You are some of a lucky guys who sell at that peak of price back in december 2017 i do hold a small amount of bitcoin that time but not lucky to sell it in a peak of price because i realy need money that time so i sold it in around 15,000$ only.
With that price of $15k I will also grab that profitable price when I really need it badly during emergency times. If you're in financial issues you can't prevent or control your emotions, that weakens your hands to sell your holdings. But if you only think of selling what you only need, then sell half of it and not s a whole amount of btc.
