To purchase OKD, a USD wire is made to the Trust Company's account in Hong Kong. OKLink will issue and credit your account with the equivalent OKD immediately. The reserve of USD will be held legally to you by the Trust. Neither OKLink nor other parties on the network have the right to redeem your USD.
You may sell your OKD on the platform for the exact same amount in USD. (1 OKD = 1 USD) and receive a wire in your USD bank account.
