Dude, seriously? Why should the price be at ~$150/btc in Oct 2013, then $1000/btc merely 2 months later? Why should the price be ~$600/btc now instead of still at ~$4/btc as it was 2 years ago? "But Bitcoin!" Yes, that. Bitcoin hasn't fundamentally changed in years, it is still the same. So there are no facts that the "Bitcoin" from 4 years ago is really any different that the "Bitcoin" of today.
Please. Remove. Head. From. Ass. And. Research. Deeper.

Because "But Bitcoin!" isn't an answer. WHY does that mean it will be 5k? Financial freedom? Mass adoption by a country? Amazon? Specifics are needed, not HURF DURF BITCOINZ.
