Why do you want your crypto to moon just so you can exchange it ALL back to your local currency and pour money back into the same broken system that made you desperate for your coins to moon in the first place?

I'm genuinely curious. I'm not talking here about those who are into everything crypto is or those who just take profit here and there. I'm talking about those who want to get out completely once they hit their goal.

I often see posts like 'What will you do if your crypto hits 1m?' and many serious answers are 'sell everything, buy house, retire, etc.' I obviously never had the patience to ask each and every such comment 'why?' so here I am: WHY? Why would you wanna sell everything and rely once again on the same system that made you seek crypto gains? Why would you keep your crypto gains in FIAT? Why rely on a 3rd party again to keep the majority of what you have safe? :)
