I think Terra/LUNA is probably the right first case for this series.
Not because it was a memecoin. It wasn’t. Terra was more serious than that, which is what makes it more interesting to study. It had a real ecosystem, a huge community, a stablecoin people actually used, Anchor deposits, institutional attention, and a founder who projected a lot of confidence.
That is also what made the collapse so hard for many people to process. It did not look like a random low-cap coin disappearing overnight. It looked like something big enough, complex enough and defended enough that many people treated size itself as a form of safety.
Looking back, that may have been one of the first mistakes.
The basic mechanism was simple on paper. UST was supposed to stay around one dollar. LUNA was the asset used to help absorb volatility and defend that peg. If UST traded below one dollar, people could buy discounted UST, redeem it for one dollar worth of LUNA, and profit from the difference. In theory, that arbitrage should help restore the peg.
The problem is what happens when the market stops believing in the thing doing the absorbing.
More UST redemptions meant more LUNA minted. More LUNA minted meant more selling pressure. More selling pressure made LUNA weaker. And the weaker LUNA became, the less credible the whole defense looked.
That is the part I find most useful about Terra. The mechanism that was supposed to restore confidence became part of the reason confidence disappeared faster.
Anchor is probably the other big piece. A lot of UST demand was tied to the yield. That does not mean every user was stupid or that nothing real existed. But demand for a subsidized yield is not the same thing as durable demand for a stablecoin. If the yield looks less reliable, or the peg starts slipping, that capital can leave very quickly.
This is where I think Terra became less about “can this work in theory?” and more about “what happens if everyone asks for the exit at the same time?”
The warning signs were not all hidden. UST depended on confidence in LUNA. Anchor concentrated demand around yield. The peg had already shown stress before. The community often treated criticism as FUD. And once the peg started needing visible defense, the question changed.
It was no longer just: “Is UST close to one dollar?”
It became: “What is required to keep it there, and is that support still credible under stress?”
That is probably where the read should have changed.
Not when LUNA was already near zero. By then, everyone could see it. The more interesting question is when confidence should have dropped before the collapse was obvious.
For me, that point was when several things started happening together: UST trading meaningfully below peg, Anchor withdrawals becoming important, peg defense becoming visible, LUNA absorbing redemptions while confidence in LUNA was falling, and public explanations relying more on reassurance than on something verifiable.
I do not think the right lesson is “everyone should have known.” That is too easy in hindsight. A lot of people did not understand the mechanism deeply. Some risks were easier to see if you already had a good understanding of stablecoin design, market structure, or reflexive systems.
But I do think there were enough visible signals to reduce confidence earlier.
The misleading signals are probably the most interesting part.
Size looked like safety.
Yield looked like product-market fit.
Founder confidence looked like strength.
Temporary repegging looked like proof the mechanism worked.
Community conviction looked like resilience.
Some of those signals were real in isolation. The mistake was trusting them too much.
That is why I want to start with Terra. Not to say “look how obvious it was.” It was not obvious to everyone. The useful question is narrower: at what point did the Terra read stop deserving high confidence?
For people who followed it before the collapse, what was the first signal that made you reduce confidence?
Was it Anchor, the UST peg, the LUNA minting mechanism, the public defense of the system, the reserves, or something else?
And looking back, which signal looked strong at the time but turned out to be mostly noise?
