It is a lot more feasible with 6 cents that's for sure, this rate is the average for the industry and thus your chances of making a profit increased by a few orders of magnitude, what I don't like about this business plan is the S19 pro part, it's way overpriced and since you can get 6 cents per Kwh that is sort of an edge which you have to make use of, people with free power buy T9+ which is about 10$/th, those with 1-2 cents buy S9s which costs about 14$/th today, so paying $10,000 for S19 pro at a cost of $90/th is without a doubt a terrible idea, let's just make a simple assumption that whatever the ROI that shows now is going to be shifted by 50%.

S19 pro ROI = 10,000/ 770 = 13 months * 1.5 = 19 months > terrible.
M20s (used) ROI =3500 / 390 = 9 months * 1.5 = 13 months > bad.
T17 (used)  ROI = 1700/ 250 = 6.5 months *1.5 = 10 months > not so bad.

*These are based on 6 cents Khw, prices in China + 300-500$ for shipping and duties, the T17 is a terrible gear, it was just there in the reseller list I got recently so I used it

But you get the point I suppose.

Of course, you can go to as low as S9, ROI will be $300/60 = 5 months * 1.5 = 7.5 months, but then it will be a bit risky because if the price drops a bit of difficulty goes up a bit that 60 bucks will disappear and you will start losing, unlike the S19 pro which has a ton of room for profit, these are some of things you need to consider, there is no right or wrong about it, it all depends on your risk management.

Other important factors such as failure are also important, investing 10k in a single gear means that if one hash board is dead, you lose about 3k worth, investing in 3k gear you only lose 1k worth, of course investing in 10k gears means less work and easier management, but everything comes at a cost.

Also, the availability of mining gears in your country is very important, for example, if you want to be in the mid-range risk and go with say M20s, but then find out it will cost you 7k instead of 3.5k, then the S19 pro will be a lot better, if you get lucky and find S9i/S9js for 200$ then ROI is only 5 months and thus might be worth taking the risk, I can't tell you what gears to buy ( don't buy any 17 series from Bitmain because they have high failure rate).

The 1.5 factor isn't something you can count on, it's just a speculation, if your risk tolerance is strict, make it a factor of 2, if you are a risk-taker, you can just work with a factor of 1, there is really no perfect model that fits everyone, I can't tell you what to buy and when to buy, but I hope I gave you the key points which you need to consider before entering the business.

Okay, I get your first point. But, first of all I already have a company and second the electricity costs are not scam. I get the electricity costs from the company of my father, who only pays 0.05 kWh EUR (thanks to good contracts with the energy provider, since his company uses a lot of energy per year). Regarding the taxes: the Htax factor in my county is 300%, meaning that if I make 38k Eur in profit I have to pay 7765€ Einkommensteuer (personal income tax) + 1417€ Gewerbesteuer (commercial tax), which makes 9182€ in total taxes paid after one year and would still leaves a profit of about 20-30k EUR IF Diff goes back to 30k and the BTC price only increases to 50k. Last part confirms your first statement of ROI = 3 years.

Is there a limit on how MUCH of that .05 EUR/Kwh is available at the location you chose? How about cooling at that location? How about noise produced by the miners at that location? Is there Internet access available? I would expect that with five S19 Pro you'll need wiring for at least 20 Kilowatts of electricity.

I ask these questions since I didn't see anything about the TYPE of business (Industrial, Office, Manufacturing, etc) that might have problems supporting a mining operation.

ROI for the s19 is 3 or more years if you buy it for 8 - 10k. Innosilicon ETH miner is also not worth the money. Your problem is, you think it is so easy to get your money back, but you will only buy ASIC for horrible price. You must also pay tax in germany -> you must register a company and so on.
And again your electric price is not possible in germany -> if you get 0.05 cent than it is scam -> in our company we need 500 000 kwh in 1 year and our price is with all taxes, EEG and so is 0,22€.

Aber ich glaube kaum das du dann auch diesen günstigen Strom bekommen würdest, schon gar nicht wenn man neu auf dem Markt kommt.
Naja und das die Nachbarfirma die dann eine Leitung rüber schmeißt denke ich wird auch nicht passieren zumal du ja eine Menge und wirklich eine Menge Strom verbrennen wirst.

und wo gibts in deutschland 5cent all in? abgesehen man ist kraftwerkbesitzer...

Regarding BTC hashrate, keep this in mind. Currently the hashrate is lower than usual because of China banning bitcoin miners. So many miners shut down their farms and are either relocating their farms or just selling them off to other people.

So what this means is that the previous ATH hashrate will most likely return in the near future. Because those ASICs are still profitable and someone, somewhere will buy them and turn them on again.

So you need to run your calculations on a higher difficulty has a the one that we had a few months back.

If it's a good deal in Germany, you might want to figure out a way to sell that power you generate, but with 19 cents kWh you can't possibly profit from mining.



Price can go both ways for years, the difficulty only goes up in the long run (facts are in the charts), your profit will decrease every month more often than not, all these online calculators are misleading, people who bought S19 pro 6 months ago were also looking at a 1 year ROI, it's now still 1 year ROI, they are not even remotely close to ROI.


Where did you get that 65k from? you said S19 pro, today it costs 8.8k in China, so without tax or shipping it's already 70k, with tax, shipping, wiring, and whatnot you will be closer to a 100k than 65k, and no, 8 S19 pro will not make you 2.4 BTC in one year, you have better chances to walk on the moon than making 2.4 BTC with 8 S19 pro in a year.



This is investment advice, and telling you to go for it ( like the first post which is terrible advice) or not, isn't something anyone should do, but if you ask it in a different way, you might get an answer, if I were you, I would NOT go for it.

There are a dozen topics that discuss mining vs buying bitcoin vs keeping your money in the bank, just search the forum and you will find many, some folks who usually never owned mining gear might tell you to invest, most of the folks who know how mining actually works in terms of business - will tell you you should not even think about it.

I am 100% sure you will end up losing money? of course not, but it's an easy bet, you are more likely to lose money than not, I'd say it's easily 20% vs 80%, I would be very surprised if you end up making a profit.

See mining isn't like other businesses where you can expect an increase in demand, if you start a coffee shop tomorrow, you are likely going to benefit from the increasing demand for coffee, more people grow up and want coffee, so the competition factor is not so huge, with mining, however, the rewards are fixed, and they only go down in time, so the competition factor is everything, then comes the question, who are you competing with?

You are competing against people who

1- Have FREE power
2- Very cheap power rate
3- Access to cheap mining gears
4- Pay no tax on income
5- Pay no tax on import
6- Pay $5 an hour for a certified electrician 
7- Pay $3 an hour for someone to install/maintain the miners

And the list goes on and on, every point here counts, these points are like the weapons you take with you to the battle, the more the better, being in Germany you don't have access to cheap gears, you have to pay import and income tax, you can't hire an electrician for $5 an hour, you are going to war with your bare hands, the odds of winning are extremely low.

Ich habe mir jetzt nicht die Mühe gemacht deine Werte in die Berechnung bei whattomine.com einzugeben denn die jetzige angezeigte Profitabilität ist trügerisch.
Die aktuelle Difficulty sollte bei deinen Überlegungen keine Rolle spielen. Es gab auf Grund des Mining-Ban in China einen großen Drop in der Hashrate des Netzwerks und dadurch eine sehr große Anpassung der Schwierigkeit nach unten. Vermutlich wird es nochmals etwas runter gehen am Wochenende, aber langfristig wird der alte Wert ziemlich schnell zurück kommen sobald die Miner Ihrer Geräte an einem neuen Standort wieder in Betrieb nehmen und dann wird es halt wieder langsam immer weiter steigen wie vorher auch.
Schau dir einfach mal die Charts an...

First where you get 0,16€ for the kWh in germany? Is not possible.
Second 0,16€ is to much when we go in the real bear market like the last 3 years. You need under 0,05€ to get profit in bear market -> not possible because the EEG only costs 0,065€.

Think green and buy an enerkite to produce your own electricity 

You put some number in a online calculator , and based on that what you saw there, you think its worth to start a mining business to mine zcash and BTC with GPU ? with a electricity price of 0.16 EUR kWh OMG ...
Please do a little bit more research on this dig just a little bit deeper

First , please read my post from 2017 , there is a lot of useful information there , especially about mining calculators
MY Post from 2017 is HERE

After you read that few line there , there is another good reading for you from 2021 , with some updated information
Updated Info 2021;)

I wrote as an answer to one of the duplicates of this thread, but OP didn't want to listen.
It's not only that 16 eurocents is expensive; it's also that the calculations made now, while the difficulty is temporarily low, which may easily mislead him.

I'm not a specialist here, but i did have a quick glance at your table.

What i'm concerned about is that your worst case scenario isn't what i would pick as a worst case scenario...
Also, i don't see your power bill into this picture, everything is calculated in USD and EUR, so it's very hard for me to see if you included this factor into your calculation.

You do have a scenario where your diff increases to 25T, but you couple it with a 47% price increase.
You also have scenario's with a price decrease, but you couple it to a "mild" difficulty inrease.
And you don't take into account those antminers tend to break quite often and only have a 3 month warranty (if you buy them brand new).

Also, i started searching for place where you could buy an S19 pro. They weren't sold by bitmain anymore (apparently), and the few seamingly reputable stores that still had them in stock asked prices ranging from 8000€ to 15000€/piece. I'm not sure if you'd be able to buy 8 S19 pro's + cables + shelves + network + PSU + A/C + import tax + S&H for 56.000€

Now, for what it's worth, i would probably go for a different "worst case" scenario:
8 miners * 8000 € =64.000 €
21% import tax = 13.000€
S&H, shelves, PSU's, cables, A/C, fans, switches,... = 5000€
fixing machines, keeping the running for > 2 years, replacing broken ASIC's = 15000€

total hardware cost =~ €100k

total power draw = 26 Kw

total hashrate = 880 Th/s

Difficulty => we know there's enough hardware out there to push the diff back up to 25T. We also know the year prior to China's decision, the difficulty had an increase of ~7T in one year. Since your ROI will defenately be more than 1 year, i'd go for an average difficulty of 30T. You have to realize the odds are pretty big that turned off hardware falls into the hands of somebody mining at a much cheaper power rate than you, and this person will probably buy thousands of second hand units making the price he pays per unit a lot cheaper than you buying 8 or 10 units.

Price => Eventough the price might rise (it's actually very probable), we're making a worst case scenario here... The current price is ~$32k, but the price has drastically decreased in the past aswell... so let's assume the bottom price is €20k in >2 years

Let's see our income in one year, with a writeoff for your hardware of 2 years :
Hardware costs: €50k
Power costs: 26Kw * 24h * 365 days * 0.16€/kwh = ~€36,5k
Total cost: €86,5k

Income @ 880Th, 30T diff, including a 1% pool fee:
(((((Hashrate (hashes/sec) * average block reward * 600 * 65535) / 2^48) / Difficulty) * 6 * 24) * 0.99) *365
(((((880.000.000.000.000* 6.25 * 600 * 65535) / 2^48) / 30.000.000.000.000) * 6 * 24) * 0.99) *365 = 1.33 BTC/year

That's an income of ~€26k/year. That's not enough to pay your electricity costs...


Now, once again: this is my worst case scenario... It's a little far fetched, but not impossible...
