That's called tumbling and bter.com would not scam someone over $150. Be patient.
The problem is that after the deposit to the BTER deposit address, it got sent to two other addresses from there (seen on blockchain explorer). That's what worries me.
Same here. In my case more than 2 BTC. I'm really worried about it. I've sent a ticket and support told me they made the deposit, but it still doesn't appear. I see the direction and it's been deposited in 2 other addresses...
