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?
Diversification is the key to a healthy investment portfolio. So it is always better to have more different types of coins. However, if you are going to invest out of your pocket then be choosy and always research before you leap in with your hard earned money. But if you are targeting ICO bounties where you don't need to invest out of your pocket, try to join as many as possible. Because out of 10 bounties you will receive, you will probably see value in two or three coins and rest all may be useless. So for bounties, definitely try to have as many as possible, but when it comes to investment, research well before you jump in. Because if you don't research well, you may end up loosing your entire investment.
