The source of funds report has to describe all actions you have performed with these funds before sending them to HitBTC, e.g. purchasing, exchanging, transferring from one address to another.
Kindly present the chain of events in chronological order. Please attach full-display screenshots confirming each step.

Jesus Christ, what is it they think you did with whatever funds you sent them? This sounds like a lot more than a simple funds-freezing because of a newly instituted KYC policy. I'm not exactly blown away that they'd ask for information like this, since I know that Coinbase keeps track of where its customers' funds come from and go to. Coinbase might be required by the US government to do that, but HitBTC? Where are they located?
i provided all my personal documents, and then they asked documents for the person who give me bitcoins. this is crazy impossible.
how can i force my friend to give me his personal documents, there is no way to complete this request.
That is indeed a stupid request, and they're likely hoping you won't comply so that they can just keep your funds.
I just became aware of HitBTC, because it's one of the only exchanges that lists Curecoin, a coin I've become interested in due to the project behind it (Folding@Home). I don't really want to buy any and have none to sell, but it figures such an obscure altcoin would be listed on an apparently crappy exchange like HitBTC--it's also listed on Livecoin, which I think is also a scam exchange if I'm not mistaken.
Anyway, I don't know if you're ever going to recover your funds, OP, but I wish you the best. I can't stand it when exchanges pull this type of shit.
