Personally I think that this can be considered on the "bug" side of Bitcoin's finite number coins: if, over time, they are lost, then there's a smaller quantity† of currency that is useable to actually do stuff with.

This can make the 'rate of deflation' that occurs worse:

Which can limit economic growth. When money was based the amount of gold available, there were long periods of economic stagnation because of liquidity issues:

* https://en.wikipedia.org/wiki/Long_Depression

* https://en.wikipedia.org/wiki/Great_Bullion_Famine

The stagnation only ended when new sources of shiny rocks were found (California; New World).

I find it a dumb idea what whether or not people can get credit to start/expand businesses would be dependent of solving math problems. Yes, credit creation can be "too easy" and become a problem, but making it "too hard" (or physically/mathematically impossible) is even more dumb.

During the "long depression" GDP was still growing at 3-4% so it was hardly stagnation.

throw0101d•26m ago
> During the "long depression" GDP was still growing at 3-4% so it was hardly stagnation.

I don't know of many things that are viewed positively that have been given a label with "depression" in it.

> Figures from Milton Friedman and Anna Schwartz show net national product increased 3 percent per year from 1869 to 1879 and real national product grew at 6.8 percent per year during that time frame.[32] However, since between 1869 and 1879 the population of the United States increased by over 17.5 percent,[33] per capita NNP growth was lower. Following the end of the episode in 1879, the U.S. economy would remain unstable, experiencing recessions for 114 of the 253 months until January 1901.[34]

> The dramatic shift in prices mauled nominal wages – in the United States, nominal wages declined by one-quarter during the 1870s,[14] and as much as one-half in some places, such as Pennsylvania.[35] Although real wages had enjoyed robust growth in the aftermath of the American Civil War, increasing by nearly a quarter between 1865 and 1873, they stagnated until the 1880s, posting no real growth, before resuming their robust rate of expansion in the later 1880s.[36] The collapse of cotton prices devastated the already war-ravaged economy of the southern United States.[17]

> Thousands of American businesses failed, defaulting on more than a billion dollars of debt.[35] One in four laborers in New York were out of work in the winter of 1873–1874[35] and, nationally, a million became unemployed.[35]

In US in 19th century stocks of banks that went bankrupt were used as a sort of paper money to solve the problem of money availability.

So the finite amount of base money would just mean that derivative products would be used as practical money.

Bitcoin is the world's number one store of value for converting young, impressionable men's wages into thin air and moving those dollars to other people instead.

It's a compelling rival to multi-level marketing for women in that both prospects entice low-socioeconomic standing peoples into thinking they are building value instead of consuming it.

latchkey•2m ago
It’s a solid store of value. One can borrow against that held BTC, and as it appreciates over time, the loan-to-value ratio improves, without having to do anything. Also avoids capital gains taxes since you're not spending it.

And is deflation a good or bad thing for the livelihood and well-being of human beings?

How many people in the US has a mortgage or some kind of debt (student, medical)? Inflation makes the burden of debt easier, deflation makes it worse.

And the Top (0.)1% already has an easy enough time with parking/generating value. Deflation would only help them more (and make things hard for everyone under them).

logicchains•1h ago
Inflation punishes savers and rewards debtors, i.e. it disincentivises the more economically productive behaviour.
thunderfork•1h ago
Isn't saving (i.e. sitting on assets) less economically productive than spending? Inflation rewards productivity by making productive use of money the only way to avoid loss over time?
NeutralCrane•53m ago
Saving isn’t economically productive, on a societal level. Spending is. Investing is.

Deflation inherently disincentivizes doing anything with the currency other than sitting on it. Want to buy something? You’d be better off waiting and buying it tomorrow because it will be worth less in your deflationary currency at that point. No one has an incentive to lend their money to others to use it more productively, so no growth occurs. No one buys anything, producers can’t sell anything, and no one can get capital to start any business ventures. The sole, viable way to accumulate wealth is to take the currency and stuff it under the mattress.

This results in a society much like Europe described in a Jane Austen novel, where wealth is simply inherited and the upper class doesn’t actually serve an economic function. They just exist to perpetuate their wealth and dole out subsistence wages to those who work their estates and have absolutely no chance of improving their station.

It’s an inherently broken system and a perfect example of Chesterton’s fence by tech types assuming they know better than everyone else.

throw0101d•42m ago
> Inflation punishes savers and rewards debtors, i.e. it disincentivises the more economically productive behaviour.

Quite the opposite.

Deflation encourages hoarding of cash because it just sits there and increases in value. "If you want to retain the purchasing power of your money, it should participate in society via investment." — Nick Maggiulli

Deflation is built into Bitcoin by design and is one of its most notable features regarding its coin growth schedule. This pros and cons of that approach have been discussed ad infinitum in the crypto community.

The finite nature of btc, low transaction volume, and increasing cost of mining made deflation a given. The original designers simply did not solve this problem. BTC’s dominance in the crypto community suggests that this trait was advantageous for BTCs growth as existing holders are incentivized to add additional use cases/transaction volume.
throw0101d•16m ago

I love how people bring up deflationary spiral as a "peril" while the prerequisite for it is the universal and smashing success of Bitcoin.

The only "problem" Bitcoin poses for economies is for governments to fine-tune their local economies via currency production and related controls. In that sense, we should watch how events unfold in Turkey.

* among major "regular" economies, Turkey has the highest % of people holding crypto (≈20%). Second only to special zones UAE and Singapore (31%, 24%).

* Turkish lira is steadily inflated over the last 30-40 years, well over 10% and recently over 50%.

* Turkey does not have mandate for pricing goods in local currency: you can pay in dollars or euros, along the local lira.

* When you enter Istanbul airport, Every. Single. Gate. is marked with BTCTurk ad, inside and outside - the major crypto exchange in the country.

* Istanbul city market is full of traders who use USDT on Tron.

The experiment of social game "Bitcoin" boils down to this: will the people self-organize the functioning economy with monetary freedom, while the gov loses its grip on it; or will the economy collapse without government's regulation and protective management?

ars•2h ago
> and smashing success of Bitcoin.

It's a success today, we haven't gotten to when they stop issuing any more, and mining is funded by transaction fees. I suspect there are going to be some problems then.

throw0101d•39m ago

Because the authoritarian government took over the previously independent central bank and lowered interest rates. Higher inflation was predicted by mainstream economists, and they were right.

Price is dumping today, i wonder how much of a role this is playing. those coins will be hitting an exchange likely. This has always been the problem with bitcoin.. the implicit assumption is that many coins are lost , but if the early adopters start cashing out, prices will fall fast. Institutional buying and retail is still small relative to the early adopters. There are many people , miners who are quietly siting on huge fortunes.

Most interesting to me is that people are worried about a $2B transaction moving the market.

How does that compare to the market depth of actual currencies or commodities? BTC, being objectively worthless, must be much more sensitive to people wanting to sell I'd expect.

bboygravity•2h ago
How is BTC objectively worthless (I'm guessing you mean "intrinsicly worthlesss"?) as opposed to USD or other major currencies?
anothernewdude•1h ago
Other currencies get their value because the governments that provide them make people pay taxes. If you want to pay the tax the US government charges you, you're going to need some USD - so there's guaranteed demand, and hence intrinsic worth.

There's also other debt that the US government provides in USD - which provides value as well, in the form of bonds.

BTC has no such driver of wealth. Except perhaps money laundering/transfers without AML provisions.

>Other currencies get their value because the governments that provide them make people pay taxes

That's demonstrably false, because countries like Zimbabwe and Venezuela experienced hyperinflation (the complete devaluation of a currency) in spite of the fact that their governments were still forcing people to pay taxes with those currencies. So clearly that alone is not enough to provide intrinsic worth to a currency.

PartiallyTyped•1h ago
The reason for that devaluation is that trust was eroded. GP's premise is correct, that fiat has value because of governments, but the reasoning here is not fully correct. The value is in the trust that the government and the institutions will continue to function properly.
andy99•1h ago
Yeah bitcoin is (at best[0]) a kind of consensual hallucination, worth something because people believe it is. Fiat is someone with a Navy telling you it's worth money, it's very different.

[0] in practice there's a difference between the idea of a distributed digital currency and the ponzi schemes they give rise to I'm real life. Bitcoin is some greater fool thing, it's not a medium of exchange.

analog31•49m ago
This doesn't explain why the currencies of different countries behave differently.

In my view, money is a technology. People use a technology if they find it to be useful. I know this sounds circular, but bear with me. A "major" currency is designed to be useful as a medium of exchange, temporary store of value, and tool of government economic policy. For it to serve these purposes, a government has to moderate its own behavior to some extent.

Thus my view is that the value of a major currency is based, not on the expectation of paying taxes in the future, but on more general expectations of the future behavior of the government.

With that said, paying taxes is good use for money that's a short term store of value, because you rarely need to hold onto your tax money for more than a year before paying it.

PartiallyTyped•1h ago
It's not backed by a government, and while some may say that's a good thing, I think it is not.

Without institutional backing, crypto is just a number in a database that people agree is worth something—for now.

If that collective belief evaporates, there’s no court, no army, no tax base, and no GDP to catch it. Contrast this with fiat currency, which—while not backed by gold—is backed by coercive power and taxation.

Let’s start from something even more fundamental. How do you bootstrap trust? Suppose two pseudonymous entities online want to exchange money for services. Such a system will likely need a reputation system to establish the trustworthiness of entities. That system needs to be tolerant to Sybil attacks (i.e., forging multiple identities), while also ensuring the service provider isn’t exploited by a buyer who refuses to pay after receiving the work.

But this exposes a deeper issue: trust cannot be bootstrapped from scratch. It needs either:

    A shared history (which pseudonyms lack),

    An external authority (which decentralization avoids), or

    A system of credible, enforceable consequences (which requires identity or stake).
Without these, any trust system collapses into a prisoner’s dilemma. Each actor is incentivized to defect (cheat) unless:

    There’s a future cost to cheating (reputation loss that matters),

    There’s a benefit to cooperation over time (e.g. recurring jobs),

    Or there's a credible mechanism to enforce fairness (e.g. escrow and arbitration).
But even escrow only works when dispute resolution is possible and trusted. And dispute resolution requires either a neutral arbitrator (who must have their own identity and incentives) or hard-coded, binary rules, which rarely capture the complexity of creative or service work.

More fundamentally, trust-based systems are built on recursive assumptions:

    You trust X because X has a good rep.

    X has a good rep because others say so.

    You trust those others because…?
Eventually, without a root of trust—whether a state, a court, a verified identity, or long-standing social capital—the entire structure becomes circular. There’s no ground truth. Just reputation built on sand.

And so, the real limitation isn’t crypto per se—it’s that trustless systems don’t exist. At best, we shift trust: from institutions to code, from names to keys, from legal consequences to probabilistic deterrents. But the requirement for trust itself never goes away.

In a pseudonymous setting, the cost of betrayal is minimal. A buyer can stiff a seller and vanish. A seller can deliver garbage or nothing. Reputation can be reset at will unless there’s an expensive cost to identity creation or a strongly linked personal history—which violates pseudonymity.

Thus, bootstrapping trust in such environments is not just technically hard—it is philosophically incoherent without compromising at least one of the pillars: privacy, decentralization, or enforceability.

It follows that if you can’t bootstrap trust, you can’t bootstrap anything that depends on it—including money. Money, at its core, is a social contract, a belief system upheld by collective trust. We accept currency in exchange for goods or services because we trust that others will accept it from us in turn. That belief is reinforced by institutional structures: central banks, governments, legal systems, and ultimately, enforcement mechanisms.

But the moment that trust breaks down, the system unravels. If people no longer trust that their money will hold value tomorrow, they will try to offload it as fast as possible, converting it into hard goods, foreign currency, or anything perceived as more stable. This behavior accelerates inflation—sometimes catastrophically.

We’ve seen this repeatedly in history:

    In Weimar Germany, the collapse of political and institutional trust after WWI led to hyperinflation, with prices doubling every few days.

    In Zimbabwe, trust in government policy collapsed alongside the economy, and the currency became worthless.

    In Venezuela, rampant inflation was fueled not just by bad economic policy but by the public’s loss of faith in any institutional ability to right the course.
The underlying mechanism is always the same: money ceases to function as a store of value when the population no longer trusts the system that issues and manages it. Once the shared illusion cracks, even fiat currency—backed by laws, taxes, and armies—can become just colored paper.

Now contrast that with crypto. Cryptocurrencies claim to solve this by removing central authorities and placing trust in mathematics and distributed consensus. But this is not true trustlessness—it's merely replacing institutional trust with collective belief in code and game theory. And the cracks are showing: when confidence drops, as in market crashes or protocol failures, value disappears just as quickly—if not faster—than in fiat regimes.

So the uncomfortable truth is this:

    Money only works if you believe it will still work tomorrow.
Without enforceable trust, money becomes unstable. Without shared trust, money becomes meaningless.

And that brings us back to the core issue: you cannot build a functioning economy without some root of trust. Whether that root is institutional, social, or cryptographic, it must be anchored, persistent, and costly to betray. If it’s not, the system becomes inherently fragile.

The reason I used pseudonymous here is exactly because we assumed govs are bad. If govs are good, then crypto degenerates to just a slower system for transactions.
