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
Whitepaper is very important in blockchain projects especially ones that intend to embark on ICO, any ICO without whitepaper gives out the impression of them being a scam
