According to Fortune’s sources, the US Commodity Futures Trading Commission (CFTC) is investigating Jump Trading’s cryptocurrency trading unit.

Journalists emphasize that the investigation by the regulator itself does not indicate the illegal activities of Jump Crypto, especially since the cryptocurrency division left the United States last year. Perhaps the CFTC wants to understand to what extent the “departed” companies are still present in the local market. It is not yet known whether charges are being prepared against the company.

A Jump Crypto representative declined to comment. The publication notes that despite the approval of spot Bitcoin ETFs at the beginning of the year, US regulators and law enforcement agencies have maintained their tough stance towards the industry. Representatives of the cryptocurrency industry have repeatedly warned that such an approach could force them to take their companies abroad.

In September last year, it was reported that the profits of cryptocurrency market makers decreased by a third.
