You are right. Bitcoins and bitcoin businesses in general have taken a very American twist. The entire 'bitcoin foundation' had turned into nothing more than a lobby group which is what Gavin happens to belong to. Large bitcoin businesses are dominate by Americans so far: Coinbase and Bitpay.
Happy that Bitstamp isn't US owned but not sure for how long. It's basically a repeat of what happened with the Internet. No one is stopping other regions from taking their own slice of the pie. It just appears that Americans are quicker on the innovation front and seem to understand where future value may lie and thus take appropriate risks.
