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.
Day trading is also great to work with, but with so many cryptocurrencies out now, it doesn't mean you have to try all of them that just a few are already very good at making a profit and it saves one more time doing research on all types of cryptocurrencies.
