Key terms

Stock-to-Flow (S2F) model

PlanB's 2019 model fitting Bitcoin price to its stock-to-flow ratio (existing supply / annual new supply). Predicted $98K BTC for Nov 2021 (actual peak $69K) and $100K-$1M for 2022 (actual low $15K). Failed in out-of-sample period.

PlanB

Anonymous Dutch institutional investor; popularized stock-to-flow model in 2019. Acknowledged S2F was not tracking by mid-2022. Now characterized as "bull-market only model" by some advocates.

Bitcoin obituary

Public claim that Bitcoin is dead, dying, or fundamentally broken. 99bitcoins.com tracks 477+ such obituaries since December 2010. Pattern: published most often near drawdowns; quietly forgotten when next cycle prints higher highs.

Tim Draper $250K prediction

VC Tim Draper has predicted Bitcoin reaching $250,000 since 2018 (originally for 2022). Extended to mid-2023, end-2023, 2025, and most recently 2026-2027. Number kept; date moved ~5 years across multiple extensions.

"Ethereum killer" genre

Recurring marketing label for L1 chains positioned as Ethereum replacements. Examples: EOS, Cardano, Polkadot, Algorand, Avalanche, Solana, Sui, Aptos, Sei, Monad. None has displaced Ethereum's ecosystem depth as of 2026.

"Blockchain not Bitcoin" thesis

2017-2018 enterprise narrative: blockchain technology is revolutionary but Bitcoin specifically is unimportant. Most enterprise blockchain consortiums (IBM Blockchain, JPMorgan Quorum derivatives, Hyperledger) faded by 2022-2024. Public chains (Bitcoin and Ethereum) ate the actual on-chain economy.

NFT collapse (2021-2023)

NFT trading volume fell ~95% from August 2021 peak (~$25B/month) by 2023. Floor prices for iconic collections (CryptoPunks, BAYC) fell 95-99% from peaks. Enterprise NFT initiatives mostly shut down. Survived: Bitcoin Ordinals niche, selective high-art markets.

Metaverse pivot (2021-2024)

Meta renamed from Facebook in Oct 2021; committed $10B+/yr to metaverse. Reality Labs cumulative losses ~$50B by 2024. Horizon Worlds peaked under 200K MAU. Zuckerberg pivoted to AI in 2023-2024. Microsoft and Disney closed metaverse divisions in 2023.

El Salvador rollback (Jan 2025)

IMF deal effectively rolled back Bitcoin's legal-tender status. Bitcoin acceptance became voluntary; taxes payable in dollars only; government Bitcoin operations curtailed. Original "wave of bitcoinization" thesis did not play out (no other country followed).

Ethereum 2.0 timeline slip

Original 2018-2019 ETH 2.0 roadmap projected Phase 0 by 2019, full sharding by 2021. Beacon Chain actually launched Dec 2020; the Merge Sept 2022; full danksharding still pending in 2026. Off by 3-5 years.

"This time is different" pattern

Recurring claim at every cycle peak that the typical post-peak drawdown will not happen this cycle. 2017 ("institutions"), 2021 ("DeFi/NFTs/Tesla"), 2024-2025 ("ETFs/GENIUS/Strategic Reserve") — each had a partial truth but cyclical drawdowns happened anyway.

"Third time" filter

Practical heuristic: when evaluating a confident crypto prediction, ask whether the same prediction has been made by previous cycles' advocates. Recurring predictions ("ETH killer," "this is the new internet") have low base rates of working out.
