So why do they just leave it alone? And yes that is rhetorical.
I think the US government has to really think this one through. On one hand if they try to come in and regulate users of crypto will find ways to get around it. On the other if they do it in a manner that only regulated exchanges I think most people in the space will vary on as they have been. My question is this however. To what extent do they tax crypto? Do they only tax when converted into fiat? Or will they tax every Time crypto is used to purchase (which included crypto to crypto)?
