I have $125 coupons I can't even use on shitmains website. Checkout says I don't have any coupons even tho they are listed in my settings. I emailed them twice over a week ago and still no response. What good are coupons if you can't use them?

Last week ROI on an S9 purchased on shitmain's website was slightly less than a year at .10/kWh. Today, it's over 400 days which essentially means never as difficulty is still rising and bitcoin is still falling. At this rate, it won't even pay to turn on an S9. I guess all the manufacturers pushed their prices high up so they could squeeze the last bit of profit from us miners before the crash.

I don't know how you're running the numbers, but they're wrong. First of all the ROI of an S9 is not anywhere near as long as 400 days, even with bitcoin doing so poorly recently, so that says something right there, that it can keep being profitable even in this environment. Second of all - assuming the difficulty keeps rising and the price of bitcoin keeps falling - yes, the S9 would not make a good investment. However the truth of the matter is that you can't see the future any more or less than the rest of us. You don't know if the price of bitcoin will keep falling, or if it will rise, or what the difficulty will do, etc. If you believe in bitcoin and believe it will make a comeback (which history tells us it will), then you don't base your numbers off today, but what you expect them to be in the future, especially with something as volatile as bitcoin.

Hello, my name is Brady and I'm working on building a GPU farm and was looking to see if I could get some help. I'm going to be making rigs that would have at max 19 GTX 1080ti's on a ASUS B250 mining board, in one unit (assuming that this would be the most cost-efficient rig to build) and was looking to see how many rigs with these specs could run off a 30 amp breaker, or if we would need to put in a higher output breaker (assuming that the power is 120votts of AC).

Maybe Bitmain knew about the drop in crypto coins and wanted to sell off all of the S9's at higher prices....would be very very cheap now if they kept it pegged to BCH/BCC.

This is wishful thinking. BTC value cannot be forecast but you can make some pretty good predictions about total network hashrate and difficulty, I’ve shared mine on various occasions in this thread and even the best case scenarios don’t show an S9 to be a good investment currently, worst case scenario shows the S9 to be money down the drain. It’s been over a month since I built those forecast and so far the total network hashrate is growing even faster than my original worst case scenario. That should tell you something. Anyway, you can find the work a few pages back in this thread, check it out.

You can bank on difficulty rising. Even if btc price goes back to 20k, its a stretch to ever roi on a newly purchased s9

With the price of bitcoin down 57% in one month and difficulty on the rise, the S9 still pays itself off in 7.4 months, and you want to sit there and tell me that even if the price goes back to 20k it would be a stretch to ever roi? Are you and everyone else who keeps saying this on drugs?

7.4 months with no diff adj factored. Its not hard math man. It's going down much faster than people realize.( profitibilty) 10-15% loss per month, compounding.
Could things change? Yes sure. China miners could die off for a month or two, all miners with high costs could shut off, and a few other factors.
Diff going up is a fairly constant thing for the next little bit, and an s9 purchased for march delivery will get smoked on roi-ability, even with free electric.

You really shouldn't say stuff like this, if you aren't careful someone might believe you even though you are 100% wrong. People used to say that about the s7s all the time. An s7 at 10c power was profitable until about 3 days ago....the s9 will be making money for a long time to come.

Stop buying industrial miners, running them at home, and then complaining about the noise.

It's not like offering FA, or investment advice of any sort. Profitable versus ever returning investment money IS NOT THE SAME THING. Spending ~2.5k and waiting till march is more or less an absolutely horrible idea.

Lets see, first u cant say it is going to be 15% per month on avg, if u look at difficulty charts bitcoin has been flat for months or raising 4% 2% 1%, also if u look at the hashrate chart we are down from 6 days ago. I recommend you compare Hashrate history with price history and look at times of price correction like these how difficulty of mining reacted. https://bitinfocharts.com/comparison/bitcoin%20cash-hashrate.htmlThe factor isnt china miners moving it is simply price raise, if the difficulty keeps raising and price doesnt a lot of hash power is going offline. As it is A LOT of S7 must be going offline, in fact Bitmain announced a new miner that must ppl say is a bunch of S7 they are moving Some ppl will say miners will keep mining by having faith that btc price will raise, but thats not really true, must mining farms wont make decisiones based on faith they will make sound business decisions and running at a loss isnt a way to run a business they will simply halt operations and cut costs while they wait. We are not talking about cents, an electricity bill from a big mining farm can get really expensive Me personally i have 6 coming on march ill probably sell them for 3.5k but that is because i expect a new antminer soon maybe other asics...

I don't know where you are getting 7.5 months from to ROI. An S9 with PSU and shipping and customs fees is going to run about $2600. Or were you going to run the S9 with free air? Are you getting free shipping from Bitmain too? As of right now BTC is below $6500 so according to coinwarez with power at 0.10/kWh the ROI is 504.5 days. So I'm not making my numbers up, maybe you are.

Are you and everyone else who keeps saying this on drugs?
I'm sorry but if all you are doing is looking at the online mining profitability calculators or you're just projecting your earnings today forward to estimate what your miner will earn you over the next 224 days, your are (and I'll say this as nice as I can) letting yourself be mislead. When I had my S9 running in December (I sold it since then), those online calculators were telling me it would make me about 1 BTC/year. Now if I enter the numbers it's less than half that! That is because the total network hashrate has doubled since then. If you don't understand the significance of this you should look up the Legend of the Ambalappuzha Paal Payasam. And guess what, it will almost certainly do so again, at faster and faster rates! How do I know this you ask? Well I don't know this for certain, it's an estimated guess purely based on the fact that THAT's WHAT IT HAS ALWAYS DONE! So you can say we're on drugs for saying what we're saying but you're the one betting against the network hashrate doing what it has always done. Look at the forecast tables I created, I posted them a few pages back, they show you exactly what is likely to occur and what that will mean for your earnings (and beware, at the time BTC was $11500). At the current

People used to say that about the s7s all the time. An s7 at 10c power was profitable until about 3 days ago....the s9 will be making money for a long time to come.
First of all it's about ROI, not profitability, Yes an S9 that is running now and has already paid for itself will be profitable for a little while longer, however, buying an S9 now is silly, the numbers just do not show they will ever ROI based on current network growth rate. And if an S7 was "profitable" (not ROI'ing) until recently but now it's not anymore, that should tell you something shouldn't it? How much you earn from your miner is determined by the miner's hashrate vs. the total network hashrate. An S9's hashrate is about 2.8 times that of an S9, that means that the total network hashrate has to just get multiplied by 2.8 for an S9 also to become unprofitable. As I mentioned in the post above, the network hashrate has doubled in the last 2 months, and it is growing even faster now, much faster. So how long do you think an S9 will remain profitable for? Just do the math!

What if the price of BTC will be $30k be the end of the year? Means the $400 I made from machine this month will be $2k? "Do the math!" lol

"Do the math!" lol Yep, but under that scenario you're still better investing the money you pay for a miner directly into bitcoin now, if all you're banking on is BTC value to go up. In a year's time you'll be left with more BTC (valued at $30k), You do the math, how much BTC can you buy now for the price of a miner? Will it make that much BTC this year? The answer should be obvious.
