Look at the markets, it is a literal Red Sea of Destruction

If you are still in a profit, take some or all of it off the table while you still can.
You may never get another chance.
Once the price gets too low many exchange will go out of business and you'll lose access to your coins.

If you will need that money in 10 years, then get out as much as possible even at a loss.

No crypto is worth buying at the moment,

Good Luck.

FYI:
Don't even pretend bitcoin price is stable until it is down to $2K.
