Coinbase (COIN.O) and Binance.US, two of the largest crypto exchanges by market share among those operating in America, have lost ground this year. Bitstamp's global market share among exchanges operating in the U.S. has risen to about 9%. Coinbase and LMAX declined to comment on the data, while Binance.US - the American affiliate of the world's largest crypto exchange - didn't respond to a request for comment. It may not be that simple for hungry challengers to grab market share, according to market players. In years gone by, crypto exchanges could swiftly gobble up business by offering access to a swathe of coins.
