U.S. derivatives traders are still using Binance despite the exchange’s claim of blocking U.S. residents.

A new report from Washington-based digital currency analytics firm Inca Digital revealed that U.S. derivatives traders continue to make use of international digital currency exchanges—including Binance, Bitfinex, and FTX—despite those exchanges claiming to block U.S. residents. Several base US-based users tweeted and bragged about particularly successful digital currency derivative trades, often backing up this braggadocio with screenshots.
