Since FTX and other exchanges have consecutively encountered user API key leaks and token theft through contra trading, a U.S. user has reported that Coinbase has also suffered similar issues, according to Wu-talk Reports. On October 22, his account unexpectedly contratraded RLY, QSP, FOX, FIS, MCO2 and other tokens, resulting in a loss of around $7,700. Additionally, he asserted that he never used 3 commas. Coinbase advised the user to call legal enforcement because they were unable to handle the situation. Users that using API KEY in connection with trading robots should be especially aware of these risks.
