I know that there are many kinds of alternative coins existing today, but is it better to have that many coins instead of having just a few? What are the benefits and harm in having that many alternative coins?
I don't know of any harm in acquiring more altcoins but of good. Maybe harms could be if your hard earned cash is used in acquiring most of the coins and they all dip at same time resulting iñto a loss. But if you earned them via bounty, it is all good to you.
