There is a view circulating in the currency circle that it is because the project parties of most of the newly launched projects usually have a lot of bargaining chips in their hands. Through a series of hype and publicity, they attracted a large number of investors to participate, and the popularity of the project rose rapidly. Investors use real money to buy chips in the hands of the project party until the project party loses its ability to control the market. At this time, the project often comes to an end. In the next round of bull market, if you want to hype old projects again, who will come to pull the market? After all, the project party is unlikely to spend money to buy back the chips in the hands of investors. Therefore, some project parties would rather choose to launch new projects and borrow the enthusiasm of old projects to harvest the market again.
