$BTC Bitcoin (BTC) is a decentralized digital currency that allows peer-to-peer transactions over the internet without the need for a central authority like a bank. Launched in 2009 by an anonymous creator known as Satoshi Nakamoto, Bitcoin operates on blockchain technology, a secure and transparent public ledger. Its limited supply of 21 million coins makes it a deflationary asset, often compared to digital gold. Bitcoin is widely used for investment, online purchases, and as a store of value. Its price is highly volatile, influenced by market demand, investor sentiment, and global economic factors. Bitcoin continues to shape the future of digital finance.
