Actually that's make me wonder too about their million of transactions per second, I mean it's too unrealistic and I won't believe it until they have some eta that the investors can try for themselves. The availability of the product is a plus and edge in every ICO, it's hard to invest to something that you can't try or see. IMO, I'm gonna look at this project for further development.
Of course, as an investor, you will try to look at all sides but if they can prove that they can really implement that, we are going to see Credits as the next big thing in the cryptocurrency industry it will zoom to the top 10 in the position but right now there's uncertainty.
Honestly, I heard it like 100 times last year that this or that project will replace ETH or be in the TOP 10. This is all useless talking. Hardly any project has delivered so far so why should especially this one do. Don't get me wrong, I like it as well but as long as it doesn't work on a main net it remains as "optimistic promise".
You phrased it very fairly and comprehensibly. It is exactly the way I see it. As long as no project replaces ETH it's just talking bullcrap for advertisement reasons and nothing more.
