I quoted your message and posted my reply in that thread. That also got deleted.
I came to know about this exchange just today. So I am not sure whether this is true or wrong.
Well, here is how it worked for me.
I had some altcoins and found a good rate on Koinbi.
Deposited my coins, traded, but when it came to withdrawing, 2FA didn't work.
The only way of contacting support is their email (
support@koinbi.com).
Sent an email more than a month ago. No reply.
Messaged on Twitter. My message went nowhere.
If you don't believe me, you can go ahead and trade. I heard about someone who was able to withdraw, but I know another guy who couldn't.
So whatever you deposited,
there is a high chance it'l become your donation to the scammers.
