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
I think it is impossible to impose a good project without the presence of whitepapers. Having whitepaper is very important for all investors and also bounty participants because it is not only the bridge between the project and investors rather it is language which is used both them to communicate and to understand what is the projects all about. Probably we should say a project without whitepapers is definitely a big scam so don't make any investment with this kind of ICO.
