Is it best to wait for the daily line to close with a big bearish candle and then short after a rebound?

Half-Year Profit and Loss Summary
First, the biggest mistake was 81 running away, not fully capturing a hundred thousand rise
Second, the recent pullback is due to shorting and messing around with altcoins
As a result, the funds are currently unable to return to the highest point
So
No one is perfect
You can't possibly earn all the money
Face your imperfections calmly
Life
Isn't it the same?
