But why? US, according to the chart is giving them the most traffic so far and banning them doesn't make sense to me. I know I'm lacking information so I hope someone would fill us with this topic.
They are restricting the US users for a reason, the authorities are constantly putting pressure on them to comply with regulators and since they are not complying with them, they have to restrict the users and you will see more exchanges succumb to the pressure from the authorities and now we see in the news that bittrex also took the same stance as binance.
