If you have money, don't go to Beijing, Shanghai, or Guangzhou; if you're in trouble, you'll inevitably rely on Ethereum.

Don't rush to find the "Holy Grail"; first cultivate your character. If you can't control your emotions, any system will be destroyed by them. The essence of stable profits is to tame the part of yourself that wants to get rich overnight.
The market has no "Holy Grail"; only entering in despair and moving forward with patience during hesitation. Remember Warren Buffett's advice: preserve your principal, preserve your principal, preserve your principal.
