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's no scamming. If you didn't notice after completing KYC people withdraw their coins. No one gets robbed.
False. Many users report giving all the requested data and still not receiving their money.
Besides, the KYC/AML procedure is invoked for even the smallest of amounts, like $50. This is not a practice focused on security. It's simply scamming, stalling and as mentioned above, possibly even identity theft.
HitBTC has never even tried to prove the IDs/documents are secured and the KYC requests are in any meaningful way justified. It's clear from all the complaints that a lot of users were directly harmed by the exchange and its affiliates. HitBTC is an unscrupulous and shady exchange. Avoid it like a plague.
