That's what I thought, too, at first. I looked at their website and saw the Fertilizer (sp?) and that it was a dead project. Why would they still promote it on their website?
Because the devs are busy with Stratis (my hunch)
You can bet the CEO of Stratis would not mention BlitzCash several times (and that it will be the first sidechain) if he wasn't 100% sure about Blitzcash. It's too much of a risk to leave up to some anonymous devs with a coin and an out-dated website. There are too many scam coins to take the risk.
And the only way to be 100% sure about a coin that has a website like BlitzCash is to secretly be the ones behind it. In my onion, it's both a side project of Stratis, and a side chain of Stratis.
That's what I reason, at least.
But all coins are speculation, not an investment.
