The overall liquidation of tens of billions of dollars, mainly targeting market makers and active traders, has caused far more damage to the market than one might imagine, as other crypto investors are inactive traders holding their coins. This is especially true for Altcoin that have been driven to zero with a single click. It will take a long time to restore investment confidence and liquidity. It is strongly recommended that exchanges set aside some of their profits to establish a liquidity regulation fund to avoid extreme situations where liquidity is exhausted and the market is driven to zero. The Federal Reserve also has market regulation.
