Is that a jocke ?
2 btc?
Check your math dude. In Feb diff which is unknown since something big is happening behind the scene not more that 1 BTC and i doubt even at that price it will ever make roi

Any way Bitmain is a smart businessmen with a good record which deserves our respect . I wish all of us the customers to be at least half the smart compared to him
Besides CNY is knocking at the door and that is only time for most of the pople to meet their families. I would not blame China DHL or EMS employees if they mess up something with some orders and this get delivered in march. For sure Bitmain will do his part and provide all of his customers with tracking as promised
PS: the picture in most optimistic scenario

0.8 BTC loss at least for 2.2 BTC invested
Your numbers don't match your claim.
I updated them (changed the difficulty to the 2.07B estimate for the next jump, changed power to 360W, and removed the BTC/USD increase, changed the lower diff increase/jump to 5%)

Even with those changes that calculator is showing break even in June, with difficult 11x higher than the next jump at 22B

You forgot that there is at least 1 diff jump before those get to mining. I would love to buy more of those, but those are just too pricey for the risk. 1.5 BTC I could manage.
