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 U.S. 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 waiting several more months.
Those who tell you "trade less, wait more, and hold long-term" are essentially only suitable for people with capital.
They hold hundreds of thousands or millions of U.S. dollars, can wait for compound interest, endure setbacks, and miss a wave or two of market trends without harm. 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, which seems stable, but the reality is: during these three years, you might have already missed two rounds of market trends, and if you suddenly need money in the middle, you'll be forced to sell at a loss.
