'Bitcoin Could Cost Us Our Clean-Energy Future' (grist.org)

An anonymous reader shares an article: Bitcoin wasn't intended to be an investment instrument. Its creators envisioned it as a replacement for money itself -- a decentralized, secure, anonymous method for transferring value between people. But what they might not have accounted for is how much of an energy suck the computer network behind bitcoin could one day become. Simply put, bitcoin is slowing the effort to achieve a rapid transition away from fossil fuels. What's more, this is just the beginning. Given its rapidly growing climate footprint, bitcoin is a malignant development, and it's getting worse. Digital financial transactions come with a real-world price: The tremendous growth of cryptocurrencies has created an exponential demand for computing power. As bitcoin grows, the math problems computers must solve to make more bitcoin (a process called "mining") get more and more difficult -- a wrinkle designed to control the currency's supply. Today, each bitcoin transaction requires the same amount of energy used to power nine homes in the U.S. for one day. And miners are constantly installing more and faster computers. Already, the aggregate computing power of the bitcoin network is nearly 100,000 times larger than the world's 500 fastest supercomputers combined. The total energy use of this web of hardware is huge -- an estimated 31 terawatt-hours per year. More than 150 individual countries in the world consume less energy annually. And that power-hungry network is currently increasing its energy use every day by about 450 gigawatt-hours, roughly the same amount of electricity the entire country of Haiti uses in a year.

Our heat pump has kept our house toasty through the coldest Vermont winters, and it does not use a resistive element. If the temperature drops below -17, it just shuts off until it rises again; in that case you would need to either make up the heat loss with a resistive element, or just coast through it.

It's only anonymous until a person can be linked to a ledger entry, and then it's the least anonymous way in the world to transfer wealth.

I'm sure the original coder was well aware of that and didn't worry about it because they never expected it to grow beyond a small circle of friends using it for shits and giggles. Or not.

    Come again? I don't even understand what the unit of measure you're proposing means, but I can already tell you that if you want to understand the cost of transactions, we don't measure them "per $1,000 equivalent". We measure them per transaction.

    According to these researchers, each Bitcoin transaction currently costs the equivalent of 9 days worth of energy for an average US household, with that number growing over time as more resources are added to the system. The average US household consumed 10,766 kWh annually in 2016, which we'll assume hasn't shifted much in the last year. The average residential price was 13.30 cents/kWh in September, which we'll assume is comparable to today. Taken together, they suggest that the average US household pays about $1431.878 annually for electricity, or about $3.92/day. As such, a single Bitcoin transaction currently costs the world $35.28 in electricity to process. Other places put the current cost closer to $72-77 per transaction.

    In contrast, the cost to process a cash transaction is the amount of time it takes someone to recognize that the dollar bill is now in the seller's hand instead of mine. Or, put differently, effectively zero. That's why we can use cash to purchase everything from a stick of gum to an entire estate.

    From those numbers, we can say a few things:
    1) Bitcoin is (currently) unviable for small transactions. In fact, if you look at the average transaction value, you'll see that it correlates to the average transaction fee, suggesting that as fees go up, the system becomes unusable for day-to-day purchases, making it unsuitable as a cash replacement. A system only works as a cash replacement when it is capable of scaling from our smallest purchases to our largest purchases while maintaining a cost per transaction that is FAR less than the value of the transaction.

    2) Transaction fees don't cover transaction costs. Note that the fees listed in that last chart are far lower than the costs listed in the earlier chart. This is an example of an externalized cost (and explains how the system can work contrary to your claim that it can't work any other way), where someone else is paying for something you're doing. In the case of Bitcoin, it's the miners who are paying the remainder of the costs for each transaction (i.e. their electric bills), but they're paying those electric bills in USD, EUR, GBP, and similar currencies, rather than BTC, which means that their electric bills don't track with fluctuations in the value of BTC. This isn't a problem when BTC valuations are high, since additional miners join in to take advantage of the imbalance (this is more or less a form of arbitrage, exchanging cheap electricity for more valuable BTC). Unfortunately, when BTC valuations slide against the other currencies this becomes a major problem for those miners. Their rigs become sunk costs that are incapable of producing a return on their value and can only be sold for a fraction of what they cost.

    3) Transaction costs can exceed their benefits. If you want to buy $15 in groceries and are told every transaction has a $75 fee to confirm your purchase, you won't buy those groceries. You'll wait until you need a lot more before you make the purchase. That's both a good thing (the system discourages wasteful activity) and a bad thing (why are small transactions wasteful in the first place?). If, however, you're told that the cost to confirm the transaction is merely $7.50, you

    With transaction fees over $20, there is no reason to use Bitcoin for anything other than speculation.

    Bitcoin was designed so that individuals and their computers did the mining. Instead we have mining performed by exotic and expensive ASIC hardware that it under the control of only a few.

    If this site is still News For Nerds (and not Echo Chamber For Morons), then there won't be a single person here who didn't see that logical conclusion coming from the very start.
