This is an example of the blockchain deposit someone posted to btc-arbs.com that they never received..

https://blockchain.info/address/1MWdD9ATRvqU1d5AhoreSe7dtPweVUtVY3

Now look at the (two) blockchain addresses someone (assuming btc-arbs) had transferred those funds out to,

https://blockchain.info/address/1NGNtqtnqnfEn5KmxftrS3huGbZQfzB9cj 0.1471 BTC

https://blockchain.info/address/18jLitCJzdhx4EXBAPRj1vX2bgsePFNN3U .0018 BTC

Under 1NGNtqtnqnfEn5KmxftrS3huGbZQfzB9cj of the .1471 BTC address, you can see all of the withdraws are mBTC amount, which looks like mBTC very similar to the amounts that are being moved from the Legacy account to the each Users Balance account at the end of each day. Not to mention the recent consisent same ROI.

If anyone wants to match up their receiving deposit address for those that HAD successful btc withdraws, then this wll prove my theory.

In summary, they are paying out people's ROI each day with new BTC being deposited into the site. Which is why people who recently deposited BTC aren't getting their Balance on their account and explain why some are getting sucessfull withdraws when their BTC is moved from the Legacy account.

Anyways that's my two cents.. I hope it helps those that went big with this site. I'm sorry to hear all those that can't withdraw their BTC
