How to survive in the cryptocurrency world, this is a matter of personal perspective—everyone has their own opinion. Of course, there are many ways to reach Rome; there are numerous methods to make money. The key is to follow the trend and unify knowledge and action. However, in practice, human emotions often influence trading strategies. Sometimes, observing the trend is more important than watching the price. Looking at Ethereum's long-term movement, whether the price is at $300 or $3,000, there will always be buyers and sellers, profits and losses. Ultimately, making money depends on the trend. Grasping the overall direction is essential to stay invincible.
