Haha, I have done at least half of those mistakes you mentioned :) Can add one thing: Never trade with borrowed money or money you cannot afford to lose. Worst thing to happen would be if one falls victim to FOMO and goes all in with all the credit he can get from bank or something like that, only to see price go down next day. And don't do margin trading - chance to earn more increases, but so does the risk to lose more.
