Ethereum (CRYPTO: ETH) and Solana (CRYPTO: SOL) are two of the most successful cryptocurrencies, both ranking in the top 10 by market cap. Because Ethereum launched in 2015, five years earlier than Solana, it established a big early lead in terms of popularity and usage. Over the last year, Solana's price has risen by 10%, whereas Ethereum's has fallen by over 30%.
