Genie is out of the bottle so just like the supposed threat to stop printing $100 bills (too entwined in worldwide cross border activity - legal or otherwise) U.S. won't say boo about Bitcoin. If anything Bitcoin etc might be the reason the $100 paper bill will become outdated at some point and taken out of circulation.
. Basically all encryption hacks demand payment mainly in bitcoins, and these last few weeks they were able to get into larger systems... so I was kinda saying that we did have that scenario what you pointed to.
