Mostly for a project I don’t have much conviction on to do well, if I’m able to make my capital out of it after investing into the coin, I will end my investment there. For the ones that have some level of conviction and not still 100%, I take profit partially and make sure my capital is out before any silly move on the project. The one with much conviction on the project, I apply your rule to taking profit, get a target, then DCA my way through it and most importantly, the exit time I don’t miss.
