There's a hidden cost of trust there, though, which vanishes with bitcoin (or at least reduces its cost). Maybe the value of bitcoin is more apparent from the perspective of venezuela at the moment, where the risk involved with traditional banks, currency, and security is more apparent.

I am emphatically not taking a stance on which I prefer here, I might add, just pointing out that there are more variables here than you're acknowledging.

With fiat, I at least have some idea who I am trusting, and if my trust is betrayed, I have some idea who to work with others to organize to work to inflict punishment. And, the people involved are aware of that.

With crypto, I have to trust an anonymous network of people that I have only distant and indirect indications aren't, in overwhelming majority, mutually cooperating agents of a single potentially adverse party, and no idea of who to go after if my trust is betrayed. And the people involved know that, too.

Yes, except the trust is free. Bitcoin replaces that trust with burning electricity.

It's kind of like standing on the ground. The surface of the Earth stops you from accelerating under gravity for free. But if you want to hover just above it, you have to burn ungodly amounts of energy, because you're now replacing surface with active propulsion. This is the same relationship as Bitcoin has with trust.

And yes, flying is occasionally useful. So are trustless systems. But both the ground and trust are features that cut out a lot of unnecessary energy usage from our lives.

Re:Bitcoin Gold Hit by Double Spend Attack, Exchanges Lose M... by gamblor956 on Wednesday May 23, 2018 @06:23PM (#17138938)
Bitcoin and other cryptocurrencies require even more trust than normal currency. With a normal currency transaction, you need only trust at most 2 other entities entities: your counterpart to the transaction and the government issuing the currency.

With a blockchain, you still need to trust the counterparty, but now you also need to trust that the coders have properly designed and programmed the system, and that the miners either don't have the power to corrupt the system or aren't corrupt, and you need to trust whatever exchange you use to get into and out of the cryptocurrency.

Plus, you've added in a significant amount of time--at a minimum 20x the time with Bitcoin and significant transaction fees that as a practical matter have exceeded card interchange fees by 2x or more for the past 3 years straight.

Your right about their being more variables...with cryptocurrency.

Re:Bitcoin Gold Hit by Double Spend Attack, Exchanges Lose M... by drb91 on Wednesday May 23, 2018 @06:33PM (#17139032)
I think there are fundamentally different ways we're talking about trust: you "only" need to trust a government, you "only" need to trust a bank, vs trusting a certain proportion of miners to be following the same bitcoin specs you are, as well as trusting that people will value it tomorrow. Both of bitcoin and government-issued currency requires trust, and building that trust is fundamentally difficult, depending on your needs, and comes with tradeoffs. It seems like you're only acknowledging one end of these tradeoffs.

One obvious tradeoff you're not considering is that of a criminal getting its assets frozen, for instance. There are less black and white situations where you might prefer bitcoin as well, if you have a little imagination. If you could address that, I'd probably appreciate your comments more.

You forgot to calculate how much (in resources) it costed to build all those banks and vaults and how much it costs to run and maintain, globally.
Re:Bitcoin Gold Hit by Double Spend Attack, Exchanges Lose M... by gamblor956 on Wednesday May 23, 2018 @07:31PM (#17139439)
It probably cost a few billion dollars to build all those banks globally. It costs a few hundred million to maintain all those banks and vaults. However, these banks and vaults can handle more than 2000x the transactions of Bitcoin in a single day (Visa on its own is 750x the capacity of Bitcoin, and Mastercard handles about twice the number of transactions as Visa), so Bitcoin would need to be at least 1/2000th the price to build and maintain the network to maintain a comparative economic advantage against just those two companies. Including the entire financial system, Bitcoin would need to be somewhere in the neighborhood of 20,000x cheaper and more efficient.

And since we're taking into account all of the underlying systemic costs going into banks, we need to do the same for Bitcoin. That means including all of the power utilities, factories, and mining facilities that went into making the hardware, plus the cost of shipping the hardware worldwide, plus the cost of the utilities and transmission lines needed to operate the network. And that's clearly not 1/20,000th the cost or resource usage of our current financial system.

There are ~8000 banks in the US alone, around 15K around the world.

According to your made up number, it costs $6K/year to run a bank. That's not even remotely close. That would pay maybe a month of the desk clerk's salary + overhead.

The U.S. dollar isn't backed by gold. The total value of the gold at Fort Knox, about $100 billion, is negligible [1] and does not appear on the Federal Reserve's balance sheet [2]. It is mostly an anachronism from the eras of the gold standard.

The global financial system is interconnected. Fast transactions can happen because counter party risk is removed by a government backstop. In effect you can't have Visa without a "risk free" store of value. Vaults such as Fort Knox are a part of that system.

In the case of bitcoin they aren't inherently necessary to the function of the system, although with the risk of hacks you can make the case for them.

That's not very relevant. It's a constant factor, and the actual problem is that conventional financial systems is something of O(n log n) with respect to energy usage, and desperately tries to minimize it (as not minimizing it means bleeding money), while cryptocurrencies are incentivizing everyone to maximize their energy usage.
Re:Bitcoin Gold Hit by Double Spend Attack, Exchanges Lose M... by GW150914 on Wednesday May 23, 2018 @06:08PM (#17138813)
If locking it or running the firewall required energy waste on the order of bitcoin they would. Fortunately both have been designed with minimizing energy use in mind, rather than wastefully maximizing it.

How much energy is spent securing conventional financial systems? You have to include everything: banks, minting, enforcement, physical security, even military and intelligence action.
Re:Bitcoin Gold Hit by Double Spend Attack, Exchanges Lose M... by gtirloni on Wednesday May 23, 2018 @06:26PM (#17138964)
If/when cryptocurrencies reach the same size as conventional financial systems, they will require all of the same.

Bitcoin is relevant for the US economy and a rogue state tries to have 51% of hashing power? Military and intelligence to the rescue.

Someone is very rich in Bitcoins? Bunker services for offline storage, physical/computer security, etc.

Too many scams with altcoins? Legal enforcement, more bureaucracy, education, etc.

One could say that, somehow, the cryptocurrencies won't require as much of any of that, but I don't see this point being made as often (and not with any realistic estimations).

Re:Bitcoin Gold Hit by Double Spend Attack, Exchanges Lose M... by api on Thursday May 24, 2018 @08:14AM (#17143188)
The 51% scenario: just install more hash power. That would be cheaper and would not risk anyone's life.

Protecting cryptocurrency: there are cryptographic ways to achieve very high security that are free or very inexpensive. Physical encryption keys cost under $100. Combine those with multiple signatures and offline storage in a safe deposit box and you have several physical and cryptographic layers of security for pretty cheap. Services that do those things do not need to be very expensive.

Too many scams? Point taken. We will still need police.

BTW there's a reason I said cryptocurrency and not Bitcoin. Bitcoin is one of the slower cryptocurrencies. Energy spent securing the chain is per block, and its block size limit and other aspects of its design artificially boost its energy per TX. That and in the long term I expect people to find less energy intensive ways to secure block chains.

Re:Bitcoin Gold Hit by Double Spend Attack, Exchanges Lose M... by TeMPOraL on Thursday May 24, 2018 @12:07AM (#17141013)
For conventional financial systems, energy spending is upkeep. Something that needs to be done (due to thermodynamics), but is best minimized, because it costs money. So banks, minting, enforcement, branches, ATMs, etc. - they all try to minimize their upkeep, per the regular ways markets optimize this. All of this also arguably represents the lower bound of what it costs to run a financial system.

Cryptocurrencies, on the other hand, have energy use as a feature, not cost. Unlike conventional financial systems, cryptocurrencies try not to minimize energy expenditure, but maximize it, as a core function ensuring their integrity.

(Also, military and intelligence action count to stability of both conventional and cryptocurrency-based systems. After all, you can't run a crypto economy without stable and secure nation states with rule of law that allow for development and availability of advanced microelectronics (for mining), electricity and the Internet. Crypto is much more dependent on that than conventional systems.)

--

A tangentially related analogy that comes to mind: cryptocurrencies are like trying to build a city on a big hovering platform, kept aloft by great fans or jets. In order to keep the whole thing airborne, you'd find yourself constantly burning fuel just to counter gravity. Now we find this idea stupid because we can just build city on the ground and not waste any fuel at all - the surface of the Earth counters gravity for free. This is cryptocurrencies' relationship with trust. Trust works 99% of the time for free. Cryptocurrencies try to replace it with burning energy.

Re:Bitcoin Gold Hit by Double Spend Attack, Exchanges Lose M... by api on Thursday May 24, 2018 @08:04AM (#17143136)
I think the other reply about TX counts vs. people-hours of power convinced me that indeed cryptocurrency is much less efficient than conventional currency even if you put large error bars on that analysis. I do think it's a solvable problem.

Your reply about trust though...

Trust is massively less expensive until it's not. The trouble with trust is that when it breaks "fixing" it is immensely painful, often requiring major political upheaval or worse. In extreme cases people die when trust has to be "fixed."

I do still wonder... what happens when you amortize the cost of trust across say two hundred years time? Reminds me of the cost analysis of nuclear power. Nuclear power is cheap until Fukushima happens, and one Fukushima amortized over even 50-100 years renders nuclear power more expensive than any other energy source.

I do not think it's a coincidence that the cryptocurrency explosion happened right after the 2008 financial crisis. The level of corruption revealed by the crisis and by the nature of the state and financial sector response to the crisis (selective bailouts, bailouts only to the rich, bailouts that preserved the wealth of those responsible, etc.) showed that our trust in the financial sector and possibly in larger institutions is dangerous. People started looking for alternatives. I have doubts about whether cryptocurrency would have caught on to the level it has prior to 2008.

What cryptocurrency needs to be successful is some alternative to proof of work mining. I'm not convinced proof of stake is it since it has a lot of other problems.

What conventional economic systems need to be successful is a housecleaning and a restoration of public trust.

I've once worked out the CO2 output of Ethereum, which I think can be nicely worked over. Ethereum uses 191'000 people-equivalent CO2/year (1 PECO2 = 9 tons of CO2) or roughly 4 TWh per year (I'm using numbers from multiple sources and past comments from me, I apologize if it's not lining up perfectly)

The average state employes about 300'000 people (324'000) to be exact (about 16 million in total, which includes teachers and similar).

So already the Ethereum network uses half of an entire average US state to just secure it's network. The US state in question does a lot more and it includes education and similar.

Bitcoin uses 68 TWh anually, about 17 times as much or about 8.5 average US states. To secure 200'000 TX per day. In contrast the US employees handle the entire state affairs, including taxes, education, etc. for 54 million people every day.

I really feel like I shouldn't have to explicitly point out why this reasoning is so flawed, but to start with, bitcoin does not IN ANY WAY obviate the need for banks, law enforcement, physical security, or "military and intelligence".

Opportunity cost. All that 100% renewable energy could be used for something that actually adds value to society but isn't because it is being pissed away on the Rube Goldberg invention known as Satoshi's BlockChain.

> Also they pay for all the energy they spend so what exactly is the problem?

Give me a fucking break. These miners raise the price of electricity for everybody else and produce absolutely nothing of value to society at large.

Same thing these miners have done with graphics cards -- they've made graphics cards more expensive than most people can afford... you know, people who want to use those video cards for playing games instead of sucking down large quantities of non-renewable energy in a vain attempt to Get Rich Quick.

Bitcoin and all the others in the crypto "space" add absolutely zero value to society.

How much energy do you and everyone else waste doing things that don't add value to my life or society?

> How much energy do you and everyone else waste doing things that don't add value to my life or society?

Bitcoin is estimated to consume more than 0.5% of all the worlds energy. Many nations use less power than bitcoin consumes. Bitcoin can process a mere 4 transactions per second. Please go on and explain to me why this is even a remotely acceptable thing.

All you bitcoin shysters can keep telling yourself that to sleep at night, but you are lying to yourself and you know it.

Bitcoin consumes massive amounts of energy for a pathetically small amount of transactions per second. ON a per transaction basis, Bitcoin uses several orders of magnitude more energy than anything used by modern day financial systems.

Like, embarrassingly, shamefully large amounts of electricity. Y'all should bow your heads in shame for the harm you are doing to the world.

Your biggest mistake is comparing energy use. You need to compare the total overhead of bitcoin to the total overhead of the competitive financial system. The second mistake is comparing a per-transaction basis; this is of interest when we are comparing suitability for particular applications, but if you want to talk more generally about whether bitcoin is efficient for payments you need to look at things on a value basis (use usd, eur, cny, or gold ounces).

Sort of. It does create an opportunity cost, in diverting electricity away from other, arguably more useful causes. The whole matter there is complicated by economies of scale and baseload demand etc though. It could also be seen in terms of finiteness of the source of energy.

The measure of usefulness is determined by how much money people are willing to allocate towards it. Given that the money is allocated there, it indicates that for those actors, they see some utility regardless of what other people think. Hence, the only way to modify the unwanted behaviour is to correctly account for those producing the externalities, such that this market signal reverberates all the way through the economic chain.
Re:Bitcoin Gold Hit by Double Spend Attack, Exchanges Lose M... by Arbalest on Thursday May 24, 2018 @12:30AM (#17141110)
I agree with all of that except the definition of usefulness. As you eluded to with your use of regardless, rationality is not assured. It is expected (or more likely, hope) usefulness, aka speculation. Even funding the status quo is still speculation, because something could suddenly become not useful in the future. I suppose only time will tell what was actually useful, and I'm betting bitcoin is not among them. Maybe if proof of stake comes along, I'll consider that as more potentially useful.

Obviously capital allocation of individuals is not a perfect measure of utility, but it is the best/ fairest metric we have. Conveniently it provides a clear mechanism to sort out this mess. Price carbon pollution at the source and see the rest of the actors seeking profit fall in line. Miners will chose green energy, green energy will get more demand, their economies of scale will increase, pollution will decrease. Bitcoin energy use is no longer a problem and can provide whatever utility it is valued at without externalities.

If you had a mechanism to price externalities, and it wasn't government, then sure ok. But while we have no effective externality accounting and enforcement, this notion of wastage still exists fairly. If we could price in externalities with a government, then perhaps they would be more worthy of trust for currency too?

In terms of my original statement, I was effectively stating that the problem of decentralising currency doesn't really give back power to the people, because of the nature of wealth accumulation and propagation. Sure, it reduces the capacity for regulatory capture, but people with capital in whatever form still exercise a capacity to better maintain their capital base.

With regards to waste again, it becomes a moral issue. If we know that our externalities will cause problems, then by letting people continue to capitalise on them, we knowingly undermine the wider system we operate in. We have ethics committees for science and medical experiments, but when it comes to finance, experimentation occurs unimpeded. This leads to socio-economic outcomes which, while not fully understood, are also not complete unknowns.

It does not follow that if we can trust a Government to price carbon emissions then we should be able to trust them to not print money. We are basically guaranteed that they will, despite being able to effective disincentive things like smoking with an excise tax.

It is trivial for Governments to implement a carbon tax which would improve environmental conditions for all energy intensive production.

With regards to giving power to people, this is not done through wealth redistribution (although you get a little bit of that). The mechanism is tgrough the constraint that the currency can not be debased. A rising tide lifts all boats, especially when there are not holes in them.

Built in deflation you say? That once again, favours the incumbents. Those starting out will be at a disadvantage even more than they are now, for not having held any tokens of value. It also means that anyone who does attempt to do anything which requires money up front, whether that be starting a business, or starting a family, are at an even greater disadvantage. A rising tide lifts all boats, unless the boats haven't been built yet. Then it just becomes very difficult as more and more of the land is covered by the ever increasing tide.

You seem to be ignoring the status quo. I only need to prove it better than the current system, you need to prove that the current system is better. Those families and businesses that start from nothing still need money. Just that currently the money they do get is going to be worth less in the future.

Right, which means it is worth being spent. If spending is not worth it, then spending by and large dries up, resulting in a reduction of income to others, reducing the multiplier effect, and reducing the amount of actual trade that occurs. People continue to save as income opportunities dry up, and those with no income get royally screwed. With no risk taking occurring, things go back to bare essentials, which we are already very efficient at. Maintenance places are the only places which will maintain any expertise.

To be fair, I think there is already a risk of this, in any situation where capital becomes severely unequal. However, by making the monetary token itself an item of (appreciating) value, rather than only as means by which trade is mediated independently and in arbitrary small parts between multiple parties, is a sure way to speed that process up.

THIs is a wonderful story that doesn’t make any sense. You are suggesting that there are two sets of people, those with BTC that is increasing in value and those without. Those with are spending nothing and getting fabulously wealthy not spending their appreciating asset. Meanwhile, on the outside the no-coiners suffer from the lack of trade and become destitute and the economy drives to a halt.

This makes no sense for several reasons. The no-coiners could just buy a tiny fraction of a BTC with whatever fiat they have and become fabulously wealthy. When they do this they would be setting the market price even higher for all the rich Bitcoiners. All the of these fabulously wealthy holders think against deploying any capital to either enrich their life or increase their rate of return over asset appreciation.

It is absurd to think that as an entire population becomes wealthier that was risk taking occurs, when it it people that are mired in debt that often take less risk.

Before you respond remember these facts, the market price is set by buyers and sellers (trading). Bitcoin is infinitely divisible despite a capped supply. Gresham’s Law dictates that people will spend bad money first. Your no-coiner set has at least the ability to provide a service to begin wealth accumulation.

Should Read “less” risk taking.

By that flawed reasoning, BitConnect must have been extremely useful...

It's wasting if it's using more than the alternatives and it is using more than the alternatives.

"It's not waste if it serves a purpose. "

It's an open question as if it actually does serve a purpose, though.
