I completely blew my account today. I started in March, deposited 500 yuan, learned with 68u, and after some contract losses, I gradually started making profits, reaching a high of 547u. Then I retraced by 200u, fought back to over 400, and have been hovering around 400-500, unable to break through. Later, I withdrew 368u, leaving one or two hundred to play with slowly. After a long time, my mindset has become less pure, and I haven't been able to improve. Today, my account is completely zeroed out. I really need to think seriously about this.
