I think ICOs are a necessity for your project. Something big needs a good team to develop it. by yourself you will not be able to make your ideas go far. Implementing an ICO will make you more responsible. You will need to have a good sales and marketing team who will help you a lot in the future. Then there will be investors and if the project is successful you will soon become rich. 
How should I find a sales and marketing team.
Although I have written the core technology in the white paper, most people will not read it.I haven't found anyone who really understands it yet.
Although I have implemented and core functions, the code is also on github, but there are fewer people watching.
