whos talking about regulating bitcoin.
Just the end points like exchanges, where it is necessary to entrust both fiat and BTC to a third party in order to be able to trade in real time.
Like when I buy a cheeseburger "in real time" at a restaurant and have to entrust both fiat and a cheeseburger to a third party?
Read above: requiring a license to exchange BTC and USD is what causes the consolidation, which is what causes the massive heists.
If I could convert BTC/USD at my coffee shop in the morning, I wouldn't have to store BTC in Mt. Gox (nor USD in My Bank, for that matter).
Would a coffee shop be willing to set up a terminal where they can offer this? I think you could convince them to do so. A coffee shop probably isn't going to be willing to get licensed as a money services business, though.
Does that require trust? Yeah. Buying $100 of BTC from a coffee shop requires about as much trust as buying $100 of electronics equipment from an electronics store.
