Do you think retail investors frequently opening trades is an addiction?

Honestly, it's poverty. Not an insult, just reality.
They only have a few tens of thousands of US dollars, watching the K-line fluctuate hundreds of points up and down in a day, do you expect them to stay out of the market and watch?
Impossible. Every fluctuation in their eyes is like a chance to turn things around. Because they know very well that missing one could mean having to wait several more months.
Those who tell you "trade less, wait more, and go long-term" are essentially only suitable for people with capital.
They hold hundreds of thousands or millions of US dollars, can slowly wait for compound interest, endure setbacks, and miss a few market waves without getting hurt. But retail investors can't do that; their capital is too small, the time cost is too high, and life won't give you that much patience.
You wait three years to double your money, it seems stable, but the reality is: during these three years, you might have already missed two rounds of market cycles, and if you suddenly need money in the middle, you'll be forced to sell at a loss.
