Okex is a digital currency exchange developed by Star Xu, who also created the OKCoin exchange. It was founded in 2014 in China, and is currently the second largest cryptocurrency exchange market in the world. OKEx differs from most cryptocurrency exchanges because it is built for seasoned and professional cryptocurrency traders.
Okex offers three verification levels. Level one allows you to sign up with a username, ID number, and nationality, access to most sections of OPEx, and limits your transactions to $2,000.00. Level two grants you access to all aspects of the OPEx exchange and a $200,000.00 transaction limit. You must provide more personal information, including a current photo and a copy of your identification.
They offer the first futures market for digital coins and has grown to be the second largest exchange in the world, meaning that if it lifts restrictions imposed on the United States and Hong Kong, it could quickly become the largest digital currency exchange worldwide.
