Binace is not encouraging USA traders in there anymore, just make your own research and you will see that i am right with this.
Personally I have only GDAX set up to buy LTC/ETH/BTC and move some to Binance for ALT trades.
Extremely happy with Binance, looking for another ALT site to store liquid trading pairs.
I like GDAX too, i have a friend of mine who is located on the United States and he is using his GDAX account, only that he is only using it in order to withdraw to his bank account everytime that he wants.
So all his taxes are reduced from each one of it's withdrawals.
