> these articles always pretend a 20% selloff is the beginning of the end

There are individuals in this thread claiming "there will always be buyers" and that the probability of Bitcoin becoming worthless is zero.

The point of the article isn't that Bitcoin is doomed. It's that there is a substantial non-zero probability it ends up worthless. That such an elementary claim about a volatile asset is controversial almost says more than the article.

Ok can you talk more about your failure case then? What are the conditions like what exactly is the end result. There are 0 exchanges?
Re:It can all go to zero by tbabb on Tuesday January 16, 2018 @04:03PM (#16162558)
It absolutely boggles my mind that so many people in this thread cannot conceive of a run on crypto. I assume they probably don't even know what a "run" is.

And it boggles my mind that their only conception of failure is some kind of catastrophe or monumental event, like nuclear war, or quantum computing breaking cryptography. LITERALLY ALL THAT NEEDS TO HAPPEN IS THAT PEOPLE SUDDENLY WANT IT LESS. Excuse my caps.

If people doubt the future of crypto, then the price goes down. If the price goes down, crypto looks less attractive, so the price goes down more. This can spiral arbitrarily close to zero. No nuclear war or quantum computers needed.

What is being traded is like MMORPG game money or game items. They're only valuable as long as people want them. Crypto makes them unfakeable, but that doesn't mean people will want them.

My jaw is on the floor that this is beyond so many peoples' imagination.

Re:It can all go to zero by MichaelGG on Tuesday January 16, 2018 @04:07PM (#16162603)
Not to zero. I'd personally pay $1, probably more, for even 10% of all Bitcoins, just for the novelty. If there were no miners, maybe not much more than that, and I'd want the current private keys.

I'm guessing there's at least someone that'd pay a few million for all of Bitcoin, so maybe a $0.10-1.0 floor, easily? Would be illiquid and hard for small holders to sell though.

Also, quantum computers do not break Bitcoin entirely as in previously unused addresses are safe. You'd need a way to quickly generate keys matching a certain hash. Otherwise you need a ton of hashing power, too, to rewrite the part of the chain created in the time a spend-of-interest was created and you generated matching keys with your attacking machine. Seems like something that can be upgraded assuming a QC-resistant crypto scheme exists.

Re:It can all go to zero by ScottBurson on Tuesday January 16, 2018 @06:25PM (#16163875)
Sure, it won't go to literally zero (unlike stocks; companies can go bankrupt). But the difference between falling three orders of magnitude vs. six, say, is not a very big difference to anyone who bought in at current prices.
Re:It can all go to zero by akvadrako on Wednesday January 17, 2018 @07:53AM (#16167479)
But if it did go to $1, mining would become unprofitable until the next adjustment. So the only way forward is the network to fork. Then you wouldn't own "the Bitcoins", just "a Bitcoins".

It's funny, in this thread you dont really see much crypto optimism despite this meme being around for some time now.

> What is being traded is like MMORPG game money or game items.

There's definitely that aspect to crypto but its naive to think it's a dominant one. It might be like 10% maybe even less.

Is it really that unbelievable that bitcoin breaks certain economic rules and that some economic theory might have to be rethought? Is that what you are implying? That economics is like "science"?

Here's how this comment sounds:

"I don't understand what a run is, but somehow I'm pretty sure it's bullshit. I don't understand how economics works, but I'm pretty sure all the rules have been rewritten in some unspecified way that makes bitcoin invulnerable, and I'm in a better position to know this than people who actually have the understanding that I'm rejecting. My ignorance, which I have no burden to dispel, is better than your knowledge."

If that's not your viewpoint, then I'd love to hear what exactly you were getting at.

I understand what a run is, and like, is this high school economics or something? I just dont think that it entirely matches a run. You could say that same thing about stock. I'm not saying all economics, but some currently held believes might be generalized.

Also what exactly do you think is the required knowledge for this? Just economics? If so, you are off.

Yes, yes it is. It's incredibly remarkable that bitcoin could rewrite our economic theories so completely. It offers nothing novel in any way economically.

Ok, can you explain bitcoin in economic terms?

Re:It can all go to zero by Jtsummers on Tuesday January 16, 2018 @05:27PM (#16163323)
Sure. It's an overvalued, speculative commodity in a bubble. Ostensibly a currency, but without any of the useful features of a currency (effectively unusable for common transactions due to high fees, slow transaction confirmation rates, and highly unstable value). As a currency, assuming that its value stabilized, it suffers from being deflationary which will impede its ability to survive as either a global currency or a multi-generational currency.

Its current status is essentially a speculative commodity. But in that regard it has no utility. Most commodities are, well, something tangible or valued based on something else in the world. Bitcoin as a commodity has nothing backing it up other than its distributed ledger and the massive amount of computational power behind that. But the distributed ledger will see a drop in miners as the value of BTC drops, or an increase in fees to make it even less tenable as a currency than it already is. If BTC were a useful currency, then BTC the commodity would at least have that as a backing. In theory the commodity price and currency price would move towards each other (with one leading or lagging behind the other). But BTC the commodity has made BTC the currency essentially impossible to use due to the present overvaluation.

Regarding deflation and its inability to survive more than one or two generations, assuming some stability, if it maintains a modest 2% deflation rate the real value of a nominal amount of BTC would double every 32 years. So someone receiving 1 BTC as salary today would receive 0.5 BTC for the same work in approximately 32 years. Halved again 32 years later, the 3rd or 4th generation would receive 1/4 the salary of the first generation (in nominal terms) and have a fraction of the buying power.

I suppose a novel aspect of this is that it virtually eliminates the need for pensions as the mere presence of money in your wallet means you'll have more buying power in the future than now. Unfortunately this only makes financial inequality even worse than the situation we have today. Lending would be eliminated, or the terms would be so dreadful only the most desperate would seek it. Savings would go up, but in the "under the mattress" sense rather than the "in the bank" sense, where the money can at least continue to have some utility by being lended out to others by the bank. A massive economic drag.

None of this is novel stuff, from an economics standpoint.

Re:It can all go to zero by tbabb on Tuesday January 16, 2018 @05:40PM (#16163442)
I would also add to:

> As a currency, assuming that its value stabilized

by pointing out that without a central bank, a stable value is literally impossible, because its price becomes entirely demand-driven.

That alone is enough to bring its hope of being a meaningful currency in stable society to zilch.

Re:It can all go to zero by Giorgi on Tuesday January 16, 2018 @06:11PM (#16163731)
>effectively unusable for common transactions due to high fees, slow transaction confirmation rates, and highly unstable value

Correct, but you somehow missed how demand for bitcoin was actually created - it is somewhat untraceable currency therefore used in "black market" transactions.

As those markets develop they will demand such currency in one way or another and that's novelty from an economics standpoint.

Re:It can all go to zero by Jtsummers on Tuesday January 16, 2018 @06:18PM (#16163810)
This is true, I didn't mention that. That is a useful detail but ended up being a short-lived portion of bitcoins life overall as its pseudonymity was fairly quickly foiled through network analysis. Other crypto currencies will fare better in that regard and could become one of or the crypto for black market trade.

But that was also something that held back bitcoins valuation. In 2011/2012 anyone who heard of it either understood its technical features, or thought it was "that thing for buying drugs online". Once it stopped being the latter (at least in common perception) the speculation really began in earnest as the exchanges were able to gain access to banks and other financial institutions.

A blackmarket crypto that retains that reputation, whether used for legitimate business or not, will likely find its global valuation impaired by that reputation like bitcoin and it will be difficult for average folks with no interest in the blackmarket economy from "investing" in it.

It certainly will be interesting.

Re:It can all go to zero by adamnemecek on Tuesday January 16, 2018 @06:36PM (#16163956)
You are missing a lot of things. Like it's not just economic. Also your argument talks about bitcoin but not the other cryptocurrencies that might not have the some of the features you describe.

> Sure. It's an overvalued, speculative commodity in a bubble.

Overvalued compared with what? Speculative is an opinion.

> Ostensibly a currency, but without any of the useful features of a currency

With a fundamentally different set of features. Like being able to exchange with literally anyone in the world is unprecedented. Again, Bitcoin has opened many new markets, e.g. I can trade with North Korea with it. It also lets the underbanked people fight back against their government. E.g. I can pay a worker in Zimbabwe much easier than before. This could drive up the adoption rate to unprecedented levels.

> Most commodities are, well, something tangible or valued based on something else in the world. Bitcoin as a commodity has nothing backing it up other than its distributed ledger and the massive amount of computational power behind that.

The backing part of commodities is greatly exaggerated. Who cares? Is that why you are using dollars? It's a protocol that lets me plugin to the world economy. That's unprecedented.

You talk about BTC but like BTC is not the end all. There's like 7000 crypto, some of which are shit but some have like ...serious research behind them.

As a trading instrument it's so much better than stock. With stock you have to wait three days. I guess the closest is Forex but forex is just so boring.

You asked me to explain bitcoin, I did.

> Overvalued compared with what? Speculative is an opinion.

Overvalued compared to its utility as a currency, which is what it ostensibly is. As a currency it presently has no value because the overall BTC valuation is so high and so unstable, paired with the transaction fees and delays.

Speculation is not an opinion here. Look at how many people are "investing" in it with no comprehension of what it is and what it does.

> Like being able to exchange with literally anyone in the world is unprecedented.

For all practical purposes I can exchange Euros and US dollars with anyone in the world, modulo a few countries that have stricter and enforced policies. I was in Uruguay last July and was able to use USD at shops because the other option was credit card (exchange rate set at the end of the day) or ARS (cash on hand) and the exchange rate was better with the posted USD->UYU was better than either of those (as long as I used at least a $20 bill). No questions asked, they just took it and I got the goods I wanted.

> I can trade with North Korea with it.

I will agree that it does eliminate or reduce the effectiveness of economic sanctions in some situations, like this one. However, if you're a US citizen conducting business with NK is still illegal or tightly controlled, and bitcoin is only pseudonymous. And with regard to opening up financial interactions with people across borders, that is a potentially very useful thing. But at the moment it is not a feasible thing with bitcoin.

> The backing part of commodities is greatly exaggerated. Who cares?

The people seeking profit off of them. If a commodity doesn't have something behind it, its value will fall. When it will fall can be a while in the future depending on the general hype and/or confidence. Bitcoin is all hope, no real confidence, and no real utility (at present).

> You talk about BTC but like BTC is not the end all.

You asked about bitcoin, I answered about bitcoin.

> As a trading instrument it's so much better than stock. With stock you have to wait three days. I guess the closest is Forex but forex is just so boring.

Three days? Three days for what? And better in what way? In the "I enjoy rollercoasters" sense? Then sure, it's better that way. At least with stocks (or the ones I invest in) I can examine the fundamentals of a company, the global and national economies they play in, and have some idea of whether they're overvalued or undervalued at any given time with ease. Most Forex is the same.

Bitcoin, the thing you asked about, is not useful as a currency. So it's only useful, right now, as a commodity and in trading on various exchanges as a commodity. It is pure speculation until the value on those exchanges and the value of things I can purchase with are closer together than they are today.

It's not just a currency. It's part stock, part currency, part forex, part world of warcraft money, part political movement, part programming platform, part distributed database etc etc. Like the number of categories it fits into is a lot.

Ok talk about ethereum. Does ethereum have intrinsic value?

Is everyone investing into bitcoin speculating? Is possible that some people know what it is and still want to invest?

That was an extreme example.

Let me tell you a story.

My parents, before I was born, worked as teachers in Africa. They were sent via an agreement of our (communist) state with the Belgian government and were paid "expat" money. Only problem is, they knew that when they came back the government would take all their money (coerce them to exchange it at shit exchange rate, for a currency that was basically worthless). So they invested - they bought stuff. What did they buy? Well, they figured that ivory can only increase in value. So they bought ivory carvings - african art. We're sitting on a bunch of it - except for the artistic/decorative value... the monetary value is zero. Nobody touches ivory. Unless I'm willing to deal with some very shady persons and risk jailtime - I can't turn it to cash.

You think it's unlikely that governments worldwide would ban any given crypto - including BTC? Just watch what happened recently in a few countries....

Re:It can all go to zero by adamnemecek on Tuesday January 16, 2018 @03:15PM (#16161972)
Let me preface this story by saying that your parents did a shit thing and I'm glad they were duly punished. Fuck ivory. But I'm getting distracted.

Bitcoin is unlike your situation as with ivory you have to have physical contact with the shady person. With BTC you don't. People online don't care as much about dealing with shady people. It's also kinda hard to tell who's a shady person online.

Bitcoin is so divisive you've managed to shit on his parents to win an argument.

An argument that you then concede, saying that it doesn't matter whether BTC is legal or not because you can always sell it online.

If it's illegal, doesn't it's value go way down? If you literally risk jailtime to sell it (or more accurate, to convert it to fiat eventually)

> If it's illegal, doesn't it's value go way down? If you literally risk jailtime to sell it (or more accurate, to convert it to fiat eventually)

So like all governments at once will outlaw doing anything with crypto? Like not regulate it, even if heavily, they'll just basically make owning crypto as illegal as owning idk, child porn (pardon for the repeat analogy). Like you aren't realizing the impossibility of making something like crypto illegal.

Re:It can all go to zero by virgilp on Tuesday January 16, 2018 @04:17PM (#16162692)
"Heavy regulation" is quite enough to take any particular coin to 0 value.

> Not really, I dislike the fact that he volunteers this information. Replace ivory with child pornography (ethically they aren't that different).

Well, they're quite different. Morally, legally, whatever, the society at large assigns larger value to a human than to an animal - any animal. Plus, they didn't do anything illegally - at the time they bought it, it was legal to buy it and sell it anywhere in the world.

You're now eating meat. It's quite conceivable that there might be a future where eating meat obtained through killing animals is considered as barbaric as you are now considering ivory trade. Different time, different people.

I only told you about ivory because it was __relevant__. It's a thing you can relate to - that people did in the past, without giving it much thought. Ponzi schemes are outlawed and considered imoral - do you consider _impossible_ a future where a marketing campaign convinces people that crypto is just a form of ponzi scheme, and participating in one is not just stupid and illegal, but also imoral?

The classic one. Nobody wants to pay more than a token amount for Bitcoin. Maybe central banks jacked up rates or we went into a recession or something newer and shinier came about.

Value crashes, miners find it more valuable to sell their equipment than keep mining or confirming transactions, the entire ecosystem compresses to where it was when it was more about tinkering. Maybe it remains somewhat relevant, as a curiosity. Our generation's Esperanto.

Re:It can all go to zero by adamnemecek on Tuesday January 16, 2018 @02:44PM (#16161581)
I'm not saying it's not possible, like that the possibility is zero, all I'm saying is that it's not that much more likely that the same happening with other things. And like Bitcoin is actually resistant to some of the factors that could make other things go to zero. All I'm saying, there's a little too much "BTC will be zero, I was it in a Hollywood movie" and not enough of "BTC will go to zero if the following scenarios happened. It will go to the moon if these happened". I wont see these since these don't go with the preconceived notions and one might actually have to understand "economics of online", international relations, cryptography, networking and like so much other shit. The people who I think are qualified to write about crypto is maybe Satoshi Nakamoto but even he didn't quite nail all of it.
Re:It can all go to zero by prostoalex on Thursday January 18, 2018 @03:24PM (#16181014)
It’s not about holding, it’s about backstop.

A company’s stock (or bond) is a right to get some compensation in case of dissolution, bankruptcy, or liquidation sale. A precious metal like gold still has a backstop value - it can be sold to electronics manufacturers to make those beautiful gold-plated audio cables. Diamonds have a backstop value of being used in boring and drilling. Vacated real estate can be converted to other uses.

All of those assets (when owned outright and not pledged) are unlikely to go to $0.

That's beside the point. The stock won't go to zero because it represents a share of ownership in a company that has billions of dollars more in assets than in liabilities. Real estate is just one of the many assets.

Someone announces they have had a large quantum computer for a while and have cracked every public key on the blockchain. That'd probably do it. Quantum Jubilee, y'all. The year of decryption, all private keys revealed, all captive coins set free. It's just a matter of engineering at this point. Give it roughly 10 years.

Not only cryptography coins,even traditional banking,e-commerce,and our modern society would go down. Quantum for all.
Re:It can all go to zero by bringtheaction on Tuesday January 16, 2018 @02:43PM (#16161577)
Exactly and in fact some crypto currencies claim to be working on making quantum computing resistant crypto currency. So if someone made a claim like envisioned by GP and could prove it, certain crypto currencies might do just the opposite of going to zero.
Re:It can all go to zero by Robotbeat on Tuesday January 16, 2018 @03:03PM (#16161805)
Yup. Quantum Jubilee is coming. But interestingly, even just the credible threat of Quantum Jubilee could have devastating effects on Bitcoin classic. Banks might be better prepared to switch over to quantum-resistant encryption since they're already centralized.
Re:It can all go to zero by ric2b on Wednesday January 17, 2018 @06:43AM (#16167133)
Banks are still stuck on 70's infrastructure and hiring 70 year old programmers with 500k+/year salaries to write COBOL because they're afraid to rebuild it.

I'm not sure I'd bet on them having a quicker response than an open-source project with millions of interested parties.

I think modern society going down is a bit of a stretch here. There are quantum-resistant cryptographic algorithms that would be safe even against quantum computers.
Re:It can all go to zero by Robotbeat on Tuesday January 16, 2018 @03:14PM (#16161948)
However, EVERYTHING has to switch over before it happens. Everyone has to change all their passwords and security questions and private keys.

Additionally, anything sent over the Internet via ANY of the standardized public key encryption algorithms can be skimmed and stored right now and decrypted once quantum computers are available. Social security numbers, bank account numbers, credit card numbers, security question answers, tax returns, trade secrets, personal details, Signal messages between elected officials and/or dissidents, informants, etc... All in clear text to anyone with forethought to start storing it right now.

Changing to a quantum resistant algorithm doesn't change the past; it doesn't change data that has already been archived.

That's why Quantum Jubilee is going to be such a big deal. Not only do you have the usual slowness in deploying new encryption standards (thus likely exposing industrial equipment, etc), but everything being sent right now is already at risk.

And we don't know when it'll happen. Could be 5 years from now, could be 15. Could have already happened in secret (unlikely, but still possible).

Re:It can all go to zero by monort on Tuesday January 16, 2018 @04:08PM (#16162612)
This is not possible because public keys you want to crack are in hashed form RIPE-160(SHA256(public_key)). Grover's search algorithm can help with it, but speedup is much less, than with Shor's algorithm and won't be of much help with sha256.
Re:It can all go to zero by Robotbeat on Tuesday January 16, 2018 @05:10PM (#16163200)
You are correct that the blockchain has hashed the public key and so isn't directly attackable, except that the public key must be revealed at some point. Therefore, it is still possible to recover the private key (and if you can do this faster than the transaction can enter the blockchain, you can potentially steal the bitcoin).

However, if you wanted to break the hashed private key, you don't need to solve 256 bits. Grover's algorithm is a search, thus difficulty scales with the final hash key length, not the intermediate hashes. Still, it's only a quadratic speed-up and 160 bits is still pretty tough. But that's fine, as you can still intercept the public keys before they're hashed on the blockchain.

Re:It can all go to zero by teraflop on Tuesday January 16, 2018 @02:11PM (#16161206)
It's a possibility. Maybe they'll still be here, maybe they'll be totally gone; maybe they'll exist, but only in certain niches, or in a form that's unrecognizably different than what they look like now.

By analogy: two decades ago, US consumers were buying almost a billion dollars' worth of photographic film a year [1]. Photography hasn't gone anywhere -- people are taking orders of magnitude more photos than they used to -- but if you had invested your entire net worth into Kodak in 2000, you'd be penniless now.

Ok so we disagree on whether Bitcoin has peaked or not. Do you feel like crypto has peaked? There's this half trilion just waiting to be multiplied. Like people just bought in, they wont be selling. In some sense, I wonder if the fact that beginner investors bought in means that it's more resistant to a price dump as they wont have stop losses. If they bought for 1000, they wont sell for 500 thereby keeping the price afloat. Not saying that's the case.
Re:It can all go to zero by Jtsummers on Tuesday January 16, 2018 @03:40PM (#16162288)
Someone buying for $1000 and not selling for $500 will not keep the price afloat. It just means they're stuck with something they refuse to sell and no one else wants to buy. Other people will sell at the lower price (to get out and write off their losses rather than incur more) and the price will drop anyways.

"Could be"? Dude, this is why people bought fucking Beanie Babies 20 years ago and held them. Hell, I have 10 in my apartment because my grandfather was buying and trading them in the late 90s. Thank god he traded enough for a profit, he was essentially break even at the end of that bubble. Some people bought them expecting the absurd valuation to continue. See also comic book and baseball card bubbles that started in the 1990s. People held them until they were valueless. Now there's a glut on the market and no one wants the damn things.

That's irrelevant. If every cryptocurrency around in 30 years has yet to be created then every current cryptocurrency would be dead.

Consider, what happens if the Internet dies? Well you could run a private coin on an old laptop, but that's not really meaningful.

Re:It can all go to zero by adamnemecek on Tuesday January 16, 2018 @03:35PM (#16162219)
It's not an overnight thing. Like the transfer from Bitcoin to the new thing would be very gradual, standard technology adoption rate curve. And like, it's not clear by how much would you really diminish Bitcoin. Like crpyto became a thing but I dont think it was at the stock market.

Re:It can all go to zero by oreo81 on Tuesday January 16, 2018 @03:44PM (#16162333)
All those of those are examples of numbers that have already been discovered, not preemptively banning numbers yet to be found.
Re:It can all go to zero by em3rgent0rdr on Tuesday January 16, 2018 @05:34PM (#16163396)
They still pre-emptively ban numbers, for instance if they represent something illegal: "Any image file or an executable program can be regarded as simply a very large binary number. In certain jurisdictions, there are images that are illegal to possess, due to obscenity or secrecy/classified status, so the corresponding numbers could be illegal."

Also, the concept of "numbers yet to be found" is philosophically questionable.

That particular way seems extremely unlikely, at least in the case of Bitcoin. It was specifically designed so that it should be impossible to dilute the currency like that. Nobody is supposed to be able to directly control the supply of BTC, and the rate at which new BTC is created is steadily decreasing toward zero.

So going to zero in that particular way would presume that there's a vulnerability in the protocol that makes it possible to manufacture effectively unlimited bitcoin outside the normal channels, and that nobody is able to figure out a way to defend against it.

Re:It can all go to zero by adamnemecek on Tuesday January 16, 2018 @03:17PM (#16161989)
Its good that you are bringing this up. Bitcoin is entirely resistant to this, which can be demonstrated by the fact that Bitcoin is supposed to be popular in Zimbabwe.
Re:It can all go to zero by martin1975 on Tuesday January 16, 2018 @03:25PM (#16162093)
1) Bitcoin becomes too expensive to mine or even sustain due to energy prices

2) Bitcoin's blockchain grows to petabytes or exabytes in size thus becoming horrendously slow to both replicate or even host

3) Bitcoin is surpassed by a better technology, such as Cardano or IOTA. This won't kill it but it will stunt/cap its growth indefinitely.

4) Bitcoin fails to integrate into the legacy world fully by remaining pseudonymous, reluctant or refusing to comply with AML/KYC regulations everywhere in the world, developed or not. It then maxes out in growth. Again, not a failure case, as whatever value was there will probably still remain, but it will be dwindled down significantly.

I'm sure there's more but I can't think of all of them...

Re:It can all go to zero by martin1975 on Tuesday January 16, 2018 @03:53PM (#16162435)
No legacy ever really goes away. However it slips into irrelevance unless it's built on sound foundations that can be evolved. Sad to say, no PoW currency has a sound foundation that can be expanded and evolved... like tcp/ip has been able to evolve over the last 40-50 years.

That it's such an elementary claim is the reason for the pushback. What's the point in saying something obvious?

Saying something obvious (e.g. circles are round) isn't the same as refuting something obvious (e.g. circles are squares).

Because people unfailingly pushback against it. The pushers should start their push acknowledging that it is possible if it’s really such an elementary claim to them.
