It is an exchange that has been serving without any problems for many years. But as a result of the police raid, users' operations were disrupted, leading to a loss of trust. Okex Exchange has great bonuses for its users, but it implements ridiculous policies so as not to withdraw this bonus. It forces its users to trade hundreds of dollars. If the Okex exchange was to distribute airdrops, it should have done it for free, should have done unconditionally. Also, the volume in the stock market seems a bit doubtful.
