Ian Welsh hat geschrieben:Bitcoin was also a libertarian project. Libertarians hate inflationary money, so Bitcoin was made deliberately deflationary. There are a limited amount of bitcoins which can be created. There is a strong first mover advantage even without the fact that bitcoin is acting more like stock in a company than money.

Deflationary money is reactionary. It rewards people for being first, not for being productive. It encourages people not to spend and not to invest in something other than money, which is bad for economies. Moderate inflation, contra-gold bugs and Austrians, is a good thing, as it devalues effort from the past. It’s great that you did something wonderful 40 years ago, but what you do today should matter more.

It shouldn’t matter completely more, I’m not saying that retired people shouldn’t be able to eat and pay rent, but it should discount and discount more and more over time.

People who won the past shouldn’t control the future for all that long. People who are winning the present should, if anyone should.

Power Compare hat geschrieben:Bitcoin Mining Now Consuming More Electricity Than 159 Countries Including Ireland & Most Countries In Africa

The map above shows which countries consume less electricity than the amount consumed by global bitcoin mining

[...]

According to Digiconomist’s Bitcoin Energy Consumption Index, as of Monday November 20th, 2017 Bitcoin’s current estimated annual electricity consumption stands at 29.05TWh.

That’s the equivalent of 0.13% of total global electricity consumption. While that may not sound like a lot, it means Bitcoin mining is now using more electricity than 159 individual countries (as you can see from the map above). More than Ireland or Nigeria.

If Bitcoin miners were a country they’d rank 61st in the world in terms of electricity consumption.

Here are a few other interesting facts about Bitcoin mining and electricity consumption:

• In the past month alone, Bitcoin mining electricity consumption is estimated to have increased by 29.98%
• If it keeps increasing at this rate, Bitcoin mining will consume all the world’s electricity by February 2020.
• Estimated annualised global mining revenues: $7.2 billion USD (£5.4 billion)
• Estimated global mining costs: $1.5 billion USD (£1.1 billion)
• Number of Americans who could be powered by bitcoin mining: 2.4 million (more than the population of Houston)
• Number of Britons who could be powered by bitcoin mining: 6.1 million (more than the population of Birmingham, Leeds, Sheffield, Manchester, Bradford, Liverpool, Bristol, Croydon,
• Coventry, Leicester & Nottingham combined)
• Bitcoin Mining consumes more electricity than 12 US states (Alaska, Hawaii, Idaho, Maine, Montana, New Hampshire, New Mexico, North Dakota, Rhode Island, South Dakota, Vermont and Wyoming)

[...]

While Bitcoin Mining is only currently consuming 0.13% of the world’s electricity output, it’s growing incredibly quickly.

The Bitcoin Energy Consumption Index estimates consumption has increased by 29.98% over the past month. If that growth rate were to continue, and countries did not add any new power generating capacity, Bitcoin mining would:

• Be greater than UK electricity consumption by October 2018 (309 TWh)
• Be greater than US electricity consumption by July 2019 (3,913 TWh)
• Consume all the world’s electricity by February 2020. (21,776 TWh)

The Cost of Mining Bitcoins

The Bitcoin Energy Consumption Index estimates that the total annual cost of mining Bitcoins stands at $1.5 billion (£1.1 billion).

However, that assumes Bitcoin mining is occurring in places with cheap electricity (not an unreasonable assumption).

The US average retail price per kilowatthour is 10.41 cents, which means using 28.05 TWh would cost: $3.02 billion (£2.28 billion).

In the UK it would even more expensive, assuming you paid the rock bottom price of 10.10 pence per kilowatthour (Bulb’s prices for London homes) it would still cost £2.93 billion ($3.89 billion).

Interestingly, Bitcoin’s price increase over the last month has been just over 40%, which is greater than the increase in electricity consumption.

This means the estimated annualised global mining revenues now stand at $7.2 billion USD (£5.4 billion), which even at the more expensive estimates listed above, means it’s still very profitable.

The Motley Fool Singapore hat geschrieben:When you consider that bitcoin doesn’t take up any physical space — it exists only in digital form — the high cost of custody and storage is mind-blowing. Based on regulatory filings, SPDR Gold Trust (NYSEMKT:GLD) historically paid about 0.08% of the value of its gold for storage and custody services on behalf of its shareholders, or approximately $1.04 per ounce, per year. In contrast, Coinbase’s custody solution costs 15 times more.
