I also managed to enter a second address to Bitminer, so I messed that up. The rate they show for a free account does seem too good to be true, so I'm interested if anyone got paid. I think Startminer looked like an identical scheme, so I hope they do pay you.
I've found Moondoge to be fairly good as I can get a few cents from it each week with very little effort.
I'm not ready to invest more at the moment, so I'll stick with Eobot and see how it goes. It's all just a bit of fun
