I was just about to reply to another thread about this, but I saw this one before I did.

I can't confirm if it's legit or not. I've been using it for like 60 days. I put in the minimum investment amount (1 mbtc) because that's all I had, and kind of forgot about it. The interest got to about 0.67mbtc and I deposited another 1 mbtc. In about two weeks, I should be able to get 1 mbtc in interest. Long and annoying I know, but it's all I can do for now. I'm hopeful it will work out and that eventually the only bitcoin I have invested are the coins I earned from this so I won't have to worry about mine.
