Vitalik Buterin denounces the Bitcoin stock‑to‑flow price model, citing its miss on $100k forecasts while BTC hovers around $21,500, up 5% in 24 h.
Vitalik Buterin labeled the Bitcoin stock‑to‑flow (S2F) model “false” and “harmful” on Tuesday, a criticism that coincided with Bitcoin’s price rebounding to roughly $21,500—a 5% gain over the previous day【2】. The move comes as the model’s long‑standing $100k‑plus price target for 2022 remains unfulfilled, raising questions about its predictive value.

Buterin’s critique aligns with a broader backlash against the S2F framework, which predicts Bitcoin’s price from its circulating supply (“stock”) relative to the annual mining output (“flow”). The model, devised by analyst PlanB, had previously projected Bitcoin could reach $288,000 by the end of 2024, and specifically $100,000–$110,000 in 2022. The latest market crash pushed BTC to an 18‑month low below $20,000, far short of those expectations【1】【2】. By calling the model “harmful” and “deserving of mockery,” Buterin suggests that such deterministic forecasts give investors a false sense of certainty【4】.
PlanB acknowledged that the S2F model enjoyed a “good run” from March 2019 to March 2022, but its trajectory diverged after the end of last year when Bitcoin failed to breach the $100k mark【1】【3】. He now posits two possibilities: Bitcoin is severely undervalued and may rebound, or the S2F approach will lose relevance【1】【3】. The current price of $21,500 sits well below the model’s June‑18 projection of $67,175, underscoring the widening gap between forecast and market reality【4】.
The recent 5% price uptick reflects a modest recovery after the prolonged slump, yet volatility remains high. Critics, including EthHub co‑founder Anthony Sassano, have labeled S2F an “epic failure,” echoing Buterin’s sentiment that financial models promising inevitable price rises are misleading【1】【2】. The debate highlights a broader tension in the crypto community between quantitative models and the unpredictable dynamics of market sentiment, regulatory news, and on‑chain activity.
Buterin’s dismissal of the S2F model underscores a growing skepticism toward deterministic price forecasts in crypto. Whether Bitcoin’s price will rebound to justify the model’s long‑term optimism, or the framework will fade as a useful tool, remains an open question that the market will answer in the weeks ahead.

A higher S2F ratio means the asset's existing supply is large relative to its annual new production, implying greater scarcity and potentially a premium over time.
Each halving cuts the annual flow of new bitcoins in half, which roughly doubles Bitcoin's S2F ratio and signals increased scarcity.
Critiques focus on its omission of demand factors, sensitivity to regime shifts, and tendency to overfit historical price patterns.
Yes, it originated with commodities like gold and silver and can be applied to any asset with a predictable, limited issuance, though demand still drives price.
Sources describe it as a scarcity lens rather than a price oracle; it should be combined with other metrics and risk controls for investment decisions.
