To be honest, these concepts were made multiple times before (BitMit, Coingig, Cryptothrift) but few succeeded because of the complexity of such system to run stable on 15000+ users.
I was learning about Bitcoin and came up with this idea myself, and then did research and I indeed concluded there were multiple attempts and sites that have this concept.
No idea was stolen, and everyone is free to work out ideas? Idea's can't be patented or trademarked.
I was working on a similar site for a community member then they up and dissapeared. just odd timing is all, but i'll know right away whether any of the code is mine.
First time I hear about it, first time I meet you and I can tell you for sure, the site is made from scratch by me and my designer (who did the design and graphics).
