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?
I've been in this kind of situation many times too. From my personal experience, presently I would only invest in very few coins (say 3 to 5) only. Going for more creates more problems for me.
