Solana (SOL) has overtaken Binance Coin (BNB) to become the fourth largest cryptocurrency by market capitalization. With a market cap of $89.3 billion and a 35.14% increase in the past week, Solana's growth signifies an emerging challenge to established rivals like Ethereum. The surge is fueled by increased investment and on-chain metrics demonstrating a thriving ecosystem in decentralized finance (DeFi). With investors speculating on a potential challenge to Ethereum's dominance, the recent performance against Binance Coin raises questions about Solana's future position in the market.
