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 don't think an ICO without whitepaper absolutely means that it is a scam, although of course the majority are. It is mostly to say that with or without whitepaper an ICO can be a scam. However, there are promising ICO's that publish their whitepaper later. If you think that the ICO in question is promising then it inquire with the devs, ask them the question about the whitepaper
