Think again. $40k gets you 5 TH delivered next week. By the time you get the Neptunes, difficulty will be much higher. 5 TH now is far more profitable than 12 TH several months from now.
5th next week? Who sells them?
25+ Antminers from Bitmain.
https://www.bitmaintech.com/product.htm3th of Antminers = 5kw (by taking 300watts per Antminer) = 31.654
BTC (without shipping) = 25.8k $
3th of Neptunes = 2.5kw = 14.6
BTC = 12k $
Two times more $$$ and watts for the same hash-power.
There is a really big difference here. You really can't even get a Neptune for at least another several months so why even compare right now?
All my friends requested refunds also for their Neptunes. In the bunch I think there was like 18 of them. Don't be surprised if you see some go on sale or we hear some news from KNC now. Once they see their very loyal customer base is dumping them out I'm pretty sure we'll eventually hear some thing from them soon. They only have one spokesperson here who isn't a sales person and can't really confirm on anything since all decisions are made by Sam. Only a matter of time we'll hear something. Once you are a millionaire and see possible money that could be yours leaving your bank account it starts to make you worry, no matter how much you have.
