This was the
thread that got a lot of upvotes on r/Bitcoin. OP made another
thread this was just today and binance's support gave the same comment on the current situation.
If I had that kind of BTC and Binance froze it I would immediately fly out to their office negotiate with them to settle this problem once in for all or at least speed up the process since you said the local authorities doesn't provide much of a help.
after reading that reddit thread, it's really obvious that's his only option. the likelihood that he's already given in-depth ID documents to phishing scammers is extremely high. binance freezing the account is in his best interest.
OP, your account is worth 1200 BTC. surely you can arrange to fly out, retain a counselor and deal with this in person at binance's offices. why bother continuing to post here or on reddit?
