In response to the current so-called blood-sucking problem caused by BN's continuous listing of new VC coins, a solution is proposed to add an exit mechanism. That is, to carry out healthy competition under poor market conditions, and to sanction bad coins in today's market. Those who once performed poorly and did not improve will be moved to the observation area. If the project party has not made any progress, it will be removed from the shelves. By adjusting and improving the market, funds will not be transferred blindly, and poor VC parties will not be able to rely on unlocking and painting big cakes every day to cheat investors' money, leaving a mess after the locust-like sweep of the Mao Party. Under healthy competition, in the current token distribution model, the situation of waiting for death after listing a larger CEX and painting a big cake and unlocking indefinitely will be better alleviated. The market will always look forward to new forms of chip distribution.
