I agree with Substratum, they presented a nice vision but it seemed just a money grab. After the ICO they got themself a super nice office and half year later still no code. If you ask on their telegram about the stage of the product development you get banned, at least that happened to me.

At least I found another project with a similiar vision but that are able to deliver it. If you are also very interested in the concept then look at Oyster Shell, that seems like the real deal, what do you think about it?
