I just came accross btcunion.com which offers 0.15% interest per hour which sounds extraordinarily high. According to the site, it opened only 2 weeks ago. Has anyone had any experience with this site? Please also suggest some legit bitcoin investment sites. Thanks.
So 3.6%/day , right?
That's called HYIP bro . Where you deposit a bulk of your money to get a few of cent of your money.

Better to stay away , where offers interest per hour , they will collapse soon.
