They are 100% scammers. I read other situations. Sudden KYC wich contunues 3 days including using support, wich refuses to accept documents in emal. Pulling time and try to steal your money 100%. [and no guarantees that they will not sell my private documets !!!!]
When you use exchanges that are shady including Crex24, HitBTC, Bittrex and many others and you're trading with a fairly large amount of funds you should accept the fact that they will ask for KYC verification at some point down the line, some of them go out of their way and even ask for "source of funds".
Anyways their end goal is to make you tired of all the verification and leave them with your money, and there were even some cases that they did ask for more documents that just basic KYC information and source of funds, because obviously they want to make you worried about your privacy so you don't complete any verification so that they have all the money in your account for themselves.
U can not verify after registration!!! There is a message "you don't need verification".
And on Hit and Bittrex u can pass KYC right away. There are no problems with Hit either Bittrex. U register, u pass KYC u trade any volume include 100 BTC per day... 100 BTC, Karl.
Even Bittex when ask about fund investigation your accaunt is NOT FROZEN U can take all your money!!!
And CREX24 is SCAM. they frozen acc u can do nothing, even trade!!!
CREX24 SCAM!!!
