Do you trust more and ICO if they present a Minimum Product even if it has bugs? Do you look a the code repository before investing or you just look at ratings? You should not invest blindly!
I would preferred to have at least an MVP and much better if they have already a working product. The likes of MyCryptoBank, EOSex and Muusic.FM they have one thing in common they have a working product. If you gonna invest in some ICO's better choose the one who with real working product and developers with experienced in that industry.
