I deposited $650 in Btc to bitcoinfog during the day yesterday when they werent down. I submitted for a withdrawal. Now on the blockchain it shows that my money went in, and came out(to what should have been my localbitcoins account) but I havent received it to my LBC account. Blockchain shows it was relayed by the btc address's that the Fog uses for anonymity but it seems my money is gone. Only time will tell as they are down still....
They will use a different address to send bitcoin from then the address that you deposited to. This is done to make it difficult to trace where specific bitoin came from that have gone through there mixing service. If you are able to trace the route of your bitcoin then they are not doing a very good job
