Normally, this would set a limit on the price of BTC, but since the filthy rich see normal people as gum under their shoes and don't care about their needs or wants at all, I think bitcoin very well has the potential to go to $10,000+, with $20-$200 transaction fees becoming the norm.
That's OK because other more affordable, universally-employable cryptocurrencies are already in existence by the hundreds, and bitcoin will simply be the coin of Wall Street.
sorry to disappoint you but bitcoin is not some little stock that only belongs to and is being traded in US. it is a global thing that many different people from different places around the world with different economical backgrounds are investing in it.
have you even checked the volume that has been coming from China?
how about the volume that has been coming from Japan from the start of this year and specially after their biggest Forex broker added bitcoin to their platform?
in bitcoin, it doesn't matter how big you think you are in the fiat world (aka the wall street dudes) you will be a tiny fish in the see when it comes to bitcoin with all the whales that have been around for a while to accumulate lots of bitcoin.
