Personally , I don't think there should be an ICO without whitepaper. The whitepaper bridges the gap between an investor and a company. Can we say a ICO without a whitepaper is a scam? Or what can you say about an ICO without whitepaper
Having an ICO without a whitepaper is a major flaw in the cryptocurrency world of business. A good whitepaper is a sign that the project has foundation and background and it allows the investor the opportunity to go through it so as to have a good and detail understanding of the project.
