Bithumb, one of the largest cryptocurrency exchanges in South Korea, has announced that it will be rebranding to Phantom. The rebranding is part of a larger effort to expand the exchange's global reach and to attract new users. The new Phantom brand will be more modern and sleek than the current Bithumb brand. The exchange has also announced that it will be launching a new website and mobile app as part of the rebranding. The rebranding is expected to be completed by the end of the year. Bithumb customers will not need to take any action as part of the rebranding.
