When it comes to DeFi coins, some popular options to consider are Ethereum (ETH), Uniswap (UNI), Aave (AAVE), and Compound (COMP). These coins are at the forefront of the decentralized finance movement and offer various benefits. Investing in DeFi coins can provide opportunities for yield farming, lending and borrowing, decentralized exchanges, and participation in governance. However, it's important to do thorough research, understand the risks involved, and consider factors like project fundamentals, team credibility, and market conditions before making any investment decisions.
