Of course for the many people who will do simple point-to-point purchases with bitcoin, these rules won't really apply, since those transactions and gains aren't detectable unless they're declared.

On the other hand, with retailers and 3rd-party apps adding Bitcoin payment layers, an increasing amount of bitcoin purchases will be on record and associated with an address or bank account in some way or another. I think it's good - we get both worlds and bitcoin grows.

I think they also did a good job of doing this without having it come off stiff or overly specific to Bitcoin. Doubtless things will be adjusted over the next couple years, but this is a big step in the right direction. (I also anticipate a couple small steps in the wrong one, but that's to be expected)
