If you sell your cryptocurrency and the price subsequently rises, you may miss out on potential profits, but it doesn't mean that you have suffered a direct financial loss. The concept of losing money occurs when you sell an asset for less than you paid for it and realize a loss. If you sell your cryptocurrency at a profit and it continues to rise, it's more of a missed opportunity than a financial loss. The decision to sell or hold depends on individual investment strategies, risk tolerance and market expectations.
