See, here is the problem.
Someone disagree with you, and give you a place to reach more information, what do you do? Ignore the information and feel offended.

Who cares if you made money with his advice? Like you just said, in this market, anyone that call a coin will rise have 90% of chance to be right. So yeah, its kind of easy to be an "invertment guru" on cryptos....

Also, do some math on your trades. What would happen if had bought the coins you hade at random and just held them?
