Re: [Antminer S1 open for sale again] The last round before the Chinese New Year

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

I rember the times when people was paying 2btc per USB stick and no one make a rio in btc from mining alone
Any way they are two much factors to be unpredicted but I wish too all customers to make rio I
Happy mining

LOL... Yeah, but everyone knew that going in. Those USB sticks weren't going to break eveb for years even with free power and no change in difficulty. This is different, even with reasonable hashrate increases they should break even by the summer, and you still have the hardware in hand when that happens.
They're good reason to not buy these (turning your BTC into hardware to mine back the BTC drastically reduces your liquidity) but they're nowhere near the dogs that the AM sticks and blades were at introduction.
