There is a difference between being pot-committed in poker and, being what you are, which is just delusional. Get your refund while you still can. I have seen this behavior many times from companies just before they go bankrupt. More frequent updates with more empty promises. BFL is likely going to become defunct after the large difficulty spike which is about to hit because more and more people will be demanding their money back. Even if they don't go bankrupt, your 30GH will be like pissing in the wind when it finally arrives. But odds are, your money is as good as gone if you don't request your refund because they will have to pay other creditors before you after the bankruptcy proceeding.
Interesting concept, suggesting a company that makes machines to product digital currency efficiently going bankrupt. Are you sure you have thought through the actual probability carefully before you posted? Downsize to suit what they want to mine, maybe, bankrupt, I doubt it.
Ah yes, I forgot! The fraud route is always an option, which their CEO is pretty familiar with having been convicted of it before. They could always fraudulently mine with customers' equipment before they go under in an attempt to save themselves. Good point, except for the fact that they are incapable of producing said equipment and it doesn't even EXIST.
