Bitcoin cash (BCH) continues to rally at a breakneck speed in the wake of Fidelity, Charles Schwab and Citadel-backed EDX Markets’ decision to debut on June 20, with BCH being one of the only four coins available for trading on the exchange. The cryptocurrency has gained another 30% in the past 24 hours to a 14-month high of $320, taking its cumulative gain since EDX’s debut on June 20 to 183%, CoinDesk data show. The latest price surge is backed by a notable increase in trading activity on South Korea’s most prominent digital assets exchange, Upbit.
