PANews reported on May 17 that according to CoinDesk, the Movement Labs and Mantra incident has aroused widespread concern in the crypto market about the market-making mechanism. Some executives of Movement Labs were accused of colluding with its market makers to sell $38 million worth of MOVE tokens on the open market. At the same time, Mantra's OM token plummeted by more than 90% in a few hours at the end of April without any obvious negative news, raising questions about the token unlocking arrangement and the transparency of over-the-counter transactions. Analysts believe that these events expose the distorted effects of hidden contracts, non-public agreements and over-the-counter transactions in the crypto market on token supply and price discovery mechanisms. Several market makers are re-evaluating the token risk underwriting process and requiring project parties to provide greater transparency.
