Since you are planning to invest your $2000 in Ethereum and Solana coins, in my opinion both coins are better to invest. This time Bitcoin price set a new record before the Bitcoin halving. Solana and Ethereum coins pumped well due to the hype of this Bitcoin price increase although they did not break their past records. Solana in particular pumped up a lot, Solana went above $200. If the bull season begins after the upcoming Bitcoin halving, the price of Solana and Ethereum coins will be increase significantly even they enter new highs in value. So I think holding 70% in Ethereum and 30% in Solana will give good profit in future.
Currently, the market is in correction mode which has resulted in the price of both SOL and ETH going down. With an initial amount of $2000 and if invested all of it to buy SOL, OP will eventually have approximately 11 SOL ($188). He can keep those SOLs in the phantom wallet and can stake them, get airdrops, swap some SOLs for meme coins, and enjoy more profits than investing in ETH. Later on, when the market is in green he can easily get a good amount of profit from the price rise. I think investing in SOL would be the right choice in the current situation than going after ETH.
