Based on Risk levels, this is what you can look into

1. Low Risk – Stable Gains

- Bitcoin (BTC)– Digital gold, strong institutional support, moderate yearly growth with lower downside.

- Ethereum (ETH)– Core smart-contract platform, staking yields ~4–6%, steady adoption.

- **Stablecoins (USDC, USDT)** – Pegged to USD, almost no volatility, used for parking funds.

2. Medium Risk – Good Gains

- Solana (SOL)– Very fast & cheap, growing in DeFi and gaming.

- XRP– Fast cross-border payments, clearer regulatory path.

- Cardano (ADA)– Research-driven, solid staking rewards.

- Chainlink (LINK) & Polkadot (DOT)– Key infrastructure for oracles and interoperability.

3. High Risk – Wild Gains (very speculative)

- Popular meme coins (DOGE, SHIB, PEPE) – Can explode on hype, but crash hard.

- TAO (Bittensor)– Decentralized AI, strong narrative potential.

- Low cap tokens in AI, RWA (real-world assets), or new Layer-1s – 10×+ possible, but most fail.

Always do your own research — crypto remains highly volatile.
