I won't invest in any ICO without a prototype. The risk of being scammed is well too high. How many ICO's don't even have a MVP ? More or less 90% ?
With a prototype, we can expect the team to manage and fully develop the product described in the whitepaper.
Before ICO's, every startup that encountered the success would have developed a high quality product. The product was tested by the public and now ?

Even project has beta product like KICKICO, AirToken, the price of token from these projects are also dump to below the ICO price until today.
Therefore, so difficult to know the potential and the power of the community in the ICO projects.
As long as the whale want to dump the price of ICO token, they can control and dump the price anyway.
