I just found out that the CEX section of @ arkm_zh has a contract experience fee of 110 yuan that can be redeemed. You only need to recharge $100 and complete KYC to claim it. Chinese users can also register, and if you have time, you can go and redeem it. • Official website: https://auth. (arkm.com)/register? ref=killthewolf I have always used Arkham as a tool for on chain data analysis and address tracking, but in fact, their CEX section is also very good. They have both spot and contract options, support more than 20 mainstream currencies, and currently have activities. Trading can earn points, which can be exchanged for ARKM tokens in the future.
