If the “Buy BNB” option is greyed out, it means this option isn’t available in your region. Due to strict financial regulations worldwide, Binance can’t be used in certain areas. In the U.S., Binance can’t be used in Connecticut, Hawaii, New York, Texas, Vermont, Idaho, and Louisiana. Certain countries in Europe and Asia also don’t support the platform. Users that have the “Buy BNB” button greyed out can try using a virtual private network (VPN) to access Binance or use an alternative platform.
