Not sure if you're a troll...
I'm not going to list the common traits, because they're all more or less identical.
More or less identical? So both use Namecheap and have a WhoisGuard email address? Turns out that Namecheap is a very large hosting provider and that it actually accepts BTC for payments. You'll find a lot of BTC-related websites to be hosted there. Hardly a surprise. And WhoisGuard? That's an anti-spam feature offered by Namecheap, to prevent a users real email address from showing up in these whois-queries. You'd be a fool not to use it's available.
It sounds like planning ahead to me... planning ahead a ponzi
How about you look up what "a ponzi" means. It seems be a trend to just throw around words without any regard for their actual meaning. Even if your accusations are true, this whole affair isn't anything like a ponzi scheme.
