First of all,the drama of BCH getting pumped has ended.People have realized now that no other hard forks in future would be a threat to bitcoin since BCH itself has failed.Another aspect is that we are now seeing more effects of CME entering bitcoin market.Entry of financial firms in bitcoin has made the investors who had been traditionally investing in financial firms to turn their attention towards bitcoin.It is said that CME's rivals have also decided to enter the bitcoin market to compete with CME.All these aspects have a combined effect responsible for bitcoin's price rise.
