If you have a team then start researching about your service or product. I think then you may have to create a whitepaper and prepare your team for the upcoming stages.
A marketing team yes.
In addition to marketing and development teams, an ICO should also have potential future products, such as products on health, energy, finance, and more. And then this will be a consideration for investors to participate in the project. In fact, ICO will succeed if token sales reach hard cap. This is just an ordinary suggestion from me.
Thanks! what do you think is a good number of tokens? It's not easy to make an actual estimate about how many tokens people will buy from the ICO.
