i´m pretty sure that BTC will continue rising in long turn.
still everybody who is hoping that BTC will be 10k$ in next year is to optimistic. we are now in price level where 1000% per year would make whole BTC-community to "closed elite community" and result would be (if amount of user does not grow), that BTC has very limited fiat-background.
so here my opinion:
5500$ end of ´14
8500$ - 10000$ end of ´15
15k$ end of ´16

to speculate what happens after ´16 doesn´t have now any sense.
