Why would you spend money on filling a DC with older gen chips especially when you will receive the newer chips with MUCH better efficiency beats me. You either have money to burn or you will simply build a new DC for the newer chips or you simply pay so little to do this that you can afford to replace everything in 1-2 months. I can understand filling just a part of it for tests, but a whole DC...something doesn't adds up.
So I will order 50Th-100Th the first day the miners are announced, if they arrive to me before April 1 I will pay you 1 BTC but if they do not then you send me 1 BTC.
How does that sound?
That was a very bad bet from my point of view. You just made a bet with a manufacturer who can simply get this in time by liaising with a 3rd party who can sell a small number of miners. Maybe the miners will be built by BitFury and just sold by the 3rd party company just to win that bet.
