One of the use cases for a mining rig is as a heater. The problem with mining is that big companies are entering the race. Which means that mining will be even more difficult for the top currencies. 

I have written an article about the miners and bitcoin futures, you can check it [here](https://steemit.com/bitcoin/@ervinneb/the-importance-of-bitcoin-futures-for-bitcoin-mining)

Interesting article. Thank you for posting.

Some ideas about this: We have to consider that those information mean that Bitcoin Mining can really be eco-friendly.
We can use energy for heating and, at the same time, for crypto mining. Simply, the energy produced in mining is converted in heat (obviously) and - this is the point- the heart is used in recycled for heating houses. This is a very cool way to optimize energy-consumption processes.

Of course, we have to consider that for mining you use green energy or some energy surplus by traditional sources - so the eco-disaster is still a not-near possibility, because there is none clear effect on world energy production obtained by using traditional sources

❤Yes, it's a big energy consumption but what it will do is produce

very good news so people save money and the trees are not cut. global warming slows down

Nice. Thanks for sharing. There will definitely be a lot of innovation around optimizing these rigs if the technology sticks around.

This would basically mean that people could heat their homes for free due to the earnings they get from mining cryptocurrencies. That´d be just another awesome thing cryptos could do for us all :)

Man people make a big deal out of nothing.  They need to learn how things work.

The world is more environmentally friendly in terms of energy, albeit still heavily leaning towards fossil fuels, because of one thing: economics.  The price of solar and wind plummeted.

Just last week we had an article about a mining company converting their operations to hydro power.  Guess what happened, their profits went through the roof since their energy costs were almost entirely eliminated.

Who is the big country for bitcoin mining?  China.  Who has the biggest jump in solar installations the last two years? China.  

Even if the bitcoin code isnt changed to use less energy, with the advancement of renewable energies in terms of the cost, heavy power users are at the top of the list to switch.  This group would include bitcoin miners.  A couple years ago, it was google and facebook who were sucking all the energy the world had...now they are both nearing, if they havent attained, complete powering by renewables for all their servers.  

Environmentally friendly?  Yes...but it saves them a boatload of money.

I believe this is the future for POW coins. Either that, or solar tech improves considerably in price and efficiency to make POW sustainable over the long-term without the environmental damage.

Thanks for the info of Cryptocurrency @zer0hedge

This is fully informative post. Actually I haven't enough knowledge about cryptocurrency. A little bit learn form some blog.Your blog is one of them.Most of the time you writing about cryptocurrency. This is really helpful post for who are newly join here.Thank you very much to writing this matter.Please keep it up for us.

they are usually the same people who believe in welfare that increases per resource-consuming human-produced more subsidized rent, more free groceries, more electricity assistance, more monthly cash assistance and bigger child tax credits for maximum womb productivity, the more citizens and maybe doubled by this tax cut/tax welfare plan. They are also the ones yammering to developing countries that are still largely agricultural, leading to energy consumption far beyond Bitcoin mining.electricity consumed by a miner solely for electronic use , the total heat produced is determined entirely by the wattage of the device.

If energy supply isn't always a problem (paid fix power lease). I've got z97 sabertooth mom board, can maintain three cards. which will be the nice choice of cards? given the time now and uncertainty. I don't want to invest in the pleasant/most steeply-priced card. would really like to hear other seasoned's view in this. thanks @zer0hedge
