The fluctuations in the cryptocurrency market are really quite dramatic; sometimes it rises several times in a day, and other times it drops, making people anxious. I have discovered that what really affects your profits is not the market, but your own mindset. Don't let short-term fluctuations scare you away, and don't be greedy when prices rise. First, set a strategy, control your positions, and manage risk. Don't panic when you lose, and don't act blindly when you profit; this way, you'll be stable in the long run. Investing isn't about luck; it's a competition of psychology and patience.
