If the site were still 'beta' and not taking out fees I'd be a bit more lenient. Taking fees implies a professional operation and therefore a level of expectation on information shouldn't be "just wait". As a customer I should be informed so as to reduce FUD. It's CoinEX's responsibility to reduce FUD...not mine to sit in the dark and accept the lack of information.
I hope they'll do okay...I like CoinEX, but my concerns for security are now completely overshadowed by the lack of customer service from a professional operation. We'll see if/how/when they come back and I'll decide my future based on their actions...
...till then, I'm just a mushroom...
