OKCoin presently does not serve customers in the following countries/regions/territories: Cuba, Iran, North Korea, Crimea, Sudan, Malaysia，Syria, USA [including all USA territories like Puerto Rico, American Samoa, Guam, Northern Mariana Island, and the US Virgin Islands (St. Croix, St. John and St. Thomas)], Bangladesh, Bolivia, Ecuador, and Kyrgyzstan.

They did not send me any email notice of this changes and I have few crypto there. I cannot do anything trade, withdraw etc.
So, I already email them a support ticket and let see how do I go from there.
