Everybody knows the picture: a cat, a saucer of milk, contentment. It is also, as any vet will tell you, mostly a bad idea — adult cats are largely lactose intolerant and the thing in the picture causes problems that the picture never shows.

The saucer isn't evil. It's useful, it's popular, it solves an immediate problem, and the cost arrives later and quietly.

Stablecoins are the saucer of this industry. They are the most-used product in crypto by a distance, they genuinely solve the problem people actually have, and almost nobody holding one could tell you what it is.

1. It's an IOU

A stablecoin is not digital money. It's a token representing a promise that someone will give you a dollar for it.

That promise has a promiser. Which means the whole thing rests on three questions:

• Does the issuer actually hold the reserves?
• Are those reserves the kind of thing that can be sold quickly at full value in a panic?
• Will the issuer honour redemption for you specifically, or only for large institutional clients?

Notice that none of these are questions about blockchains. The token moves on a public network, which is the part that works beautifully. The value of the token is a traditional credit question about a company, and no amount of cryptography helps with it.

2. The Varieties

• Fiat-backed. The dominant model: a company takes dollars, issues tokens, invests the dollars mostly in short-term government debt, and keeps the interest. This is a profitable business, which is why the business exists. Quality depends entirely on what's actually in the reserve and who verifies it.
• Over-collateralised crypto-backed. Locked crypto collateral worth more than the tokens issued, with automatic liquidation when it falls. No company holding dollars — but it inherits whatever risk lives in the collateral and the liquidation machinery.
• Algorithmic. No meaningful collateral; stability maintained by a mechanism. The prominent attempt at scale collapsed catastrophically in 2022, taking enormous value with it. Approach anything in this family with the assumption that the mechanism has not been tested by the scenario that matters.

"Stablecoin" names a goal, not a design. Two tokens both worth a dollar can be entirely different objects.

3. The Button Nobody Mentions Until It's Pressed

Major fiat-backed issuers can freeze tokens at specific addresses. They do it in response to law enforcement, sanctions, and large thefts.

This happened in the Ledger reseller case: the issuer moved to freeze part of the stolen funds. For those victims, that's unambiguously good — a recovery that bitcoin, by design, cannot offer.

And it is also the complete description of what you're holding: an asset whose balance someone can edit. Not through a hack. Through a normal administrative action, by design, from a dashboard.

You cannot have the freeze available for your theft and unavailable for everything else. It's one switch. Whether that's a feature or a defect depends entirely on which side of it you're standing — but it is not optional, and anyone presenting these as "censorship-resistant digital dollars" is describing something that doesn't exist.

4. Why They Win Anyway

Here's the part bitcoin-only writing tends to skip, and I wrote about it in the article on currency collapse.

For someone whose local currency loses a large share of its value every year, the question is not "bitcoin or dollars". It's "how do I hold dollars at all, when my bank can't, my government restricts it, and the informal market is risky?" A stablecoin on a crypto rail answers that, today, from a phone, for a negligible fee.

That's why usage is enormous and why most real-world crypto payment volume in struggling economies is stablecoins, not bitcoin. The volatility that a saver in a stable country can tolerate is unacceptable to someone whose margin is their next month, and pretending otherwise is a luxury position.

5. How to Hold Them, If You Do

• As a rail, not a residence. Fine for moving value and for sitting briefly between trades. A long-term savings balance in someone else's liability is a different decision, made without noticing.
• Know which issuer and what backs it. They are not interchangeable, and the differences only matter on the one day they matter enormously.
• Spread them if the amount is meaningful. Issuer risk is concentrated risk.
• Understand the depeg pattern. They mostly trade at a dollar, right up until liquidity in one venue dries up and the price gaps. The gap is where the losses happen, not the slow drift.
• Remember the chain and the token are separate risks. The network can be fine while the issuer is the problem, and vice versa.

The Point

The saucer isn't a scandal. It's convenient, it's popular, the cat enjoys it, and every so often somebody pays for it in a way the picture never showed.

Stablecoins do a real job and do it better than the alternatives available to the people who need them most. They just aren't the thing their name suggests — they're a company's promise, moving on a network that has nothing to do with whether the promise is good.

It's an IOU on a fast rail. Know whose, and don't live in it. 🐾⚡
