Topic: Worth it ? (Read 1071 times)
thanks all for helping , well i think with all the risks and the noise / heat i think i'll something else to profit , thanks again for helping <3
A couple of items of note:
As described in the OP, the efficiency figure is off by a factor of 10. The stated value is .98W/GH. The actual figure for the S9 is .098 W/GH. Big difference.
For the past 2-3 years the life of miner wasn't actually it's functional life, but it's economically useful life. A miner from 2 years ago could still be 100 functional, but might well consume more in electrical costs, than it produces in BTC, each and every day.
The S9 is presently the most efficient miner, and may well remain so for a year or more. That's kind of unusual in the Bitcoin mining realm. The major risks associated with buying an S9 today:
1) The price of BTC could decline. That will increase the time it takes to pay off the original cost of the miner.
2) The difficulty could, and probably will, increase which reduces your effective BTC production rate per day. This again increases your time to pay off the miner.
3) You could run into hardware problems which will cost something to correct. The original Bitmain warranty is 90 days. I don't know what it will be from the Amazon seller, almost certainly less than 90 days.
The short summary is that you should read about Bitcoin mining, including difficulty adjustment and such. Once you are better informed, and have figured out your cost of electricity to run it, and found a place to run a hot (think heater), loud (think hair dryer on full blast), all the time (think 24 hours per day), then you can decide if you want to spend about $2700 to purchase and run S9. Oh, and don't forget the cost of a power supply and shipping for both.

Why would want to pay almost $700 more than what Bitmain charges for them? "free shipping" from the Amazon seller sounds nice but - shipping from Shenzhen to the USA is only around $140 so buying direct is still cheaper.
Not to mention with buying direct from Bitmain you have a warranty with them (I know some will knock it but at least it's something). Add the warranty direct with them instead of a 3rd party and a HUGE profit reseller's added in I cant see why anyone would buy it off Amazon. Pay like 1/3 more? Just seems like way to assure ROI is even harder to make.
The good thing is if OP is thinking of using fiat he might reach ROI quicker depending on what BTC does. But he can go fiat to BTC to buying from bitmain, which I would do over amazon.
But to know if it's worth it OP what is your electricity price? Also can you handle heat/noise as it is a big miner?
If Bitcoins price stays around $100 of what it is now,over a year to ROI.(ROI=return of investment)
If Bitcoin difficulty stays where it is,over a year to ROI.
If Bitcoin doubles,you could ROI much sooner.
If Bitcoin difficulty drops,you could ROI much sooner.
If your electricity is free,you could ROI much sooner.
If Bitcoin difficulty rises (as I think it will),you may not ROI at all.
If Bitcoin prices drop,you may not ROI at all.
If your Bitcoin miner burns up,you may not ROI at all.

i definitely not buying it from amazon i'm just showing you the exact model 
as for the electricity it's showing is this image in AED ... 1usd = 3.67AED

my main question is : how long it'll last before it's too difficult to profit ? thanks

i'm thinking about buying a 13TH/s miner @ .98w/ghs for $2,700
It's a good thing you provided enough information to discover the mistake, because paying for a 0.98W/GH miner is actually pretty stupid.
Also, paying more than probably about $1000 for an S9 is a bad decision. I know the going price is twice that, but the going price is stupid.
You need to take into account any import duty when buying direct from bitmain. You may be lucky and not pay anything but take it into account 
Why would want to pay almost $700 more than what Bitmain charges for them? "free shipping" from the Amazon seller sounds nice but - shipping from Shenzhen to the USA is only around $140 so buying direct is still cheaper.
That's the newest miner bitmain have released so you should get some profit out of it (dependant on your electricity cost).
Hello ,
i'm thinking about buying a 13TH/s miner @ .98w/ghs for $2,700
so is it worth it
i mean how many years it'll last before it's too hard to mine bitcoin @ the wattage level ?
and lets say after a year i buy another one will it make a different or it'll be stupid ?

and if you can link me a good power supply for this ty
