1) You never see them before either photos or videos
2) Have you check their company background?
3) You are paying by bitcoin only
Bitcentury has disclosed quite a bit of information about themselves that is good, but the Problem is bitfury. You are dealing at the mercy of bitfury and metabank/asic...
I presume "them" and "their" are metabank/bitfury?
We may have some good news regarding this in a few weeks, just don't expect pictures and videos, at least not until we are active in Russia when boards are announced for delivery by Metabank. I can only tell you we are working crazy hours in the background to ensure this entire operation is as successful as possible, your boards depend on it, and so does our future as a business. It is my understanding that next week, will be the moment of truth for the Bitfury ASIC. It will be very impressive if he gets it right on his first try. We're all standing by with bated breath!
As for paying only with bitcoin, well, it's what this is all about in the first place, so that's a good thing. I mean, for a lot of people it really is about migrating away from fiat; but I think perhaps what you are alluding to is that it is not reversable if something goes wrong (i.e. fraud). On that, I can only comment that apparently Metabank has been operating as a bitcoin buy/sell service since supposedly 2011, so we should have *some* faith at minimum.
