Why do many people in the cryptocurrency circle say that even dogs don’t play with Chinese projects? Is there any precedent?

Chinese projects don’t know how to package, and they mainly focus on a simple and crude way of raising prices and selling goods, and then run away. They finish one project in half a month and then move on to the next one. In comparison, foreign projects are delicate, with a very technological page, VC platforms, Dr. XX platforms, various media promotions, and no rush to raise prices. They only hang leeks on the flagpole after half a year. Playing Chinese projects, you can see the door and start cursing after two months, and playing foreign projects, you still think you lost money because you didn’t study the technology well after two years.
