It has no sense to do ICO in two blockchains. Really look like just PR. I think it's scam
I think that's a little bit unfair to call them that. They are based in the US, and it is really hard to exit scam for a US company, and I don't think those guys want to go to prison. Also, they already have an alpha demo at demo.qchain.co. How many other blockchain startups even have a demo?
Anyway, I think it's smart to go for two blockchains. Hard to predict where the tech is going to go, or whether even NEM or ETH can survive, if, say, GoogleChain or AmazonChain comes along. Best to stay blockchain open and blockchain agnostic, and Qchain is focusing on building a product that can plug into multiple interfaces.
