Topic: Bitmain's Released Antminer S9, World's First 16nm Miner Ready to Order - page 110. (Read 531168 times)

Dudes are constantly posting this everywhere in the forums - is mining profitable in such and such an date on such and such a machine? Is an S9/741/GPU/CPU/Raspberry Pi profitable to mine on yesterday / today / tomorrow?

You can't do anything more than guess at mining revenues beyond a couple difficulty cycles anyway, so ROI calculation is pretty useless. Cost of electricity is far less important than the anticipated exchange rate of BTC at a certain time in the future - that is really the only metric that matters. I'm sure all those folks that have high power rates and talked themselves out of mining at a loss (or when the ROI was theoretically far into the future) back when BTC was $400 are kicking themselves now, because they were using the entirely wrong metric to calculate ROI.

Along with up front investment and operational costs, you have to have a target goal for the exchange price of BTC built into your calculations. When we setup our farm earlier this year, mining at the current price of BTC (about $ 1600) + the price of electricity looked pretty dubious on paper. But when we set a target price of $10,000/BTC for Fall of 2018, the notion became quite profitable in theory. Nothing like BTC has ever existed before, so that's all it can be - a theory.  Will that happen? Who knows. But it's every bit as plausible any any other metric we might have used, so we went for it.

ROI/profitability over any reasonable period of time is a figure you just can't calculate anyway. Do you believe in BTC? Any investment in BTC via mining or trading is speculation. You invest funds you can afford to loose based on the possibility of a future high return. Many years (or days lol!) from now when BTC is $35,000 or $350,000 you will be glad you saw beyond things like power costs or if you would get your money back on your mining equipment in six months, and if BTC is $0 then you really didn't loose that much relative to the potential gain and you'll have some great 1400w space heaters that have the upside of sounding like fighter jet engines on the tarmac. Heat the house and imagine you're Maverick from Top Gun.

Poor Goose.

The only thing for sure is the longer you wait around hand wringing about an unknowable variable like ROI, the less profit you are likely to make in the long run. Based on the information you can gather, what do YOU think (not someone else) is going to happen in the future? Trade on that and, win or loose, you'll always be OK.

It worth for me, basing on my calculations, but that all depends on how much your electricity costs now

Thanks for the info. Hopefully I can scoop at least one up in from the next batch.

Yeah there is no universal answer when it comes to the profitability..

That all depends on how cheap your power is, how fast the difficulty rises, and how much the price of BTC increases. You can use one of the many mining calculators out there to figure out if it would be profitable for you.

Is it worth buying S9 now ??

I would like to see some more availability on the S9s.

They haven't been offering discounts on recent batches. But when they do they are listed on the product page and are the ones tiny:

I wonder how much of a discount they offer if you buy 100..I've been thinking about contacting them and trying to come up with it. It would be much quicker ROI lol.

If you just buy below 100 pcs, dont bother to email or contact them. Just wait they launch another batch sales

Waiting periods for reply from suppliers are HUGE like from 1 to few weeks, there is no way that you will get an answer instantly, or answer at all if you are asking blunt questions. Best way to do is prepare money, and follow my suggestion in upper reply, that is best way how you can be informed when sale happens

I wanna buy S9 but , I sent mail and contact on website. But no one reply me ? Anyone know another hardware ?

Make twitter > follow them on twitter > turn on mobile/sms notifications > have prepared Bitcoin Cash in wallet to pay > when you get notification run to pc like madman > buy it > ? > wait 2 months > profit

They release each bacth every weeks, but some times in two weeks.

Hey I'm new here. From the US. I recently in the past few months have been researching. I would really like to get two s9's. Currently though I am in the same boat as Navigo. Not looking to pay double. How long are their normal intervals between batches? I'm leaning towards I will need to play the waiting game.

For the US I guess you can get some form the forum members, I wouldn't trust any other store as there are many many scams.
In Europe I had a similar problem, missing several batches from bitmain website. However on regular intervals they seem to release new batches (but with horribly long dispatch times), so if you can wait - you wait

I PM'd you.

I want to buy s9 and start my mining farm. When i started to search for the machine, it didn't take long to find out that the machine is out of stock everywhere and you can never buy one unless you are willing to pay 3 or 4 times more of bitmains's official price. I even started to look into l3+ and dashminer, but they are not any better at the moment. This very frustrating.

You and me both.  Bitmain has gotten used to being able to throw their weight around and abuse their customers and the market.  Would be ironic to see the same thing happen to them.  I know business isn't really the place to play nice but there is a way to beat all the competitors and still treat your customers well.

Man I'd love to see AMD/Intel/nVidia/MSI/Asus have a go at crushing bitmain.
