Yes, the site is down, as I had expected it would be sooner or later. The 'legit' company registration was probably a clever cover or decoy tactic.
I am concerned that this could form the template for a series of scams in the near future.
A 'legit' company suddenly appears, starts to offers freebies and generates interest on forums, has a fairly well designed and legit-looking website.
Accepts payment only by bitcoin, then, one day, 'poofff'... gone, just like that. Too late, by the time you realise everything was just a cover for a clever scam!
I think, at least partly, it is the unique nature of bitcoin transactions makes such a scam possible.
Hereafter, I would be extremely careful dealing with a site that "accepts payment only by bitcoin"!
If I was to contemplate ever doing this again I'd now have to not only check their Domain Record information against what's on their website (as far as possible) making sure to quiz the 'company' about any discrepancies BUT ALSO, and just as importantly IMO, run diagnostics on their email header information just to be certain!
Gosh, seriously ? Yes, emphatically Yes 100%
