A quiet S7 would be a great thing.
the problem is now that there is no competition, the S7 is sold at a price of $1823 USD or 7.5 BTC, the real price if BTC goes up is in BTC, and if BTC goes down it is in dollars.
If BTC goes over $300 dollars, the $1823 will go up, most likely over $2000, and if BTC goes down then the $1823 stays, unless if it goes down a lot, the miner price will not proportionally goes down.
The pricing scheme seems to be calculated at an amount you will never ROI.
https://bitcoinwisdom.com/bitcoin/calculatorThis calculator takes into consideration difficulty increases.
at a 10% difficulty increase ( 20% is the default) and free electricity you will not ROI in over 530 days, and will end up 1.7 BTC short or ROI.
at a 5% difficulty increase and free electricity, it takes 296 days to break even.
Let compute the fair price of an S7, using difficulty increase of 10%, and 15cents per kilowatt, and a ROI of 3 months:
you will make 1.2 BTC, loss of 6.3 BTC.
lets use difficulty of 5%, and 10cents the killowat, for 6 monts:
3.5 BTC made, 7.5 expended, loss of 4 BTC.
Using this calculations it can be seen that the S7 will never ROI, and it is extremely overpriced, more than double what it should cost.
from a hardware point of view it is nice, but it does not help if it will never ROI, I would personally buy a few if it was priced at a price in which I could ROI, or even break even in 6 month, but the fact is that I will not even break even at 2 years.
Do not believe me? use the calculator yourself and plug in the numbers, even with free electricity you will not ROI.
Most likely price will go down, since few are buying, the item has not sold out in many days, but Bitmain has to seriously stop being greedy and lower the price by at least 60% if we are expected to have the opportunity of at least reaching ROI.
I am hoping that BTC doubles in price, but that will not help, since if BTC doubles in price, Bitmain will double the price of the miner.
The real price drop will be soon, and that is when the block halves, there will be a huge market of used bitcoin mining equipment, that will make all prices new or used hardware to drop, I am personally waiting for that day, or the day in which I can get hardware that will ROI in about 4 to 6 months at most.
