I don’t think you need to worry at all. For now, it must be a long-term holding of Bitcoin. Don't sell at a loss. You must stand the test. It reserves generous rewards for those who are prepared and truly trust Bitcoin. What was the purpose of OP buying Bitcoin at the time? Certainly not the idea of selling at a loss. If you want to support that new stock, you can reduce your investment and try, but I think it is unwise to sell Bitcoin at a loss.
