I have received this mail from snip
In short, it is selective scamming. The complaints are piling up against HitBTC.
How much longer before HitBTC get shut down by authorities?
You're right. I think it's a new strategy from exchanges. They pretend a security issue on your account to block your funds and to ask you several personal documents.

It's more hypocritical than suddenly changing the terms and conditions without warnings, but less blatant...
It is less blatant to the unseen eye but for those that have seen this type of scam infest in the crypto community we can spot it a mile away...
They are selective scamming users in ever increasing numbers thus bringing about the end of their scam website closer and sooner
There would be no other way but this one would end up into that situation.They are just trying to make their business messed up and tending to go into the same
path where Yobit is currently on. Scam exchange but still operating in spite of few number of users,they do really like to victimize new users who arent even
aware into these kind of exchangers reputation.
