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
in my opinion ico without whitepaper is a scam, because usually before I invest in Ico or participation in the bounty I read the whitepaper first to find out all the information about the ico.
