders in a single strategy, allowing traders to set both the price at which they want to take profit and the price at which they want to limit their losses.
3- Conditional Order Types
Conditional orders are more advanced strategies that involve placing orders only when certain conditions are met. These include orders such as Stop Loss Limit and Take Profit Limit.
Stop Loss Limit orders
A Stop Loss Limit order combines the functionality of a Stop Loss order with a Limit order. When the stop price is reached, a Limit order is triggered, allowing traders to set a specific price at which they are willing to sell. This order type can help prevent a sell order from executing at an unfavorable price in a rapidly moving market.
This type of order provides more control than a simple Stop Loss, as the trader specifies the price they are willing to accept, reducing the likelihood of selling at an undesirable price.
Take Profit Limit orders
Take Profit Limit orders work similarly to Stop Loss Limit orders. These orders trigger a Limit order once a predefined price is reached. Traders can use this order type to automatically exit a position when the price hits a certain profit target, ensuring that the trade is closed at a price that meets their expectations.
4- Advanced Order Types
For more sophisticated trading strategies, traders can use linked order types, which allow for greater flexibility and automation in managing trades.
One Cancels the Other (OCO)
An OCO order combines two orders into one. The first order is placed as a Limit or Take Profit order, while the second order is a Stop Loss order. If one of the orders is executed, the other is automatically canceled. This strategy is useful when a trader wants to protect profits while limiting potential losses.
For example, a trader might set a Take Profit order at a higher price and a Stop Loss order at a lower price, ensuring that only one of these orders will be triggered, depending on the market movement.
One Triggers the Other (OTO)
The OTO order type allows a trader to place two orders, where the second order is triggered only after the first one is fully executed. This strategy is useful for traders who want to place a secondary order that will only be triggered after a certain condition is met.
For example, a trader might place a Limit order to buy an asset, and once that order is filled, a pending Sell order is triggered.
One Triggers One Cancels the Other (OTOCO)
An OTOCO order combines the features of both the OTO and OCO orders. The first order is placed as a working order, while the second part consists of two pending orders that are linked as an OCO. These pending orders will only be placed if the first order is fully executed.
This order type is useful for traders who want to set up a more complex strategy that requires multiple exit conditions, such as a Take Profit or Stop Loss scenario.

Final Thoughts
Knowing how each order type works — from fast Market orders to complex linked strategies like OTOCO — allows traders to match their tools to their goals. The right choice can help automate trades, reduce risk, and improve overall results. Mastering these options can make the difference between reacting to the market and actively shaping trading outcomes.

The market is testing us. Yesterday, Bitcoin attempted to break through $69,500, but it was just a fakeout.
Why does the structure remain bearish?

Low liquidity: The order book is thin, making manipulation easier.
US pressure: The opening of US markets often brings bearish volatility at the moment. * USDT.D: The stablecoin's dominance is nearing 7,990. If this figure rises, BTC falls. It's simple math.
Two scenarios to watch:
The rebound: We hold the $66,500–$67,500 zone for a retest of $69,500. The fall: Failure to hold $66,500, heading towards the psychological zone of $60,000.

Tip: Don't trade hope, trade confirmation.
Poll: Are you "Buy the Dip" or are you waiting for a lower price?

Calm after the storm?
After the sharp fluctuations at the beginning of the week, the crypto market seems to be seeking a new equilibrium. This Friday, February 13, is not unlucky, but calls for analytical caution.
1. Bitcoin ($BTC):
The $68,500 support holds firm. Technically, Bitcoin has formed what analysts call a solid "consolidation base." Yesterday's rejection of $72,000 led to a healthy pullback that allowed for the purging of over-leveraged positions.
The indicator to watch: The Funding Rate. If it returns to neutral or slightly negative, this will signal an opportunity for a technical rebound towards $74,000.
The sentiment: We are moving from Extreme Fear to Neutral Fear. It is often in this zone that institutional accumulators place their limit buy orders.
2. The Rise of the Layer 2 Narrative:
While BTC stabilizes, attention shifts to scalability solutions. With gas fees rising on the Ethereum mainnet, ecosystems like Arbitrum, Optimism, and Base are seeing their Total Value Locked (TVL) skyrocket. By 2026, the battle will no longer be about "which blockchain is the fastest," but rather "which blockchain has the most daily active users."
3. Strategic Conclusion:
Don't be fooled by today's sideways price stagnation. Trading volume remains robust, indicating that the transfer of wealth from "weak hands" to "strong hands" is underway.

💬 Today's Debate: In your opinion, will the next major move be a breakout to the upside or a return to $60k? Explain your position in the comments!

As the global market searches for direction on this February 12, 2026, one asset continues to demonstrate quiet resilience: BNB. Far from being a simple exchange token, it has transformed into a true indicator of the Web3 economy.
The "Launchpool" Effect:
A Shield Against the Downside One of the reasons BNB maintains its support levels is the constant flow of new projects on the Binance Launchpool. In times of uncertainty, investors prefer to stake their BNB to obtain new tokens for free rather than sell. This creates constant buying pressure and reduces the circulating supply.
Decentralization via the BSC The Binance Smart Chain (BSC) reached new daily transaction highs this month, driven by Real World Assets (RWA) protocols. Each transaction burns a fraction of BNB, making the asset mechanically scarcer as adoption increases.
My advice: Don't look at the price of BNB in ​​isolation; look at the expansion of its ecosystem. Holding BNB in ​​2026 means holding a ticket to every major innovation launched on the world's largest platform.

The digital asset market on Thursday, February 12, 2026, is showing clear signs of maturation, but remains marked by nervousness stemming from recent macroeconomic decisions. If you're looking at your charts today, here's what you need to know to navigate the market wisely.
1. Bitcoin ($BTC): The Battle for $70,000 After a sharp correction in early February, Bitcoin is attempting to consolidate its position around the psychological pivot point of $70,000. On-chain data reveals an interesting phenomenon: while Spot ETFs experienced capital outflows last week, long-term HODLers are increasing their positions. The support level at $68,160 is currently the major line of defense to watch.
2. Ethereum and Layer 2: The Ethereum ($ETH) "Metamorphosis" stabilizes above $2,000 but slightly underperforms BTC. The real show is on the Layer 2 (L2) solutions. Transaction fee compression is driving mass adoption but poses a valuation challenge for the ETH token itself. This is a "Fat Applications" market where real-world utility is starting to outweigh protocol speculation.
3. Altcoins: AI and RWA Lead the Way. While memecoins are losing steam, the Artificial Intelligence and Real Asset Tokens (RWA) sectors are showing incredible resilience. Projects like Fetch.ai ($FET) and Render ($RNDR) are capturing the attention of institutional investors seeking yield based on a solid technological infrastructure.
Today's Conclusion: We are in a phase of healthy "clean-up." Short-term volatility is high (85%), but the fundamentals have never been stronger.
💬 Your opinion: Do you think BTC will break the $75k resistance before the end of the week or retest $65k? Let's discuss it below! 👇

The market has just gone through a rough patch. After nearly hitting $60,000 during a recent crash, Bitcoin is now trying to stabilize around $70,000. For many, the urge to engage in revenge trading is strong tonight. Here are a few reasons why you should remain calm.

1. Sentiment Analysis: "Extreme Fear" and "Dead Cat Bounce"
Sentiment indicators show clear fragility. Even with the rebound, volume remains low. Technical analysis associates a rebound with low volume with a Dead Cat Bounce, which is a short-term rise followed by another fall.

Tip: Don't confuse a technical correction with an uptrend.
2. Whale Movements
Enterprises like MicroStrategy and Bitmine continue to accumulate massive amounts of ETH (over 80,000 ETH for Bitmine in two weeks). When you panic, institutions buy. Watch the outflows from exchanges tonight: if BTC is being transferred to cold wallets, it's a signal of long-term bullish confidence.
3. Strategy for the Asian Session
The upcoming Asian session often dictates the trend for the following day.
Key support to watch: $68,500
Resistance to break: $72,000

Conclusion: The secret to success in crypto isn't predicting the future, but managing risk. If your stop-loss isn't set, then you're not trading, you're gambling.
