I'm hearing many long time maxi holders say the same thing. The experience of not taking even a little profit during bull markets and then being thrust into brutally long bear markets takes a toll. Andy Edstrom on the recent episode of the Bitcoin Matrix podcast comes to mind.
I'll also add that if we hit 1M a coin this year you'd be crazy not to shave a little off because more than likely we'll see the dump of all dumps and possibly never go back to that level again for a few years.
