It's not Exodus, the exchange featured in exodus is shapeshift. Shpeshift might have considered your identity as that what your IP address revealed.
And the supported coins are too different for different regions. Like EOS is the latest to be restricted for US users. Using VPN would be fine with shapeshift for assistance you can contact them.
But all the coins? Even BTC and ETH or LTC, Dash, ect, every single coin listed in the exchange wont let washington residents of USA do any exchanging what so ever? Then why have the exchange at all if your not allowed to use it if your from the USA???
