My Bitcoin withdrawal on BTER.COM gone/disappeared to "wrong" address ! (SCAM?)

[cube]

I am sorry you are facing this.  Two possible scenarios :

1) Bter is hacked.  You should quickly contact Bter support and check with them,  or

2) Your PC is being hacked or it got a malware infection.   Your could be a victim of a phishing attempt.   The Bter website you are accessing was a fake and you were sending information to a fake bter.  Or your PC could be remotely controlled/spied on and your transmissions were being altered.  You should do a immediate full and thorough anvirus/anti-malware scan.

Before 5 days (10/10/2014) I made a withdrawal request on BTER for 0.5 bitcoin and wanted the funds to go to address
129mztHAP1VUMWn2BdTrNCEUpfDPVpkHEq (because I wanted to sent them for the bitshares music presale  :'()
Now I realized that "my" 0.5 bitcoin is gone  to address:
16LLwLZcEC7YM2L5NPwGLdSRTQNk3S67pM
that not belong to me!!!
The weird thing is that on the last 10 transactions history on BTER it is supposed I have sent  two more times to the same address!
I don't remember these transactions but it is possible I have lost some more funds the same way and I didn't noticed until now  >:(....

With further investigation via https://blockchain.info/address/16LLwLZcEC7YM2L5NPwGLdSRTQNk3S67pM
I saw that the funds arrived  on the "wrong" address" after 2 days and one day after they have gone to:
16PXucAgi9N8LPqAxyNud1ySuVVCQRQ9bZ

With a little googling I found that the last address is associated with SCAMS and is owned by a scammy exchange https://www.coinexd.com
more users have lost their funds and have "see" them on this particular address 16PXucAgi9N8LPqAxyNud1ySuVVCQRQ9bZ

So the question now is:
What is happening?
Is my computer compromised or is BTER in general in trouble?(I have submitted a ticket and I am waiting for answers)
I am using Two-Factor Authentication so I would be very surprised to conclude that it was my fault...

Have some of you identical experience?
Thoughts?

edit:
PS I forgot to mention that I had much more funds on BTER that particular time I lost these funds (0.5 BTC)... But they have been untouched  ???
