Thank you all for the advices and help guys, but Im not planning an ICO, my goal is to start straight with the product, bold a strong community and grow rather slow but steady. I think as most of you said signature and bounty campaigns will do a perfect job.
I cannot aim for great marketing mainly bcs of the funding but I think that if my idea is great, and the development is strong people who give me their trust will manage to do the marketing better. Im aiming for quality over quantity.
