Eventually, I received a reply from Bter customer service and I am able to withdraw now.
So although it takes time to resolve issues, Bter is still alive!
Yes they are "alive" after 3 hacking / scam , and more then 1000 btc to repay to old user like me.
My suggestion? DON'T USE this site, you can get a really big scam!!!!!
Do you ever seen any exchange you could withdraw after 3 hackings? most exchanges refused to pay user after hacking but Bter paid something to their users, I don't think it "scam". They did pay your withdrawal.
