Under the existing system in the US, just about anyone who actually uses crypto regularly can be charged for tax fraud/evasion if they don't have absolutely meticulous records kept of every single explicit activity.
Seriously though, I think that @ some point as crypto is more and more popular, they have to do something because otherwise millions of people will be criminals.
Of course, with the # of laws there are, we pretty much are all criminals already.
Or it might just not get more popular because the risk of becoming a criminal is so high :(
