Global crypto exchange Binance has taken a strong stance by banning a market maker due to misconduct related to GoPlus Security (GPS) and MyShell (SHELL) tokens. This follows findings from an investigation that revealed the market maker’s noncompliance with trading rules.

As a result of the misconduct, Binance confiscated $5 million in illegal profits. The exchange plans to compensate affected holders of GPS and SHELL, with further details on the compensation plan expected soon.

In the wake of this news, the price of GPS tokens plummeted by over 11%, while SHELL tokens increased by 6.5%. Additionally, Binance plans to introduce new mechanisms allowing token holders more say in listing and delisting processes.
