Six Demand Pipes: I Spent Millions on Hackathons in Five Countries and Bought Only Fake Demand

If you work in payments, wallets, exchanges, or cross-border collections—or you’re weighing whether to issue your own stablecoin—start with the most expensive question in this business, the one most people skip: where does demand actually come from?

Most people compare two stablecoins on reserve transparency, audits, on-chain speed. That’s looking at a distribution business through a product manager’s eyes. The rookie illusion is treating it as a persuasion contest—whoever is more credible, more compliant, faster, wins. Wrong. Demand isn’t persuaded into existence. It’s structurally defaulted into existence.

Written as an equation you can actually compute:

Demand = Defaults × Network Effects.

The currency that pops up when you deposit, the quote asset of a trading pair, the first balance on a wallet’s home screen—these “defaults” aren’t chosen by the issuer. They’re configured by the channel. Network effects then harden it: the more people use USDT, the less a newcomer can avoid it, and the default compounds on itself. Multiply the two, and you see why “build a better coin” almost never works—you’re improving a product while your opponent occupies the structure.

The Six Demand Sources: A Ruler for Whether a Stablecoin Lives or Dies

A stablecoin’s real demand flows in through exactly six inlets:

1. Exchange quoting—the hardest pipe. Switching the quote currency forces an entire market to relearn prices; migration cost is enormous. This is Tether’s deepest moat.
2. Market-making and OTC settlement—first to occupy, locks it down. Invisible to retail, yet it’s the water gauge of the whole market.
3. DeFi collateral—real demand, but yield-sensitive and low-loyalty. The pipe most easily misread as “people are using it” when often it’s just “people are arbitraging it.”
4. Wallet payments—closest to consumers, but today mostly a “transfer medium,” not a “payment habit.” Biggest potential, slowest to cash in.
5. Cross-border B2B—the most underrated pipe. The killer feature isn’t “fast”; it’s “routes around banking relationships you could never get.” It lets a small Chinese factory receive dollars directly from a Latin American buyer, without begging for a correspondent-banking channel it could never build.
6. RWA / institutional inflows—clearer compliance boundaries since the GENIUS Act, but the valve on this pipe sits with regulators. Institutions want clean compliance lines; they won’t take legal risk for an extra 0.5% of yield.

Picture six pipes feeding one pool—the pool is circulating supply. As of June 2026, total stablecoin market cap is about $316B; USDT alone holds about 58.9% (~$186.7B), USDC about $75B, the two together about 82.8%. That concentration is no accident—USDT’s dominance isn’t one unusually thick pipe. It’s all six pipes, occupied.

This hands you a ruler more useful than reading audit reports: to judge whether a stablecoin lives or dies, first count how many pipes it occupies, then check how deep each one runs. Occupy one pipe so firmly nobody can dislodge you, and you can survive. Occupy none and run on incentives alone, and you’re the next corpse.

I Spent Millions Verifying the “Fake Pipe” Firsthand

I didn’t learn this from the spectator seats. I paid for it.

In 2018–2019, building the HPB public chain, we pushed signature verification to roughly 30,000 TPS—technically, we lost to no one. I also believed a formula that looks naive today: make the tech good enough, add generous subsidies, and developers and applications will come. So we went global—the US, China, Canada, the Netherlands, South Korea—running hackathons and local ecosystem campaigns country by country, several million dollars in total. And it was genuinely lively: project sign-ups, packed venues, on-chain activity—everything looked great short-term.

Then time stretched out, the subsidies wore off, and retention went to essentially zero.

It took me a while to see it clearly: I had bought activity, not demand. Those teams came not because their business couldn’t survive without my chain, but because I was handing out money. I had never made myself the default they couldn’t route around—I had merely short-leased their attention. I paid this tuition so you don’t have to: if your circulation curve is fed by subsidies, it isn’t a moat—it’s an invoice that can come due at any moment.

The Most Expensive Specimen: UST’s Public Autopsy

The industrial-scale version of the same mistake is UST. Anchor’s near-20% yield bloated the “DeFi collateral” pipe—people moved money in not because they needed the coin, but because they wanted the interest. The money was borrowed, not earned. When reflexivity kicked in (May 2022), the entire ~$50B ecosystem went to zero within a week, and that bloated pipe was the first to snap—in front of everyone.

That wasn’t a depeg accident. It was the public autopsy of a fake pipe. What it proved is plain: demand bought with yield carries yield as its expiration date.

The Flywheel—and the One Realistic Play for a Newcomer

The six demand sources aren’t six islands. They’re a self-spinning flywheel: exchange quoting brings liquidity depth → depth pulls market makers and OTC desks to settle in it → settlement volume makes it the default DeFi collateral → wallets integrate it by default → cross-border B2B and institutions dare to use it → the more people use it, the more exchanges must keep quoting in it. One full turn, back to the start—stronger. A newcomer isn’t facing “a rival coin.” It’s facing a machine that’s accelerating itself.

So a new coin that tries to grab all six pipes is almost guaranteed to end up shallow in all six, all of them dangling on subsidies. The realistic play: punch through one pipe, hold it so firmly nobody can move you, then ride the flywheel’s momentum into the adjacent one. Which pipe? The one where you already hold the default configuration. If you’re a payments company, start from wallet payments; an exchange, start from quoting; a trade SaaS, start from cross-border B2B. That way you’re attacking structure, not buying activity—and you sidestep the exact hole I fell into.

The peg keeps you alive; distribution lets you win; and distribution flows from demand—counting how many pipes you occupy tells you more about whether this coin still exists in three years than counting the pages of your audit report.

If you’re building—or evaluating—a stablecoin: of the six pipes, how many do you truly occupy? And which one do you already hold the default configuration for? Tell me in the comments.
