Tuga has a cat flap she barely needs. The doors in this house get opened for her anyway, the garden is safe, and nobody is stopping her going anywhere. For her, the flap is a convenience — a nice-to-have that saves me getting up.

Two gardens over, there is a cat who lives entirely outdoors because there is no door she is allowed through. For her, a flap would not be a convenience. It would be the difference between shelter and no shelter.

Most of the bitcoin conversation happens among people in Tuga's position, writing for other people in Tuga's position. We debate store-of-value theses and portfolio percentages from inside economies where the banking system works, the currency is boring, and nobody has ever queued for their own money.

The interesting part of this technology is not happening here.

1. What Breaks First

When a currency fails, it fails in a recognisable sequence, and each step is a door closing:

• Prices stop being meaningful. Shops reprice weekly, then daily. Saving in the local currency becomes an obvious mistake that everyone understands and few can avoid.
• People buy dollars. Physical notes if they can get them, informally, at a rate that isn't the official one. This is the oldest response to inflation on earth and it long predates any of this.
• The government notices. Capital controls follow — limits on buying foreign currency, on withdrawals, on sending money abroad. Not out of malice necessarily; a country losing its currency defends it with the tools it has.
• Now the informal market is illegal, the banks are slow, and your savings are melting.

That sequence is the actual context in which bitcoin gets used as a tool rather than as an asset class. It is not a portfolio decision. It's a way through a closed door.

2. What It Does There

Three concrete things, none of which have much to do with price appreciation:

• Savings that can't be inflated away. Even with bitcoin's volatility, a currency losing a large share of its value annually makes the comparison much less absurd than it looks from a stable economy.
• Sending money home. Remittances are one of the largest financial flows on earth and traditional corridors take a meaningful percentage plus days of delay. Lightning moves value across a border in seconds for a negligible fee, at any hour, without either party having a bank.
• Money that isn't in anyone's system. Savings that can be carried in your head across a border, or held where an account freeze doesn't reach. This sounds abstract until you've had an account frozen.

3. The Honest Complications

This is where a lot of writing on the topic becomes advertising, so:

• In practice, most people there use stablecoins, not bitcoin. If your problem is that your currency is losing value weekly, what you want is dollars — and a digital dollar on a crypto rail is closer to what you need than a volatile asset. The rails get used enormously. Bitcoin specifically is the smaller share of that usage, and pretending otherwise is a fantasy.
• Volatility is a genuine problem for someone poor. Telling a person whose savings are the difference between eating and not that they should accept a 70% drawdown is not advice, it's ideology. This is precisely why stablecoins win the day-to-day.
• It requires infrastructure. A phone, data, electricity, and enough literacy with the tools not to get robbed. Those are not universal, and the people worst affected by a currency collapse often have the least of all four.
• Scammers concentrate where desperation is. A population newly seeking alternatives is a target-rich environment, and the fake-platform operators know it.
• Legality varies and changes. Some governments accommodate this, some prohibit it, and the rules move. The people using it are often taking a real legal risk, which is easy to romanticise from a country where you aren't.

4. Why It Still Matters

With all that said — and I mean all of it — something is true here that isn't true anywhere else in this technology.

It's the only use case where the alternative is genuinely worse. In a functioning economy, bitcoin competes with a bank account that works fine. Self-custody is a philosophical preference. In an economy where the currency is failing and the borders are closing, it competes with losing your savings, and the comparison stops being philosophical.

That's also, in my view, the most informative adoption signal there is. Usage driven by necessity is harder to fake, harder to incentivise, and far more persistent than usage driven by upside. If you want to know whether this technology is becoming what its advocates claim, watch the places where people have no better option — not the places where it's a talking point.

The Point

Tuga's flap is a luxury. She would be fine without it, and if it jammed tomorrow she'd sit at the door and complain until somebody came.

The cat two gardens over doesn't have that fallback, and for her the same piece of hinged plastic is the whole difference. Same object, completely different meaning, decided entirely by whether the doors open for you anyway.

Most of us writing about bitcoin have doors that open. It's worth remembering that the strongest case for the thing we're discussing belongs to people who don't — and that they're usually not the ones being asked.

The flap matters most where the door doesn't open. 🐾⚡

Nothing here is financial advice — I feed a cat and write about Bitcoin, which qualifies me to advise you on neither. Legal treatment of crypto varies enormously by country. Do your own research.
