Very true actually. It is important that crypto traders learn to trade. A part from the fact that too many persons may prefer to just buy and HODL probably to make more profit on  the long run, it is more ideal that one learn crypto trading for the purpose of learning the skills involve so as to become an outstanding personality in the crypto world.  I understand that if one does well in trading, he can make good money within short while like you stated in your comment. I guess the reason why too many persons out there are HOLDING is probably because the current worth of their coin is around their capital or below it and cannot afford to sell below or around it so they are left with the option of just HOLDING pending when it improves.

However, your opinion is quite an interesting one.
