I think just the proposition, whether it becomes a law or not, is a positive for crypto as a whole, because it allows those who are just at the edge of crypto to see that there are efforts afoot to "legitimize" crypto by addressing digital currencies directly, by law.
Whether it will mean much functionally speaking, it means something in terms of soothing those inclined to think "but what if crypto is ILLEGAL?"
Yes, we're keeping our coins!
