Didn’t Binance register a separate exchange in the US that functions in accordance with the established regulations?
They did, though certain states are prohibited from using the site. I'm not sure about the derivatives part of this story--is this all about tax evasion? If it's not, there are legitimate ways for US residents to trade crypto derivatives (like Bakkt and the CME).
And yeah, anyone doing this sort of stuff illegally is just asking for trouble now that the Biden administration has taken an interest in off-shore tax shelters. Even if it's crypto we're talking about, any shenanigans is bound to be discovered sooner or later.
the IRS is one of the most punitive taxation organizations you'll find, along with extensive resources at their disposal.
That's true, but they're also fucking corrupt as hell, and I thought they had been de-fanged somewhat a couple of years ago after that scandal involving the Tea Party. I'm not wishing them any luck in any of their endeavors.
