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.
Most probably because US has strict laws regarding cryptocurrency and when you get into the US money laundering or tax accusation, you're f**ked.
That's why most of ICO's and exchanges blocks them. And they are particulary not happy when foreign company deals with their citizen without their consent.
Every business are afraid of US. Wherever you stay or operate, US is going to f**k you anyway.
Probably every shady business is afraid of US. We all seen a huge amount of exchange hacks that may be artificially made by the exchange stuff. So if you add different kinds of scam ICOs then the general picture would show that some kind of strict control is desperately needed in crypto field.
It seems like binance also have something to hide.
