I have around 2k USD of btc and I wanted to swap it for something but I can't decide whether to buy eth or Solana both seem extremely promising in the far future.
That is very interesting swapping btc usd? Well it is yours choice, I will prefer you go for solana thou Ethereum is also good but considering your capital I think you will have more of solana coins than that of Ethereum as regards to their price in the market cap, however the ball is your court and you have to play it to your sole desire.
