They'll tax your breath if they could. I think that the government has had its eye on bitcoin for as long as we've known about it.
It's interesting that they determine it as property. That's probably an excuse to tax it without determining it as an actual currency or money. It's like they want to collect from it but they won't admit that it exists. That's a bit hypocritical if you ask me.
I guess we'll have to see where things go from here and what the government has to say about crypto.
