Still a working option, but still not what we would like. I'm sure you can find something better.
Lol, this is the best thing that can be now, fast, easy, and most importantly, safe!
Has anyone here used similar services? I would like someone to share their experience with me.

I once used the services of Bit3-mining, I confess, it was a very good experience, I managed to make good money. Also, my entire social circle is very concerned about the situation of the environment and I hid for a long time that I have farms. But thanks to this service, I stopped hiding, because Bit3 uses only 100% cheap and environmentally friendly hydropower from power plants in Norway and Canada to create bitcoins. It was a lifesaver in that regard.

I dare say that in many situations, an aircon running on heating would be a better heater than an old miner, because of typical COP, eg. using 1000 watts to do the same amount of heating as a 3000w fan heater / oil heater / miner. Not to mention floor space usage / noise.
Eg. a miner that's 96 TH/s, 2400 watts, 1.5% pool fee, would lose about $3.14/day @ $0.15/kwh power cost, compared to a small aircon using say 800 watts to pump 2400 watts running 24/7 would cost about $2.88/day (of course if your aircon never stops running, it's undersized.)

Modest/excess wattage spent on lotto mining sounds good.

Depends on the use case. I am sitting in the back room of my condo with a 1 board S9 at the moment keeping the temp here above 72f [22c] BUT since I have 1 zone heat I get to keep the rest of the place at 66f [19c] I just have 1 zone heat / aircon for here so although a lot less efficient, it is cheaper to run.

In the bedroom I have a 2 board 400w give or take L3 running on a LTC / Doge lotto pool. So far got a few doge blocks over the last couple of winters. But when I am sleeping I am not heating the rest of the place.

I rotate through old miners depending on what is working and if I have sold any over time.

How much BTC are you making per one week of leaving it on?  What pool do you use?

It's not on all the time, depending on the outside temperature and a few other things it's on at most 1/3 of the day.
Figure it's generating about $0.30 a week on ViaPool BUT it's not for generating money. It's about spending less money on heat.
300 Watts is 300 Watts I can turn it into heat with a space heater or I can turn the same 300 Watts into heat and a few cents. By the end of the winter I can buy myself a lunch.

With the LTC / Doge lottery pool I would have been better just PPS mining somewhere, but it's not as much'fun'

I have some AntMiners S7's and below.  

I have not used them for two years.

I used to use the Bitcoincash guy's site but not sure going to use them again.

Any ideas on good exchanges for older miners?   I'm using them in winter for primarily a heat source.   I figure it will cut down a bit from full price of heat.  
You can use https://Bestbuy.com and also https://Amazon.com to sell this Antminer. Beacsue I think that now Antminer S7 is useless to mine crypto. As you are saying that for heat purpose, I think jester would be better cause it uses so much electricity.
And also if you have cheaper electricity ⚡ than you can use it for heating purpose too.


People don't seem to have learned that electricity is the same for any electronic device or a heater per amount of heat generated.

The same amount of electricity is used per degree of temperature increase.

Our company (SafeTek Solutions) is currently looking for LARGE amounts of broken/unwanted/obsolete/scrap mining servers/equipment.

If you happen to come across a lot that fits the bill, please let me know.

I personally would like to use old Antminers for heat in the winter time lol

since I have few amps and I don't make big purchases I usually buy on ebay.

then, living in Italy, I would still pay quite high customs fees if I had to buy large quantities from China.

I also live in Italy. Cheapest way to buy them is through some addresses in Switzerland (Lugano).

S9 for $50? I can never find them at that price. 4 months ago I paid $200 for it and currently the prices I see around are more or less those.

It depends on where you get them from in the first place, but $200 does not make sense, it is a rip off, you paid 14.5$ per th for an S9, you can get m21s for close to half that rate.

You can get M21s in China for 7.5$ per th ( this is todays price list)

It has been awhile since i requested S9 prices, but if you need help sourcing them in China and your order qty is large enough i can arrange for you.

With free power and free miners more or less. Even assuming my time was 100% free, just the cost of getting cheap internet would kill any potential money that these miners would make.

Get an LTE connection, even 3G would do, you can mine with a 1-2mbps connection just fine, regardless of how many gears you have -- you could always use a proxy.

OP>

I think last I checked Antminer S9 was going for like $50 with a PSU, since your miners are an order of magnitude less efficient, I think they won't sell above $10 so anyone who can't pick them up locally would probably refuse to get them even for free.

Of course, this might not last forever, in the previous bull market people sold their S9s for $500-600 (they were as cheap as they are today in the 2019 bear market), so if BTC ever recovered to those levels, S9 would probably be at $200-300 and your gears might be worth something again.

  So  I have heard older asics have been used to keep a steady load on bigger diesel generator setups in different parts of the world. One example was a mine in alaska and a friend. That worked in Africa at an airfield to repair airplanes. They had expensive generators and very efficient air conditioners. But at peak times had to run  aircompressor ,drain pumps ect .. and at night alot of lights. They would use the load of the asics to prevent burning out the gennys. But the mindset was different the mtx ran them for load and did not take care of them, like for example rain getting sucked in they were just plugged in and run inefficiently, they did have network cables on them.  Btw the way the whole conversation started was he was showing pics they had a meal kitchen place setup and low and behold there was what looked like the case of an s9 stripped out on end with a teapot on top.

There are several spots on my land like these, they all run old devices. Does it pay off? No. Of course not. But if every solar powered device which is not connected to the grid would produce some GH insstead of heat when not being used, it would be awesome and a great step towards decentralisation of mining (again).

How are you getting bandwidth to all these things? Wi-Fi? 4g? and how are you powering that equipment? Or is everything hard wired?

I use raspberries with a GSM module and IoT-cards with 500 GB prepaid. Also one GSM-router, but this is pretty shaky.

I agree - for the moment. One solution would be to have a multisig-wallets for hundreds of small miners (like: Three trusted members would administrate this wallet). If all these small miners would send their hashes to one pool, the payout could take place once a year and then being distributed to lightning wallets. Still, it most probably wouldn't pay the costs, but at least the minimum payout of some pools could be eliminated this way.

In the best of all worlds - we don't live in one - all micro-miners could pool and solo-mine...

I have frequently looked at some places that I can use that have more power then they can use, and at least this time of year could use the extra heat of a miner, but the issue turns into I don't have internet there and would have to get some reliable internet there to mine.

Well, you can just set it up for solo mining on a pool solo.ckpool.org if you use it for heating anyway, then why not try to try your luck, maybe it will smile on you, just read here: https://bitcointalksearch.org/topic/yh-solockpoolorg-2-fee-solo-mining-256-blocks-solved-5237323

If it's using 1/5th the amount of electricity, surely you're seeing a decrease in hashing rates.
Strange enough: That's not the case. It hashes happily on all its ASICS with the normal hashrate.

I use solar as well and I can say that I think sending the overproduced energy to your electric company in order to receive a credit has to be better than just burning the electricity.  You could probably pay to run your actual heater with the saved funds and be more comfortable and have more money.  Not trying to discourage you, but for $0.04 a day you're probably better off solo mining with that thing and hoping to hit the lottery.  That at least has the possibility of getting you a return.  I think everyone else would agree though, you're better off just turning that thing off unless you need heat and your heater is broken or something.

I - partly - agree with you. My setting is, though, a bit different.

Overproduction from the roof goes to the electricity grid and I get paid for it. The mining thingies are decentralized. For example: My tractor's generator is defect. Instead of replacing it, I put a solar panel as roof on the tractor. It loads the battery. Once the battery is full, energy goes to a raspi with a SIM card. The raspi is connected to a little pod (50 GH/s).

Then I have a cave under my house. Two solar panels are producing electricity and first filling two batteries. Once full, the solar power is running a dehumidifier which collects the water to a barrel. Once the barrel is full, a pump - powered by solar energy - pumps the water to a cistern. Now all excess power goes into two old Bitmain S1 which hash with crappy 160 GH/s. Their heat is funneld into the cave for condensation. The water goes - you guess it - into the barrel, too. The excess heat is directed out of the cave again.

Then there is a solar loading station for my electric lawn mower. Once its batteries are full, the power goes - you guess it - into mining.

There are several spots on my land like these, they all run old devices. Does it pay off? No. Of course not. But if every solar powered device which is not connected to the grid would produce some GH insstead of heat when not being used, it would be awesome and a great step towards decentralisation of mining (again).
