I deposited 0.1 BTC 1 week ago to my https://adbit.biz account, and still they have not credited my account.
Their support and email is not replying, so I think this is very obvious scam.
Hmm. That seems.. like a stupid thing to do? Could you link your transaction ID?
Also, i think it's worth mentioning that you shouldn't have used adbit.biz in the first place, due to the fact that they accept fake traffic. Regardless of whether or not they credit your balance, they're still scammers for doing so.
Their top website on which they have banners is:
http://lumina.tin.vn/ This site has an alexa of 1 million, no HTTPS, and a layout that dates back to 2009, with no relevant content.
Yet:
It receives over 3000 clicks on their ads daily? Whut?
