As a student, it is enough to have a grateful heart. After a few times, they will also teach you how to place positions. As long as you believe in your brother K, he will not despise how small your position is. As long as you follow the instructions to place positions. Don't panic. No one will teach you how to control positions. #btc走勢 #ETH🔥🔥🔥🔥🔥🔥
