喝水就不困

This is probably a situation that all new beginners experience:
In June, I entered the market and bought 100u, when Ethereum was around 2000. At that time, I was just playing around and didn't pay much attention. I haven't operated for nearly three months.
In October, I started to operate again, and lost 100u.
In total, I bought about 10,000 yuan, approximately 1500u. I set buy orders before going to bed and reaped the rewards in the morning, with a win rate of over 70% without watching the market.
It's best to operate once from 400u to 900u, but human weaknesses are always greedy, and all my random operations during the day ended up losing everything.
Recently, the last time, ZEC fell from 500 to 430. Fortunately, I set a stop-loss and only lost 200u. Then, on 11.30, I placed an order for BTC at 90500 before going to bed, thinking that mainstream coins wouldn't have much fluctuation, so I ignored the stop-loss and even opened high leverage. When I woke up, the sky had fallen, and the only 500U I had was completely wiped out.
