$BTC In the ever-changing cryptocurrency contract market, the rise and fall of K-line is as unpredictable as the tide. Many investors chase high prices due to greed after a short-term profit, or stop losses hastily due to fear when they suffer floating losses, and eventually return home empty-handed. Mentality training is like forging armor, which needs to be tempered by market fluctuations. Only by learning to stay calm in the ups and downs, and adhering to discipline when stopping losses and taking profits, can we transform mentality into the core competitiveness of trading, and steadily move forward in the cryptocurrency world full of temptations and risks, and sail to the other side of wealth.
