Then again, are single use phone chargers any more ecologically horrifying than non-rechargeable AA batteries or have they simply been around for much longer and have become mundane.
I've got a battery bank integrated into my wallet anyway, so I won't be caught out.
Even now with that all being paper, I'm sure most of it goes to the trash and not to recycling because of how ripped up and soiled it gets.
Bitcoin mining consumes enormous amounts of electricity, which is why miners seek out locations that offer cheap energy. The Ordos mine was set up in 2014, making it China’s oldest large-scale bitcoin mining facility. Bitmain acquired it in 2015. It’s powered by electricity mostly from coal-fired power plants. Its daily electricity bill amounts to $39,000. Bitmain also operates other mines in China’s remote areas, like the mountainous Yunnan province in the south and the autonomous region of Xinjiang in the west.
Coal is a killer in China. Coal burning and the secondary effects of sulfate and nitrate contribute to almost half of the dangerous air pollutants in China's polluted cities, compared to 20% from car emissions.
Actually, it's 0.08% and rising. The energy for 1 transaction could power almost 6 U.S. homes for a full day.

Gold mining doesn't provide a useful service in return, huh?
As will_brown pointed out, Bitcoin isn't a necessary ingredient in smartphones, electronics, jewelry, medicine, dentistry, aerospace, glassmaking, like gold is.
Forget about US homes: How many homes in underdeveloped countries could one Bitcoin transaction power?
You're saying that because worldwide production of gold is so small and insignificant and practically useless compared to Bitcoin, and since only 5% is used for anything but bullion or jewelry, it doesn't matter and it's absolutely irrelevant to the discussion at hand that the smartphone and computer that you're using contains and depends on gold?
If not for gold, then how would you be communicating your strong confident words and impressive sounding but inaccurate numbers with us? Do you use bitcoin in your smartphone instead of gold?
Where did you get your "less than 0.01%" number and your gold-free smartphone? Is it made of clay?
Which yields 0.0148%. So you're right, not less than 0.01%, less than 0.015% instead. Still a far cry from 0.08$.
I would really like to know when have I said my smartphone was gold-free, how that is in any way relevant to the discussion anyway and not a completely inane pseudo-gotcha, I would like to know why you keep linking bitcoin mining to coal (another completely transparent appeal to emotion), I would like to know when have I said worldwide production of gold is insignificant... I would like to know all those things but from the tone of your confident lecture responding to points I didn't even make I conclude you're not really into discussing this. Intellectual dishonesty is more your thing, I presume.
And my point is that gold (of which, again, 95% is "useless" in the sense of not being destined to any practical application) costs on the order of ~1MWh per ounce to mine. At a yearly production of ~3000 metric tons that comes to 109TWh, almost an order of magnitude more than bitcoin.
How much is used by a single DuckDuckGo / Bing / Google search? Or Reddit post? Or email?
According to a 2009 post by Google: Together with other work performed before your search even starts (such as building the search index) this amounts to 0.0003 kWh of energy per search, or 1 kJ.

How much electricity does an American home use? In 2015, the average annual electricity consumption for a U.S. residential utility customer was 10,812 kilowatthours (kWh), an average of 901 kWh per month. Oct 18, 2016

So if "Electricity consumed per [Bitcoin] transaction (KWh)" is 173.00 kwh, and one Google search consumes 0.0003 kwh, then you can perform 173.00 / 0.0003 = 576,666.67 google searches (over half a million) per Bitcoin transaction.
If a house used 10812 / 365 = 29.62 kwh per day, then you can perform 29.62 / 0.0003 = 98,733.33 Google searches with the energy it takes to power a house for a day, or power the house for (24 * 60 * 60) / ((10812.0 / 365) / 0.0003) = 0.875 seconds with one Google search, if these gold-free clay tablets are as accurate as news reports say they are.
