It's normal to make payments with OKX. There used to be an OKLink wallet for OKCoin, and Xu Mingxing used Bitcoin to make payments for phone bills. At that time, Bitcoin was around 1500 RMB per coin, and the network transaction fee was a few cents. I even recharged it a few times, and I remember there might be discounted prices or similar post forums. So Xu Mingxing has always had the idea of making payments, and the cryptocurrency industry is indeed like this. Now, freezing cards is a big obstacle. If you can use U to pay directly or use U to consume, firstly, users' money will still stay on the platform, and secondly, it is also a necessity, after all, card freezing will not occur in consumption. However, it is still very difficult in the mainland. If the Chinese people are supported, the business can not be expanded. If it is expanded, it will be done. Maybe several departments will issue documents to do it.
