ok the only trustable guys I have found are
www.bizingit.com they offer a messily 6.5% Per annum account, but interest is calculated daily so its really 6.95% per annum
but here's the kick in the guts the account minimum needs to be $5000 USD which is way to steep and they base the value and payment of interest of all accounts on the USD and not bitcoin which means if bitcoin skyrockets your left with a guaranteed 7% profit so theoretically you could lose bitcoins by investing with these guys

a good start but im sure others could do better
Yeah, really trustable guys. The domain expired a few days ago. Pls do not post this kind of junk anymore.
