As far as I know, nowhere in the Bitcoin white paper or the original code base. Does it say anything about what you seem to think it's use cases are.
Bitcoin has one main use, digital cash, that can be sent instantly and for free or a very low fee.
Edit: I would agree though, that anything other than that is probably a scam.
The original theory of Bitcoin was, as described in the paper, decentralized digital cash. But in practice it was never optimized for what normal people use cash for. As system like that would be something like M-PESA.
Even at the time, cash was declining in usage. In the 18 years since, it has declined a lot more. And for good reason, because what most people want for most things isn't digital cash, but digital money. E.g., debit cards and Venmo.
So pretty naturally Bitcoin has value only for a few niche use cases that are not well served by more effective systems. Various sorts of crime, mostly. Digital cash, sure, but the kind that's transferred in unmarked envelopes slid quietly across the table. The kind that is delivered in a briefcase.
As a side note, it also failed in its goal of being decentralized. The mining power is very concentrated. Much more so than the banking industry, for example. And most users keep their Bitcoin on deposit in centralized services. So it's again basically banking but worse.
Look at china where if you have a large company and take a stand against the government all your equity will be wiped out and you will be either imprisoned or banished to another country.
Cash in a government bank account is the same way, you can wake up one day and all your assets will be seized, your credit cards will stop working.
Bitcoin works because you can technically have your wealth memorized. You can memorize a string of charcters that allow you to bring money with you no matter where you go. NO government or other human can steal it from you (except through torture) but you can also easily not memorize it and instead distribute the keys throughout the world in opposing countries meaning even if you are attacked by one country you still have some wealth kept in another.
A store of wealth is what bitcion allows. True freedom from governments stealing your money because you have ideas which they do not agree with.
This in my mind is the main usage of bitcoin.
Other coins like stablecoins, or the btc lightning network have high value because they make transactions much cheaper as traditional banking systems are complex, error prone, and costly.
It's also terrible at that. Bitcoin is down by something like half off its peak. The odds of me losing money to "government intervention" if I'm not actively criming, are quite low. Certainly well under 50%.
> Bitcoin works because you can technically have your wealth memorized.
If you are having to reach for increasingly absurd fantasy scenarios to justify something that was supposed to have thoroughly quotidian users, maybe you should take that as a sign?
> because you have ideas which they do not agree with
Oh, that's who's using bitcoin the most? Philosophers and the like? I had no idea.
For some definition of "actually", given how much it has dropped recently. When he was still a just a candidate, the current Opposition leader in Canada was very excited about Bitcoin:
> As Poilievre campaigned for the Tory leadership on the way to a landslide victory, he spoke positively about decentralized finance and cryptocurrency. At one point, he argued that crypto would allow Canadians to "opt-out" of inflation, which was soaring at the time. And he famously used Bitcoin to purchase a shawarma at a London, Ont., restaurant in March 2022.

> In 2022, when Pierre Poilievre was a Conservative leadership candidate, he said he’d make Canada the crypto capital of the world. According to him, the Bank of Canada was “ruining” the Canadian dollar, printing money and ramping up inflation to fund COVID-19 relief. His solution? Give Canadians crypto as an alternative currency.

Given the noise that was made about inflation at the time and the (alleged) devaluation of the CAD, I'm curious to know what the inflation rate equivalent would be now (Feb 2026) if Bitcoin is used as the monetary base.
This applies to a great deal, not just bitcoin.

Bitcoin CAN be used as a store of wealth and the slowness actually makes it better as the slowness is part of the same process that makes it safer, harder to hack/takeover, and gives it value.
You should not look at all crypto as one thing.
Fees have historically gone up above $100 per transaction. They've since added hacks on top of the original Bitcoin protocol to get the price back down again, but the original design was not good for low fees.
And transactions can take 30 minutes or more to settle, that's hardly instant. If you accept a transaction instantly, it's relatively easy for someone to scam you by double spending.
So, no, Bitcoin doesn't make a great digital cash. Maybe a better wire transfer. But the biggest benefit of it is to be unblockable and unrefundable, which makes it great for scames and illegal activity, plus the speculative nature of the pricing, which is great for gambling on.
Only question is, if Elizabeth Stark knows it's unworkable slop why does she keep raising money for it???
There are any number of other popular coins out there that have the same or better liquidity as BTC that charge tiny fractions of the fees. And also settle in seconds.
You're saying Bitcoin like BTC, but the parent commenter was probably referring to the giant ecosystem of coins, that happens to include BTC, but also many other much faster and cheaper options, that are used to globally remit payments every day.
What it's replacing, by the way, Western Union, Wise and the like, is also pretty unblockable and unrefundable.
And yeah, the thing is, payment systems that work approximately as well as BTC exist without being cryptocurrency and using up so much electricity on mining. The main difference is that they don't operate in some areas where BTC still can (like evading sanctions, like this), and the speculative nature of BTC (which is actually a net negative on using it as a cash).
So it's cheaper to use Paypal ?
So now it's back to being cheaper than Paypal, but yeah, there was a time when there were $100+ transaction fees. And it may hit that again if transaction numbers go up enough to fill up blocks with the new implementation.
