I think with the CME group coming on board and other financial institutions also going to be trading bitcoin futures i think the price will go up by the end of the year, not sure it will hit 15k by December 31st though. I think with Xmas looming close trading will die down a bit but it will then pick back up after the 1st of the year. Only time will tell though and anything is possible. I would love to see bitcoin reach 15k by the end of the year but i don't think it will, shortly after the year I think it will hit 15k even higher. I'm hoping for 1million by the end of 2020 with any luck. To the moon!
