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?
It is definitely better to invest in more than one coin. But I think you should not over do it. I personally prefer to invest my money in three or four coins. So I will always have a chance for good results. But the excessive number of coins to invest according to me is not a good strategy.
