BTC Price Manipulation Theory

The reason for massive dips in BTC, the market leader, maybe the fact that CBOE futures contracts expired. The first of its kind gave opportunity to Wall Street traders to speculate on BTC. If all these investors shorted BTC it would behove them to see the price, around $17,000 at the contracts offering, drop significantly to around$10,000. Is it a coincidence that this happened? Who knows! The fact is they made good money on those shorts and the market played into their hands. Next step, I would assume a long position on futures seeing as markets usually arbitrate strategies of manipulation out. So, is the accumulation phase entering another run. As we see the price above $12,500 we are testing a possible run to correct for this manipulation.
