This disparity in fee structure favors users outside the U.S., where the higher fees may be related to tighter regulation of crypto in the country. By comparison to other platforms, the fee structure of Binance.US and Binance looks more complicated. Users from outside the U.S. benefit from lower fees.
Binance.US does not provide information on an internal wallet offering, but you can keep your coins within your account on the exchange. It also partners with Trust Wallet, a third-party hot wallet option. You can withdraw your coins from your account onto your own hot or cold storage option at any time (for a fee).

Some experts have already expressed concern that the inclusion of the Binance Coin on the platform may prove controversial in the United States. While Binance.US is described as a subsidiary, its business model might draw attention from the U.S. Securities and Exchange Commission based on the fact that BNB token acts as both a security and a utility token. As such, it could pass the so-called Howey test for being security, thus potentially becoming a snag on the Binance’s path to establishing itself in the US.
Because most cryptocurrencies aren’t regulated by national governments, they’re considered alternative currencies — mediums of financial exchange that exist outside the bounds of state monetary policy.
