Op, you created this topic in 2023, I don't know which coins you selected? What is your current investment status? If you had invested the entire amount in Bitcoin, you would have made a lot of profit today. However, $20k is a good amount to invest. Since investing in altcoins is riskier than bitcoin, if I had $20k I would invest 60% in bitcoin and 40% in some of the top altcoins. I used to invest 20% in Ethereum and 5% in BNB coin, 5% in Solana, 5% in MATIC, 5% in DOGE, hopefully still investing in these coins will give a lot of profit in future.
