If it's Bitcoin just HODL. It would be a stupid thing to sell in a bear market. BTC will still reach 100K one day if Putin won't drop the rocket and/or we won't have another COVID, there is always hope in this world.
Despite of market's uncertainties, bitcoin will always recover after every fall, and will always seen dominating the market. So there's no way to sell it particularly if the market turns bearish. Keep hodling until you see satisfying price worth to sell.
