It is not a good sign, as this $37.55 Billion will inevitably put pressure on the Bitcoin market in order for a correction of some kind to occur when these contracts approach their expiration date. The daily trading volume is around 25 billion, so I expect a correction to occur as the date of their closing approaches, but in general, the more betting in the market. Futures are an indication of the entry of more liquidity into the spot market, whether negatively or positively.
