Re: Summer dip?!, December price outcome? ---> JOIN and guess the price GO!
You can believe whatever you like in terms of the BIGGER players abilities or inabilities to move the market or to take advantage of momentum to push the market further than what it might have otherwise gone, and even your seemly somewhat detached beliefs that BTC market has become "too big" to move. 
Brain tells me "too big" but brain also is reminded by everything else going on around crypto and fiat how pointless it is to rely on brain (for instance, the US dollar which was certainly too big to just allow to print to insanefinity, yet went ahead and did anyway). And god knows how many people thought $100 was too big, or $1000, as evidenced by countless hands letting go at those peaks, believing the unbelievable had impossibly happened and that that was it.
We've even got bloody JPM ascribing the true value "minus volatility" of Bitcoin today as way more than S2F's 130k range, so who's to say that very same weakness can't push price above and beyond what's "true"?
