> It could be possible to regulate exchanges dealing with fiat, but I feel like the regulable surface area is thin.

It may be thin, but it covers most people. Most crypto buyers use fiat exchanges. If those were ruled out, the monetary value of tokens would go down, and with it the mining incentives would lower. It wouldn't be the end of crypto, but it would alleviate many issues (energy, hardware shortage, etc).

PS: I don't think crypto is the only reason for GPU shortage (others being more demand from stay-at-home people, and general semiconductor shortages), but I believe it plays a part.

So basically get rid of all the legitimate use cases and leave the nefarious ones? Not everyone lives in the developed world where they can just Venmo their friends for brunch. Some people live in counties with capital controls that means they see their wealth disappear year after year.

Gamers in western countries have to pay slightly higher prices for their high end gaming GPUs. Excuse me while I clutch my pearls!

The cavalier attitude people have about this tech is really disheartening to see.

[mikepurvis]

Can anyone claim with a straight face that the current state of the crypto ecosystem permits use cases like "splitting a bill with your friends after lunch" or "hiding your earnings from unjust taxation"?

It may aspire to be/do these things, and that's great, but that’s not the present reality.

[bko]

It's the base layer of payment system. There will be a layer on top of it for things like that. When you split a check on venmo, that money isn't really there until a few days. The venmo system is a few layers removed from the equivalent of Bitcoin..

What Bitcoin provides is sound money with a fixed predictable supply not at the whims of politicians and fed officials. There is no way to increase the supply of Bitcoin by 23% like we had with the us dollar over the last year

[jfk13]

I would expect "sound money" to have a fairly stable, predictable value in terms of real-world goods and services for which it can be exchanged. I haven't observed that to be the case for Bitcoin.

Being "at the whims of politicians and fed officials" seems in practice to provide much better stability than being at the whims of a horde of reddit "investors" (or a cabal of Chinese miners).

Not to mention almost everyone I know who "invests" in crypto does so "at the whims of politicians and fed officials." SEC rulings and the likes.

How many monkey butlers will there be?

A naturally deflationary currency is such a bad idea that every single country went away from them in a fairly short time period.

[vngzs]

If you want a (relatively) untraceable cryptocurrency, they exist [0]. Yes, most cryptocurrencies are _perfectly_ traceable - you can trace the source/destination of every transaction - contrary to the common narrative.

> slightly higher prices for their high end gaming GPUs

This is across the board, not just for high-end cards.

Newegg has a total of one graphics card released in the past 5 years in stock that it sells directly (https://www.newegg.com/p/1DW-001Z-00042), a RX 550 going for $200 (plus $8 shipping) -- the 2GB model launched at a MSRP of $79; I assume the 4GB model's MSRP would be somewhere between that and the $99 MSRP of the RX 560.

The rest of the items for sale are third parties which are often no-name brands/shippers from China (e.g. Yeston which seems to have lackluster reviews about short warranty and sloppy build quality, Corn which has many horror stories about shipping delays or just missing products), and all have similarly drastically hiked prices. Next cheapest card shipped from the US is a 560 at $279+15.

The 550 is by no means a high-end gaming GPU, nor was it when it came out.

[bko]

I think you're missing my point.

No one has a claim on any one product such that they can demand the destruction of something millions of people find value in and that has a market value of a trillion dollars so you can have your GPU return to a price in the past that they found reasonable

[vitus]

You're exaggerating why people dislike cryptocurrency by focusing on a singular reason.

I think the root cause is because it's conflated with bitcoin and the PoW system it's built on top of, which is generally considered to be unproductive. Take away PoW, and you remove the incentives for miners to suck up vast amounts of electricity, the supply of graphics cards, probably even infrastructure hijacks to some point.

(And yes, I understand that the graphic card shortage is more strongly tied to Ethereum's ASIC-resistant hash. But that's still a PoW system.)

[bko]

Bitcoin and PoW crypto is priced to the global lowest cost of energy. For instance, it would not be economical mine bitcoin in Los Angeles in the middle of the day in August. Most of the mining happens in remote areas in China where there is abundant cheap energy at off-peak times.

So it's not fair to look at pure energy used by the Bitcoin network as though its some fungible limited supply that we can just move away from Bitcoin production and move to Texas during the winter storm.

Regarding carbon emission, that's a political problem. If you want to create a tax on carbon, you can do that, although I'd prefer carbon capture tech. But in no way should some governing body try to allocate the validity of carbon emissions based on purpose. That would be no different than central planning where some central authority determines how many X should be produced, when and where. It's been tried and failed.

But look at the point of PoW and the purpose of crypto. Its sound money and has value, and an expense to maintain. Whats the alternative? Create a currency with a trusted central bank, and build an army to defend your organization when someone uses your currency to "fund terrorism"? I imagine there's CO2 emissions w/ maintaining an army as well

[rudderz]

HN has hated crypto for a decade now and it's only recently been about energy consumption. It was and will be about monetary policy and the role of government in issuing currency. Kaynes vs Hayek kind of thing. Which in a way is about authoritarian vs market forces. For some reason Hacker News really likes the idea of centralized authority and criminalizing things like math and free association by threat of violence and imprisonment.

> For some reason Hacker News really likes the idea of centralized authority and criminalizing things like math and free association by threat of violence and imprisonment.

The new kind of "geek" in the opposite of the traditional "geek" who was a libertarian / pro freedom.

My guess is that most geeks can't afford to bite the hand that feeds them (google/facebook/twitter...) so they decided to loudly proclaim their allegiance to modern values (environmentalism/social justice/wokeness in general)

[jfk13]

> Some people live in counties with capital controls that means they see their wealth disappear year after year.

So the purpose of cryptocurrency here is to enable people to evade the laws of the society in which they live? Not sure I can regard that as a "legitimate use case".

> slightly higher prices for their high end gaming GPUs

I do not care about that part, but massive amount of scams around BTC and similar is fueling my growing dislike.

As a moderator on small forum most of the work is blocking cryptocurrency scammers.

The saddest part is that apparently they steal enough money to keep their crime profitable.

[bigbob2]

Under PoW each of those GPUs consumes significant energy and that's the real issue. It seems like a fairly cavalier attitude to ignore that fact. Maybe PoW will be fine in 200 years when fossil fuels are finally phased out, but likely not in this century.

Then why are only GPUs unavailable?

We can still easily buy CPUs, memory, SSDs, etc.

[mschuster91]

Memory and SSD chips are made on older processes with coarser structures which means that they're more or less unaffected by the current limitations in manufacturing capacity that CPUs and GPUs suffer.

[bayindirh]

> Then why are only GPUs unavailable?

Because they're harder to build, and there is some serious HPC capacity is being built up right now around the world, which buys these chips buy thousands.

Same entities which hoard Tesla GPUs are not interested in unregistered RAM, consumer SSDs and CPUs. Unfortunately, a run of the mill Tesla is not much different from a GeForce. OTOH, RAM, CPU and SSD for these applications are built from different parts.
