Look at all these shorters losing their shirts talking about MtGox coins LOL.  If MtGox coins are auctioned off, it would be 56 million at current price to many different bidders, not one party.  Sounds higher than your paycheck, but BitFury alone is building a 100 million dollar mining facility right now, so not exactly a big deal.  That and you have billions in VC investment in 2015 alone:

It's clear that the price per coin is highly lagged behind everything else going on, and these entities can all easily pump it higher, they're just waiting till they accumulate most of them first (i.e. after the 25coin halving since 70% are already mined).
