Binance, the world's largest crypto exchange by Real 10 volume has announced that it will review customer accounts on its site to ensure they adhere to the exchange's KYC and terms of service policies. As part of its updated terms of service Binance will not provide services to "any U.S. person." Previously Binance only restricted access to six U.S. states, including New York. The move comes one day after Binance announced a new U.S. based exchange.
