Well this "mistake" so to speak could still be rectified by buying back bitcoin even at this price point. You could still recover losses in future pumps if ever, but you wouldn't be able to buy back losses anymore if you don't do anything today. As it stands bitcoin is showing good signs of a possible price pump for at least a good while, enabling everyone to still be able to take in profits if ever. In that case you just made the right choice. buying back and not letting the regret of panic selling get the best of you.
