I am not a mathematician, but it seems that there is probably a greater likelihood that if BTC does gain mass adoption, then the price could  just as easily be $100,000 as $10,000 per BTC when divided out by the number of people using it by the amount of money invested in it.  The question really is will it gain mass adoption?  If so, crazy high numbers, if not, our BTC will be worth much less.  Granted, there may be some use for it on smaller scales so I guess we could say that $1000 each is possible but it is something to think about.
