Re: ETH mining in Germany with Innosilicon A11 Pro

Thanks all for the answers! Small update on the costs: I managed to get 0.05 EUR kWh electricity costs from a nearby company. But still, I guess ETH is not worth it to mine, but what about BTC? If I buy antminer S19 pro, which are still available for about 8-10k EUR, I could make a decent profit as passive income per year at such low kWh costs. What do you think?

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.

Let's just see what happens if the difficulty would jump to 30T before I have payed back my investment:
(((((550.000.000.000.000* 6.25 * 600 * 65535) / 2^48) / 30.000.000.000.000) * 6 * 24) * 0.99) *365 = 0.83 BTC/year

For the yearly electricity costs:
17Kw * 24h * 365 days * 0.05€/kwh = 7,5k€

So basically, if I estimate what the bitcoin price would be in 1 year, for instance 50k multiply this with 0.83, then substract 7500€ I'll see how much income I have made. Now I have to see if this income is sufficient to pay back my initial costs for mining hardware. According to my calculations I would make 34k EUR in one year if the BTC price goes up to 50k again as well as the Diff to 30k. I think it all depends on the BTC price, because if the initial investment for hardware costs are 60k and I only make 34k profit per year, I need almost two years to breakeven. Does this calculation make sense for you?

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€.

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.

So I asked the CEO and the company uses 84mio kWh per year and they get electricity costs of 0.3-0.4 kWh EUR, even better than 0.05 kWh
