People are always quick to point out that this is just what it takes to build a trustless and decentralized currency, which is probably correct, but it's not clear whether such an extreme level of trustlessness is even necessary (if you are not a crypto-libertarian on principle). The benchmark for Bitcoin are normal financial transactions as they exist today (and work quite well, most of the time). So the question really is: Are you ready to have humanity spend the additional energy consumption of a country (or many countries if Bitcoin were to scale up) to run a system that offers only very limited throughput (relative to established systems) and hasn't even proven yet that it's even a viable alternative to fiat money from an economic perspective? Not to mention the scaling issues that come with such broadcast protocol. I don't really see the widespread use, at least as envisioned by Bitcoin proponents. If it's just the decentralized aspect and transparency that you want, you can relax your trust assumptions and implement something like a distributed ledger with known identities which doesn't need proof-of-work to prevent sybil attacks (identities which of course would have to be certified in some way, unfortunate). Oh well, it's still a very cool technology, but I hope for the planet's sake that cryptocurrencies stay in their niche of anonymous transactions for those who actually need it.

Agree. Bitcoin is a fun experiment / proof of concept. I'd add that I hope we will eventually tackle the energy problem, hopefully without throwing away the good parts of decentralization / distributed ledgers. It might be optimistic, but I think many early technological revolutions bring learning costs and risk environmental damage.

It's all fun and games until Shor's algorithm, anyway. If Bitcoin is broken-in-the-long-term in one way why not admit it's broken in another, and iterate to a better solution.

  Bitcoin can change it's own code whenever it wants, its not a static thing, it can become a better solution.

It's all about immutability and finite money supply. Huge achievements that are impossible with centralized government fiat. Here's an articulate presentation on these qualities of Bitcoin that many argue are it's primary function, viewing it as an ideal store of value[0]. Here also is a book by George Gilder on the flaws of fiat currency vs sound money[1], but which also covers a much broader spectrum of economic issues we've face in recent decades, and highlights qualities of Bitcoin (and to a lesser extent gold) that counteract these trends. They both support the argument that Bitcoin is not primarily useful as a high volume, high speed payment network (though 2nd layer solutions can serve this purpose, as well as a decrease in the rate of price appreciation long term), but rather as a store of value, mainly concerned with locking value away from central banks and governments, and in practice would as you highlight be most useful for higher value lower speed transactions. The economic argument of sound money is that it promotes low time preference [2] vs inflationary money incentivizing high time preference.

  > It's all about immutability and finite money supply. and why do we care about those? Finite money supply, I get. I'm not I agree but I get it. Why exactly do I need an immutable record that I paid some guy 10 bucks for a souvenir shirt at a concert? That I stopped and grabbed a coke at mcdonalds on the way home. That I went and bought some legal weed.

    It has nothing to do with recording exactly what each person bought. It’s about making sure that you can’t spend the SAME 10 bucks on a shirt AND some weed, and that you can’t pull the 10 bucks back out of the store owners’ accounts after you run off with the products.

You think we should be blocked from donating to wikileaks? You think venezuelans should be forced to use their local currency? You think Zimbabwe's people should go thru hyper inflation again? They are about to, and bitcoin is booming there as an alternative. Sorry, you seem to think you know better than other people what they should value and what they should do. Bitcoin is completely voluntary, you don't like it, don't participate. It's also not your energy getting spent. At the risk of sounding like a libertarian: Other people are not your property.

  Oh come on. We should be charitable in our discussions. The comment clearly mentions that there are some useful applications, which cover the censorship and collapsing government use-cases. The important thing to recognize is that the large majority of people don't have these use-cases. This means that BTC becomes a niche system rather than supplanting world banking. It isn't my energy being spent, but it is CO2 that harms our planet. Until we have zero-emissions energy I think it is reasonable to criticize systems as energy-inefficient.

    Why are we blaming the individuals who use the energy rather than the individuals who make the energy dirty in the first place. Place the blame where autonomy is.
    - ben_w 9y ago
      There is plenty of autonomy to blame when someone chooses to use an absurdly large amount of energy when a trivial amount would solve the same problem.

  As I recall, Zimbabwe banned other currencies last time. Why do you think Bitcoin wouldn’t get banned with all the other currencies if the situation repeated? And don’t bother suggesting a Bitcoin ban wouldn’t be enforceable unless you can say why the same excuse wouldn’t also apply to every other currency.

I think bitcoin will be used as a store of value rather than for daily transactions.

  The long term usefulness is the transactions. Without that, the interest can dry up quickly.

    which is why people call it a bubble.
