Ok guys ! I have (I think) an excellent decentralized app project in my mind. Is there a dedicated place on the forum where I can try to find people to get involved into this 
Why not just submit it here ? If you want to find the interested developer/investors this is kinda the right place.Again,I hope the project isn't just another ICO with shitty tokens. Cryptos are not my job and among my friends it hard to find people involved in blockchain and crypto.
So any good advice for me please ?
I like the initiate you are taking even though you really aren't into cryptos.It's very hard to find people who would work on your idea for free.You need to have a lot of money or skills to make the project come live.Unfortunately you don't.So any good advice for me please ?
