Okex is also one of the exchanges that i like the most together with binance. Havent experience any difficulties or problem when j trade on okex, so i assure you that oken is a good exchange.
I agree that okex is one of the good and trusted when it comes to exchange, for me okex is on top 2 exchange next to binance in my opinion.
Trusted by whom? Certainly not the people they've scammed into (wrongly and needlessly) giving them their passport, driver's license and home address... ...nor by those that get locked out with zero way to speak to someone competent.
The measure of an "exchange" isn't really pointy-clicky ordering, it's how honorably they behave as custodians of peoples' money. In that, OKEx fails. Utterly.
