CoinMarketCap, arguably the most prominent global index of cryptocurrency prices, triggered a wave of anxiety and anger this morning when it removed a group of Korean cryptocurency exchanges from its price calculations.
Though the change was apparently made at midnight Sunday U.S. EST, CoinMarketCap did not publicize it until midday on Monday, saying that the Korean exchanges showed “extreme divergence in prices from the rest of the world and limited arbitrage opportunity.”
