I guess, but unless you bought in past few weeks, you’re still way up. This is more likely a huge payday for those who held long and liquidated at year end.
The payday comes when you actually liquidate your position, and you get the funds out of the exchange.

If you goal was to buy a house and house prices suddenly increase, even after you cashed out your bitcoin, you might still be disappointed.
Nothing wrong with taking risk, but dont pretend you're not gambling.
