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.
As long as you are investing in those coins with long term profitability, whatever happens to the market, always chose to HODL. That is if you want to avoid losses and be profitable in the future. The market won't always be bullish, so we should have separate plans other than hodling in case the market stays being bearish.
