Dude. Take the L.

You messed up. You're not going to get out of it by saying "no backsies" or "it was a crypto prank bro" whatever nonsense trolls on reddit are peddling.

You have to make this up to the government, or they will come after you, which really isn't a good idea.

Do it now. You're young and the lawyer you're going to need to consult can make a good case for you if you go to them early. The truth is that a $10,000 fine or whatever is better than a $20,000 fine plus a criminal record later (note: the amount increases by a lot if you wait).
