Minersbox (formerly Minerscube) looks like a total scam. Don't give your coins to scammers.

It should not be confused with ASICMiner Cube, which is a real product.

When you are buying mining hardware please remember that most offers are scams. Most mining hardware "companies" are scams. Not a few. Most. The safe route is to buy from companies that have delivered in the past and where the customers have been happy. If you pre-order from a company that has never delivered anything before, then you have to be very careful and do some research. Most of those are scams, remember?

If their WHOIS listing is anonymous ("privacy protect", "whois guard", etc), their website has no contact information, their machines are faster than all competitors, their machines use a fraction of the electricity of competing products, their prices are way too low, their webpage has a paypal logo but they don't actually accept paypal payments (see their FAQ), their emails to potential customers (which you can read elsewhere on bitcointalk) reveal that they don't know which proof-of-work algorithm bitcoin uses, they don't seem to understand what an ASIC is, and they give some crazy stories to explain the other suspicious aspects..... add all this up and you should realize it's a scam. Not just a scam, but a poorly presented scam by an inexperienced con man.

Even if you wanted to get scammed, there are better ASIC scams out there.
