yes, at this time many people who hate the presence of bitcoin so that some say that bitcoin is haram. I do not think they can say that because not everything we do on bitcoin is haram. if we gamble on bitcoin and steal a bitcoin wallet then it could be called money they get is forbidden money, but if they work by trading and working on a bounty project then the money they get is not haram.
those who hate bitcoin will be very sorry in the future because bitcoin prices will be more expensive.
