Btc has run too far too quickly possibly due to manipulation by hedge funds. But it wont crash too hard I think. By guess is undervalued alts will rally hard now. Just a guess
It looks like your speculation came out as true because right now many undervalued or cheaper alts are surging by over 50% like NXT. After this price of bitcoin might start to again surge..
Its now time for bitcoin all alts might get bloodbath when bitcoin will start its new rally.
