Topic: What would you do with 20 kWh of free power? (Read 486 times)

Thanks for letting me know. I have opened a thread here: https://bitcointalksearch.org/topic/mining-with-20kwh-of-free-power-5253727.

The way the forum is setup any non btc mining for any other coin belongs in the alt coin section.

https://bitcointalk.org/index.php?board=160.0

I have a thread there https://bitcointalksearch.org/topic/number-9-ninth-altcoin-thread-back-to-the-moon-baby-5144362

Try to keep this all BTC mining.

You have an interesting question/thread going. for the BTC angle alone.

Personally I do both asic and non asic.  Which I would discuss in detail in the alt coin sections.

Assuming you have 20/6 or 20/5 meaning 3.33 to 4.0 kwatts.  doing a little of both is okay.

But We should discuss it in alt coins.

As alt coins  section will allow a btc asic to  "other coin- other gear " comparison discussion.

Thanks to both of you for the infos gathered so far.

I was also considering the option of GPU mining, according to whattomine an AMD Radeon VII would be generating 70Mh/s on Ethash (ETH) using 220W per board giving a profit of $1.55/day, so getting x6 of those GPU's would be giving a rough $9.3/day profit with usage of 1320W and producing 420Mh/s, so isn't it actually a good choice? I compared it to the AntMiner E3 which produces 180Mh/s using 800W, compared to the same hashrate of those x6 GPUs, I would need 2 ASICs, so to produce 360Mh/s I'd be using 1600W, at this point I'm 'spending' more energy to run the ASIC than what I profit if I compare both of them.

I couldn't find any offers yet on the antminer E3 however, basing an hypotetical cost of $1500 of the ASIC I'd be ROI in about 10 months, while GPUs would cost me $4800 average (based on new board price) with a ROI of 20 months (if I did calculations correct), while GPU's have a longer ROI than ASICs, I'd be able to run more of those GPU's investing back the profit given during time (due to low power usage compared to ASIC).

Are my calculations right? So in the long run, aren't GPU's a better choice than ASIC? And also, what do you think about the new antminer Z15 which is advertised with a ROI of 80 days? ($17 per day profit), scam?

Also I am based on Europe, Italy. Here the power cost is one of the highest, reaching an average of minimum $0.22/kWh and maximum of $0.32/kWh, so mining was never profitable no matter what, that's why I actually never invested on it before. Now with that chance of solar implant, the matter changes, as I'm not paying anymore.

well  if he is in usa he should get cheap s9 gear.

I think he is in asia not usa.

here are 2 modded s9 units.

about 11 th at 900 watts very quiet

Phil has you in the right direction. Your setup requires cheap hardware(Asics) efficiency doesn't matter just power draw and remaining within that. I don't know what a Whatsminer M10 sells for but that could be another option maybe even 2 at LPM depending on what you can grab. You just need to balance cost against hashrate to decide what is best for the runs you will be able to make.

The short answer is it's hard for you to not be profitable in the long run regardless, as you are not paying for your electricity costs. There is always the potential your gear breaks down adding to it's overall costs but in the longterm you will likely be ahead. You could even look at it this way, the 10% extra you receive (110% from government) could cover the cost of your hardware.

Check the Forum Marketplace for used gear people are unloading and if all else fails start to look at manufacturers for some sale prices.

lets say you live right smack on the equator.

12 hours of sun never rains. magic as it always rains a bit.

you have 12 hours of night.

so divide by 2 not 5 correct?

no because first hour and last hour of sun are on a shit angle.

so divide by 3  right

no.  clouds rain etc.

so divide 4 right   giving you an average of six hours full sun ☀️. the best locations on earth with tracking panels do this.

divide by 5 is more likly  correct. for you.  maybe 6.

take your 20k in panels and your year round numbers will almost always be 3.33 kwatts to 4.0 kwatts non stop.

this is a grid tied setup.

now you can go about it with cheaper gear.
a used s9 makes 14 x 9 = 1.26 you could run 2 for sure.

earn 2.56 a day you can buy them for about 70 to 💯.

in 100 days they may earn back 200 to 256.

since you have some solar you could go the route of cheap s9s.

i am usa based and i recently sold some modded quiet s9s. less noise low power .

look at my post for the last few days you can find my info on them.

they are cheaper way to start.

The solar costed me zero, it is a government issued offer. It's a legislation in which they reimburse 110% of everything you pay to build the implant up to $60k in a timeframe of 5years, however, you can give up this credit to the agency installator and they install it for free, including the panels costs and everything else. However, as a binding by contract, I won't be able to sell the exceeding energy out of consumption, I'll be forced to give it to the public net for free, so lets say i consume 3kWh for my house, 17kWh is unused and go lost. Atm I have 56panels of 360W each (20.160W total), do you think it's possible to make some profit out of those? I won't expect full power 365 days per year, as that's impossible, there is rainy days, cloudy, etc, so let's say I expect an average of 13-15kWh instead of 20.

What I am aiming for, is to run a couple of hardwares leaving enough to store energy on batteries for the night, however, I've no idea how much that would be profitable or worth to do. Because, let's say I have to pay 1.5k usd to generate 6$ a day, that would means I need 8 months to get back those 1.5k, and on a btc market, that will never happen I suppose, as it fluctuate a lot and if it goes down, I just lost moneys by the hardware cost. Are my calculations correct?

Also, why 20kWh needs to be divided by a factor of 5 or more? Aren't the panels max power (so, in my case, 360W per panel aren't full 360W)?

20kwh needs to be divided by a factor of 5 or 6

so if it is grid tied.  it means you have 20/5= 4kwatts 24/7/365. at best. to maybe 20/6 = 3.33 kwatts 24/7/365

So you could run a whatsminer m20s. 24 hours a day

that is 68 x 9 = 612 us pennies or $6.12 a day.

so what did the solar cost you ?
a m20s is about 1500 usd.

I recently had an offer on my country, and I'll be able to install a 20kWh solar panel implant, and on my head ringed the idea: What if I get some mining rigs or ASIC to mine bitcoin with that, since I won't be paying anything on power consumption?

So the main question, is it still actually profitable to mine BTC or any other crypto?

Considering my setup of 20kWh power for free, what you guys would do?

I've been searching around on google looking for resources, documentation and so on, but being myself a beginner, and never mined before, I ran into some topics discussing about how ASIC's are just a scam and you won't even recover the invested prices of the ASIC itself, or stuffs like that.

What you guys suggest me to do? And, the more important question, how much that 20kWh implant is gonna profit, if there is any profit at all?

I am a beginner, so I welcome all kind of help and informations, thanks!
