The fundamentals drive the futures. That is, the FUNDAMENTAL OUTLOOK for the coin is what drives the future price. It is not the other way around, in any market. If Bitcoin had any legs and the coin had value and base bitcoin traders saw that value and kept buying the coin, the futures would be going up as well.
When the base holders of the underlying start showing weakness in their belief of the thing to keep gaining value, the futures respond by shorting the future. If the basic fundamental holders suddenly start buying because they now believe in it, the futures will respond accordingly.
I feel the addition of a future on the coin has zero effect on the price of the coin. In my mind, the reason for the bitcoin crash is because bitcoin has only the value assigned to it, which is based on nothingness. That is not a good baseline to start from.
