Many people do not understand the meaning of doubling until they lose all their money and leave the market. They buy a bunch of copycats, but the overall funds may not double. The higher the certainty, the more visible the return, which means the lowest risk.

Buying at the lowest point and selling at the highest point will always be a cancer that retail investors cannot get rid of.

Only by having the behavior of "building positions at lows and selling at highs" can you walk independently.

I don't look down on doubling at the moment, I just hope to get my money back when the time comes.
