It isn't legal in most US states. Almost all states have laws that dictate employees working within that state have to be paid in US currency

To cite one example, here's Texas:

And payroll taxes certainly need to be paid in US currency. The IRS and state tax departments don't accept Bitcoin.

They do, but it's classified as a "barter".

If you have the option to get USD instead of BTC, then you're much, much better off getting paid the former.
