I sold my ZEC long position at almost the highest point! I specifically reminded everyone yesterday to take all profits, and sure enough, a small K-line M top appeared afterward, and the coin price followed with a pullback.

In this kind of market, you really can't be greedy for that last bit of profit; otherwise, the profits you've made can easily be given back. Remember, if you make money, run away in time, and taking the profit while it's good is the reliable way!
