>What I don't get, is how do these prices actually change? For btc or a stock.

Easy, so take a look at this which was linked upthread: https://www.gdax.com/trade/BTC-USD

So the weird moving green and orange bars in the middle of the screen are the order book. Green is the 'buy' side of the book and orange is 'sell.' Buy and sell orders get matched, the sale goes through and both the buy and sell order disappear from the order book. If there's more demand to buy then the green bar starts eating into the orange section and pushes the price up. Vice versa in a crash, and it works the same way for stocks.

And you can see that the orange and green sections are cumulative. So if the price right now is $12000 I can scroll over $12,250 and it'll say something like 280 BTC, that number is how many bitcoins I have to buy to eat the order book up to $12,250 (which makes that the new price).
I agree. I'm learning Rust by rewriting someone else's small Python app in it. Rust requires you to define your variable types, especially for container types like vectors. I'm a decent Python programmer, and the app code is straightforward, but I realized I don't know what data the app operates on at each stage! I was forced to randomly insert print() around.

While cryptocurrencies price is clearly decoupled from any real work value. However, I'm really can't imagine what a realistic endgame will look like. Even if the bubble pops completely and Bitcoin goes to below $100, I am somewhat certain that the game will restart. There are enough believers to keep this going as a Ponzi scheme machine till the technology has matured enough and it's actually useful. If not that I expect it to longer around as some shady, mostly illegal gambling thing.
There's essentially nothing driving the price increase in 2017. Payment processing, remittance, asset-backing, digital identities, micropayments, bitcoin ATMs, VC-backed bitcoin startups, none of these things took off at all in 2017, in fact if anything the exciting years regarding these usecases/infrastructure ventures were 2013-2015.

I bet if you ask 100 people why they bought and if they use bitcoin for anything in particular, 99 will say no. That's why none of this is a real surprise.

On the other hand, apart from appreciation of gold as jewellery (partially because it's expensive) and some industrial use (fraction of the gold industry), in large part gold too exhibits price growth sustained by nothing but a simple cultural notion that it's scarce and valuable. Countries, banks, pension funds etc aren't putting hundreds of billions of dollars worth into stacks of gold bars locked in vaults because of their industrial or jewellery usage, after all. Bitcoin, as little the growth of real-life usecases has been in 2017, may have established itself as an alternative store of value. I don't agree with that myself (just as like I think it's utterly useless to invest in gold as a store of value), but who cares about me.

So it remains to be seen what'll happen the next ten years, maybe it'll still remain as a store of value. I'm no longer buying though. The 'using bitcoin' vs 'bitcoin as store of value' became completely lopsided in favour of the latter, which was the point I cashed out.
> When a very large scale economic or state collapse happens, the most important thing to have are a community of people around you who believe in each other.

But isn't that one of the hopes of cryptocurrency -- that it can survive a state collapse, because the relatively normal currency manipulation leading up to said collapse would be less (or not at all) viable? I feel like that was the spirit of OP's tongue in cheek remark and it's going over everyone's heads.

Also (this is pedantic) but many metals _do_ have intrinsic value (ex copper wiring or gold plated connections). It's slightly meaningful because (among other things, like its relative scarcity) has helped those metals be used as relatively stable currency in the past.
Usually, what people call "crash" are just corrections happening very fast. I think this one qualifies.

> Look at Quartz (Apple), ChromeOS (Google), and Android (Google).

Really good point. In my "last mile" comment I failed to address these success stories, but the two points are pretty complementary. MacOS abandoned Linux entirely. Android abandoned most of it - kept a lot of the system bits but threw away practically all of the bits a user (or even a typical developer) would see. ChromeOS is the closest to a real Linux desktop, and even it's changed quite a bit. I have a second-gen Chromebook Pixel laptop and I love the fact that I can use it both as a turnkey web-browsing appliance and as a real Linux development machine simultaneously (via crouton). But that only happened because Google invested millions in crossing that "last mile" for their own users. Many millions if you include all the money they've poured into Chrome and Google Docs and other things without which Chromebooks wouldn't be usable for most people.

I guess I should amend my point to say that native app based desktop Linux will always succumb to the last-mile problem. The very freedom that lets anyone develop whatever they want also means there will be regression to the mean when it comes to quality - and the mean just isn't good enough. Someone has to pay to raise that standard, and anyone who's paying won't pay for random half-finished crap. An integrated, polished system is the only kind of desktop the market will support.
I mean, I suppose anyone can create a currency out of thin air. In fact, I'd wager there's hundreds of currencies, as nearly every sovereign state has one. It's not meant to be a store of value, which is why this bubble will burst, but that doesn't mean it's doomed. It has the characteristics of a currency: 1. scarce. 2. useful.
PSSC Labs Launches PowerWulf HPC Clusters with Pre-Configured Data Center Blocks
Bitcoin Cash...
Things you can walk to a shop to and buy things with.
Things employers will pay you for.
Things that are backed by a government and guaranteed by a national bank.
Things that are protected by laws and monitored to prevent large value shifts.
Things that can be transferred in many transactions (like, more than four per second)
Things that don't need the energy production / consumption of a small country just to function.

Cryptocurrencies can have all that, but they need to have a high transaction volume (tens of thousands / second), regulation, protected / monitored exchange value, etc. Which defeats the original purpose of an "open source", unregulated currency.

But you get what you ask for.

It’s a cool idea, and I’m still optimistic, but I can’t think of a city where this idea works well. Riding a mobike is rough when it’s hot, or when it’s cold. It’s imposible in a city that’s not flat. And in cities where biking is nice, people already have bikes.

One of the infuriating things about Bitcoin is that there's no reason 19K couldn't be the new normal. You don't have to trade in whole Bitcoins, so high prices just mean people trade in smaller fractions and low prices just mean people trade in higher numbers, unlike a stock where you might want to do a split to make it easier for people to invest.

Its not a commodity it's a currency. Why does it need to be "rare"? The US dollar is also not backed by anything "rare" and hasn't been since Nixon abandoned the gold standard in 1973.

You realize this is the exact reason it was created right? That's the whole point. It's not coincidence that bitcoin was released on the heels of the 2008 financial crisis.

> bitcoin's fixed limit

That's what makes it unsuitable for being a currency.

> a uniquely closed & conserved system

Nope. Bitcoin may or may not be (lost wallets, as you point out, is one way in which it is not). But the ‘system’ is the economy, because money is moving in and out of bitcoin because it can be exchanged for other assets (goods, services, or other currencies when doing conversions).

So no. I'm not trying to be condescending, I'm just trying to nip this apparently valid but flawed analogy in the bud. The only commonality is the word ‘turbulence’ which is being used as a label for two entirely different phenomena that have some similitude and points of contact but are largely distinct and unrelatable.

sorry for this but you can eat gold.

Also, why does our currency need intrinsic value? It represents a debt owed and can be exchanged for things with intrinsic value. The reason dollars, yen, pounds, euros, silver, metal and gold have value is both a social and a legal contract. Cryptocurrencies may have some social contracts that give them value but they lack the legal contract. That's why I think they are doomed unless they open themselves to regulation.
But there's minimal non-trivial shared core logic, because the apps live in a different user space and do different things with different end goals.

You can port a Mac DAW to iOS - e.g. Cubase to Cubasis - but it's no longer the same product. Most of the features that make the desktop version so useful in a professional context are lost in translation, because iOS doesn't have the resources to support them.

Any currency that a:

is fundamentally valuable.

> American dollars have value because the US Government taxes things, like land, and if you do not pay those taxes they will send you mean letters (trust me) before resorting to other means (trust Al Capone). You pay these taxes in US dollars. You just having dollars does not make them valuable. And dollars are not valuable because they are backed by gold or silver or sea shells. What makes dollars valuable is that the government wants them back.

https://hackernoon.com/the-guns-of-bitcoin-1f779309a718

Ways to destroy the US dollar value: Destroy the US tax collecting power, or have the US ask for taxes in a different currency. If the US started collecting taxes in Euros, the value of the US dollar would disappear instantly.

The US is a strong entity and has no incentive to ruin the value of the dollar. It will not start collecting taxes in Euros. Or Bitcoin. Why would it give all that power away? More likely is that Bitcoin gets made illegal or very difficult to use. At the end of the day, if you have US-protected assets, you will have to pay US dollars to the US gov and this will continue to give USD value.

Bitcoin has no such strong-entity backing, so it has no fundamental value. Bitcoin people are obsessed with the idea that mere possession is important. It's not. Ask people with loads of marks or Zimbabwe dollars.
