I asked them today if they have some date for going online, they answered:

Dear Sir,
Our API is closed currently.
And we are bringing Bter up. There is no specific time yet and we are enabling the function gradually.

Please kindly follow our tweet for the update.

Best Regards

Hello Frangomel,

Your request has been submitted and will be reviewed by our development team.
They will decide to add the coin to the exchange or not. Unfortunately they will not
be able to contact you but they will announce if they decide to add this to our exchange.

Thank you.
