Currently there are more than 19K Cryptocurrencies, of course it is impossible for us to only rely on investment in 1 or 2 coins, if problems occur like Luna will certainly make us cry, the many choices certainly provide great opportunities for us for big profits, and for now I prefer daily trading that is buying new listed coins.
With that many coins and tokens I don't think it's a good move if you're trying to invest in multiple places. But you also can't put all your assets in one place. You can try to invest in coins or tokens that already have good fundamentals. You can choose old cryptocurrencies that are more than 2 years old. It is important to reduce risk by trying to invest in new coins or tokens.
