I hope your post is a joke, if it isn't, then you're suffering from delusions of grandeur my friend. I also had ideas for e-games betting back in the late 90's, and doing the same for dota back when I first played it. "ideas" people like us are a dime a dozen, trust me. You're not a special as you think, neither am I.
Also if the idea I had is so common why dont i see it anywhere online? It wont be a generic wagering program like most esports betting websites, similar to firstblood.io but different in alot of ways
Because everyone with the same great ideas have one thing in common: lack of implementation. You'd be surprised how rarely ideas get implemented.
I can honestly tell you from business and life experience that if I came up with a great idea, I'd believe the programmer/implementer of the idea should receive 99% equity, and me 1%. That's literally how worthless ideas are, no matter how great they seem to you. Everyone has unique ideas. Everyone. Not sure what would be missing for you to not realize that so far in life, perhaps you're young?
