Do you understand anything about the BTC futures market ?? Explain to me how someone who is in the whole on a long futures contract is going to manipulate the market ?? To do so they would have to go out and start purchasing real BTC and still leave enough trading cash to pay the margin difference on the Futures contract. The number of Futures contracts sold is pitifully small in comparison to the Daily BTC volume so why would they all suddenly step up and go nuts ? Also do not forget the people who have sold the contracts and are currently in profit - do you think they will sit idly buy with all the Cash they have from the sale and let the price go up ? They would already be putting sell walls in place if your theory was true

The news, that future contracts bet on bitcoin ~8000 USD is impacting the price. Not the fact of future market themself
