In a project everything must be prepared.
2. Funds must be prepared because building a project must have funds. Do not rely on funds from the sale of ICO / IEO. It will be difficult if the project does not develop.
I just wanna say that it is true, an start up must have enough resource to develop their projects but better to not make ICO to be the only main resource. They should build their capital structure as good as they can do. Having an rational proportion between issuing stocks and obligation to fund their project is very important.
