Seems the concept is good, but I doubt you will get a direct investor from here. But yes, most likely you would get contributors for your project who would help you to move up. So, your concept is a peer-to-peer exchange, and centralized exchange, the concern is many similar existing platforms exist on the market. Make sure users will get a few new features on your exchange and that would be a good reason to use it as well. I have seen the same exchange but unfortunately, they failed to gain the market.
Thanks for the comments, in regards to investors the option is open. I do agree that contributors are easier to get from here, having that said contributors do play a big role especially at this stage.
I am working on bringing new features, they wont be features out of the blue but more of solutions to existing issues in crypto exchanges.
Update: New python developer joined as partner. Still looking for another dev to join. If anyone is interested send me a pm.
