nope, it not say anything about using bitcoin/cryptocurrency/digital currency is illegal. it illegal if you not declare it or use it illegally.
also know almost every parts of u.s government already recognized cryptocurrency as asset or other form of currency/asset.
don't forget everyone love the techs, included the u.s government them self.
if this bill is passed it mean nothing to the crypto world, if someone caught in this drama bill they would of just referred to irs who already said bitcoin classified as asset. it probably illegal in the use case kind of way, like funding terrorist using bitcoin, even fiat is illegal.

this poster have no clue of the bill and should delete or change the title of the post.
