🪦 The coin graveyard
Well over a hundred thousand cryptocurrencies have died — most quietly, some spectacularly. These are the instructive ones: coins that were worth billions before design flaws, fraud or simple arithmetic caught up with them. Each carries a lesson that's cheaper to learn here than the way their holders did.
An "algorithmic stablecoin" that held its US$1 peg with financial engineering instead of reserves, paired with Luna, a top-ten coin at its peak. When the peg slipped, the mechanism that was supposed to restore it minted Luna hyperbolically instead — tens of billions of dollars of value evaporated in about a week, taking lenders and funds down with it. Founder Do Kwon was later arrested abroad and extradited to face US fraud charges.
The lesson: A yield that requires the token never to wobble is not stability — it's a coiled spring. "Algorithmic" backing has failed every time it has been tested at scale.
Promised roughly 1% daily returns from a "trading bot" that never existed — the classic ponzi arithmetic, dressed in crypto. At its peak BCC was a top-20 coin worth billions. It collapsed within hours of shutting its lending platform, falling over 90% in a day. US authorities charged its promoters; its founder was indicted and remains a fugitive.
The lesson: 1% a day is 3,678% a year. Any platform quoting returns like that has told you what it is — the only question left is when.
Marketed worldwide as the "Bitcoin killer" and sold through multi-level marketing, OneCoin raised over US$4 billion — for a coin that never had a functioning public blockchain at all. The price shown to investors was simply typed into a database. Founder Ruja Ignatova, the "Cryptoqueen", vanished in 2017 and sits on the FBI's Ten Most Wanted list.
The lesson: If you can't verify a coin exists on a public blockchain — with your own eyes, on a block explorer — it may not exist at all.
The loyalty token of the FTX exchange, once valued in the billions. When leaked documents showed FTX's sister fund was propped up by the exchange's own token, confidence — and the token — collapsed in days, revealing that customer deposits had been quietly loaned out. FTX filed for bankruptcy; founder Sam Bankman-Fried was convicted of fraud.
The lesson: An exchange's own token is a bet on the exchange itself. Held on that same exchange, it's the same risk twice.
"Unbank yourself" — Celsius offered up to ~17% yield on crypto deposits, funded by increasingly risky bets with customer coins. It froze withdrawals in June 2022 and went bankrupt weeks later, trapping billions in customer funds. CEO Alex Mashinsky pleaded guilty to fraud and was sentenced to prison.
The lesson: Yield always comes from somewhere. When a platform pays far above market rates, the missing risk hasn't vanished — it's been transferred to you.
A 2021 memecoin phenomenon that charged a 10% tax on every sale, half "locked forever" in a liquidity pool. US authorities alleged executives took millions from that supposedly locked pool for houses and sports cars. The SEC and DOJ filed charges in 2023, the company went bankrupt, and an executive was convicted of fraud.
The lesson: "Locked liquidity" is only as good as who holds the keys. Tokenomics you can't independently verify are marketing, not maths.
Rode the Netflix show's hype to a 40,000% gain in days — while its contract quietly prevented most holders from selling. The developers then cashed out and vanished with millions, taking the website and social accounts with them. The whole arc, launch to zero, took about two weeks.
The lesson: Before buying any small token, check you can sell it. A price that only goes up because nobody can exit isn't a price.
An Australian token marketed to small businesses as spendable and readily exchangeable. ASIC took issuer BPS Financial to the Federal Court, which found it had made false or misleading representations about Qoin and operated unlicensed. A home-grown reminder that "accepted by thousands of merchants" claims deserve the same scrutiny as any offshore token.
The lesson: Australian regulation now has teeth — but a court finding comes after the money is spent. Check claims before buying, and check the AFSL tracker before trusting any platform.

FAQ
How many cryptocurrencies have died?
Serious estimates run well past 100,000 — and if you count every token ever minted on decentralised exchanges, into the millions. Most die quietly of illiquidity rather than spectacularly by fraud: no buyers, no volume, no exit. The famous collapses on this page are the visible tip of a very large iceberg. Our count of how many coins exist puts the numbers in context.
Can a dead coin come back?
Almost never meaningfully. A price can twitch — dead coins with thin liquidity are favourite playgrounds for manipulation — but a project without developers, users or an issuer doesn't recover; it just trades as a lottery ticket on its own corpse. "It's so cheap now" has been the epitaph on a lot of portfolios.
Are my losses on a dead coin tax deductible?
Generally you need a CGT event to claim a capital loss — simply watching a coin go to zero isn't one. If it still trades anywhere, selling realises the loss. If it's genuinely worthless and unsellable, the ATO has processes for declaring worthless assets, best confirmed with a tax agent. Realised losses offset gains — this year's or carried forward.
How do I avoid the next one?
Every collapse on this page telegraphed at least one warning: yields far above market, tokenomics that punish selling, unverifiable claims, or a platform holding everything. Our scams hub covers the patterns, and the 12 lessons in the learn path build the checking habit. None of it requires expertise — just the willingness to look before buying.
