I've been thinking a lot about this issue. I heard more than once that many are discussing this topic. Is it safe to invest everything in one, two cryptocurrencies? Or to distribute all the money in all the coins available for this amount?
At the moment, I just keep everything in the top coins, including bitcoin, to invest in a variety of simple coins is very dangerous now, until the market stops, it is better to make simple investments that are the most prosperous.
