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?
no, it's too risky in my opinion, I prefer to invest with a number of altcoins.
to minimize large losses, if there is one of your investments that loses at least there is still hope for your other investment.
