Hi all,
I tried to trade in listex.io, after trade I'd liked to withdrawal my BTC but I got failed all times. I tried different address and different ammount too.

I tried to ask on their discord channel but I was removed and banned few minutes later 

I don't wanna accuse anyone of scam but this acting is not very good to me...

Can anyone have experencies with them?

Thanks!
