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 think a portfolio should include a lot of coins. Many of them will end up in the trash bin in the end. We must constantly monitor the success of selected projects, only this will make a profit. Many projects stop development and this moment should not be missed.
