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.
I don't believe in your advice buddy because no good trader will this kind of advice of yours. We all know that there is no stability in the crypto currency market and not only in crypto currency market that such instability of price happen.
As for me, I see this period as a buying period and not selling period as you recommend, let alone for me to sell at lost as a result of panic that the down trend may continue till price reach $2k as you speculated above.
