I stick with cryptocurrencies that I think are quality, they are probably at their lowest price right now, They are SOL, BNB and XRP. I don't mind for now, because now they can be bought in the red before the market goes up again.
Those coins are a good option besides buying bitcoin that still the first coin that we must buy. The altcoin will be an alternative to make a profit so you should not forget to buy bitcoin during the market crash. The top 100 can be another list for you to search for the other altcoins you can buy but not many altcoins can survive in the next downtrend because some of the altcoins can still get down. So it is not easy to pick the altcoin because it needs more research and deep analysis to find the right altcoins.
