Crypto investing, mindset is king, position size is the foundation. Don't be greedy or impatient; only earn profits you understand. When the right opportunity arises, decisively take profits and secure gains immediately. Strictly control your position size—avoid over-leverage and all-in bets, leaving enough safety margin to move freely in and out of the market. No matter how many market temptations there are, stay true to your original intention and don't be swayed by greed. Always remember, the biggest enemy in investing is greed. Only by avoiding greed can you sustain long-term success. Steady and cautious, with a slow and steady approach, is the long-term way to survive in the crypto world.
