What percentage gain did you see since 2004?
While I only started in 2017 ( and crypto got me 3 years worth of doubling in 6 months). I wouldn't change my strategy for 1/3rd and watching daily.
I also get out when I think it's the wrong moment. Eg. I only vested 30% now ( at least until end of December). And no, i don't do crypto anymore, got out at 18 k around end of 2017.
