The owner of $CRV used CRV as collateral and bought millions of dollars of stable coins. With this stable coin, he buys CRV again on another platform and opens 10x shorts in the short position. By selling the endless other coins in its possession over time, it reduces the value of the coin and makes a 10x profit in the short position. This process continues until the CRV coins offered as collateral become liquid. When the CRVs are liquid and sold by the collateral exchange, he makes a huge profit with the short position he opens. Now he does the same process in reverse and takes the money in the long position. I don't believe he did this alone. I can't think of anything other than thinking that if the senior managers in the stock exchanges remain silent about this situation, they are partners. This is an example of how to earn billions of dollars with free coins.
