Stablecoins & CBDCs

The internet needs money native to it — and the incumbents know it. Two very different “digital dollars” have emerged, and it’s vital not to confuse either with Bitcoin. One is private (stablecoins like USDT and USDC); one is the government’s own (a central bank digital currency, or CBDC). Both put ordinary fiat onto fast modern rails. Neither fixes what’s actually broken about fiat — and one of them makes it far, far worse.

Stablecoins — a dollar on a blockchain

A stablecoin is a token pegged one-to-one to a currency — almost always the US dollar — issued by a company that claims to hold matching reserves of cash and government bonds. Because they live on blockchains, they move across the world in seconds for cents, which makes them genuinely useful: for someone in Argentina, Nigeria or Lebanon watching their local currency melt, a stablecoin is a lifeboat — a way to hold dollars without a US bank account. That real demand is why they’ve exploded across the global south.

But be clear about what it is: still fiat. It’s a dollar, so it still loses value every year to inflation. And it’s centralised — the issuer can freeze your tokens on request (both Tether and USDC have blacklisted addresses), and you are trusting that their reserves are real and fully backed. A stablecoin is an IOU from a company. Even holding the keys doesn’t fully protect you, because the issuer can blacklist the coin itself. Tellingly, stablecoin issuers have become some of the largest buyers of US government debt — so far from challenging the dollar, they prop it up. A stablecoin is a feature of the fiat system wearing crypto’s clothes.

CBDCs — programmable money the state controls

A central bank digital currency is the government issuing digital money directly to citizens, with no commercial bank in the middle. China’s e-CNY is the furthest along; most of the world’s central banks are now piloting one. They’re sold with friendly words — convenience, efficiency, financial inclusion, “modernising money.” The reality is the most powerful tool of financial control ever proposed, because the same authority issues every unit and can see, and shape, every use of it:

• Total surveillance — every transaction visible to the issuer by default. The quiet privacy of cash simply disappears.
• Programmability against you — money can be designed with rules baked in: expiry dates to force you to spend, limits on what you’re allowed to buy, caps, or spending that only works in certain places.
• An individual off-switch — a protester, dissident or out-of-favour group can have their money frozen or drained instantly, with no court and no bank in the way. In 2022 Canada froze the bank accounts of protesters and their donors; a CBDC turns that from a legal process into a single keystroke.

A CBDC isn’t new money at all. It’s the same inflating fiat, plus a control layer that physical cash never had. It is, quite precisely, the endgame of the war on cash.

The three, side by side

• Bitcoin — no issuer, fixed supply, permissionless; it cannot be frozen, printed, or programmed against you. It’s your money.
• Stablecoin — a private issuer, an inflating fiat peg, freezable, backed by reserves you have to trust. A useful dollar lifeboat, but ultimately an IOU.
• CBDC — a state issuer, inflating fiat, surveilled and programmable and freezable by design. Control dressed up as convenience.

Why this distinction is everything

You will be told, again and again, “the government has digital money now too — you don’t need Bitcoin.” It’s the exact reverse. A CBDC is the most complete system of financial control ever devised, and Bitcoin is the one antidote to it: a money no state can watch, freeze, or inflate. If a single idea from this lesson stays with you, make it that one.

And a currency the issuer can watch, freeze and switch off is the perfect instrument for a project that’s already quietly underway — the abolition of cash itself. That’s next.

Key takeaways

• Stablecoins (USDT/USDC) are private dollars on a blockchain — a genuine lifeboat for people escaping a collapsing local currency, but still inflating fiat, freezable by the issuer, and an IOU you must trust is fully backed. They prop up the dollar rather than challenge it.
• A CBDC is government fiat plus a control layer cash never had: default surveillance, programmability (expiry, spending limits) and an individual off-switch. Same technology as Bitcoin, opposite purpose — Bitcoin removes the controller, a CBDC perfects it.
