I have an idea, but... should I do it Open source?

Hi All,

I have an idea that I think would be really good in the e-commerce world, I have been trying and failing to build this on my own over the last few years. I am now thinking to make it opensource, as a way to get it out and get help on it. Also maybe it will help me grow as a developer and learn. The only thing I am worried about is that I will lose the ability to make money on this further down the line. Am I being silly?

Would love everyone's feedback.

I draw inspiration from reactioncommerce, they seem to be doing well as an opensource e-commerce solution.
