OKCoin, a China-based digital currency trading platform, has stopped accepting bitcoin deposits from customers in the US. It cited regulatory pressure as the reason behind its decision, as reported by CoinDesk.



When trying to make bitcoin, litecoin or US dollar deposits, OKCoin users based in the US see the following message:



"Notes: Due to regulation, we don't accept the charge from the US."



Calling the measure "temporary", the company did not reveal much when asked when the restriction will be lifted. A representative described the situation as "not very clear".



Jack Liu, head of OKCoin's international division offered additional details by email, telling CoinDesk:



"The latest change is part of an internal review we made on our policies and affects Level 1 individuals who self-indicated as US citizens."



He suggested the move was voluntary, but provided no further comment on the situation.
