The Emerging Narrative
Bitcoin is trading at $45,301 on February 8, 2024, recovering nearly all losses from the post-ETF sell-off, and the widely followed Stock-to-Flow analyst known as PlanB is making a bold declaration: the flagship cryptocurrency may never again fall below $40,000. The claim is rooted in a rigorous analysis of Bitcoin realized price metrics across multiple timeframes, and it arrives as institutional inflows into spot Bitcoin ETFs continue to shatter records.
The crypto market capitalization has surged to $1.72 trillion, representing a 3.12% increase in 24 hours. Bitcoin itself has gained 2.22% on the day and 5.17% over the past week, pushing past the psychologically important $45,000 level for the first time since the ETF-driven correction began in mid-January. The recovery has reignited bullish sentiment across the market, with altcoins like BNB (+3.65%), ADA (+5.48%), and SOL (+1.79%) all posting significant gains.
Catalyst Identification
PlanB, the pseudonymous Dutch analyst whose Stock-to-Flow model has been one of the most closely watched frameworks in the crypto space since 2019, published his analysis on February 8 via social media. The core argument centers on Bitcoin realized prices at different time horizons. The overall realized price currently sits at $23,000, up from the previous month. The 2-year realized price has climbed to $32,000, and critically, the 5-month realized price now stands at $40,000.
Realized price represents the average cost basis of all coins in circulation — essentially what the entire market paid for its Bitcoin. When the market price trades above all realized price levels, it signals that the vast majority of holders are in profit, which historically reduces selling pressure and creates a supportive floor. PlanB emphasized that realized prices across all timeframes are increasing simultaneously, a condition he describes as “very bullish.” The 5-month realized price of $40,000 has previously served as a floor during bull market dips, marked by what PlanB identifies as red arrows on his charts.
Key Players to Watch
The macroeconomic backdrop is adding weight to the bullish thesis. Bitget released a comprehensive study forecasting Bitcoin could reach $150,000 in the near future, more than doubling its previous all-time high of $69,000. Robert Kiyosaki, author of Rich Dad Poor Dad, has echoed a similar price target, lending mainstream credibility to the optimistic outlook.
Fundstrat founder Tom Lee, one of Wall Street’s most prominent Bitcoin bulls, maintains his forecast of $100,000 to $150,000 for 2024, with an even more ambitious $500,000 target by the end of the decade. Lee’s projections factor in the halving supply shock, growing institutional adoption through ETFs, and broader macroeconomic tailwinds including potential Federal Reserve rate cuts.
The spot Bitcoin ETF market continues to serve as a powerful demand engine. On February 8, the ETFs recorded $403 million in single-day inflows, demonstrating sustained appetite from traditional finance. BlackRock’s iShares Bitcoin Trust (IBIT) and Fidelity’s Wise Origin Bitcoin Fund (FBTC) lead the pack, collectively absorbing billions in assets since their January 11 launch.
Risk Assessment
Despite the optimistic projections, investors should consider several risk factors. PlanB’s Stock-to-Flow model has faced criticism for missing the mark on timing and magnitude in previous cycles. The January correction from $49,000 to $38,500 following the ETF launch demonstrated that even structurally bullish environments can produce sharp drawdowns. The 5-month realized price floor has not been tested in a sustained bear market scenario with the current level of institutional involvement.
Regulatory uncertainty persists, with the SEC’s approach to crypto enforcement remaining aggressive. Macroeconomic headwinds, including potential inflation surprises or delayed rate cuts, could pressure risk assets broadly. Bitcoin’s upcoming halving in April 2024, while historically bullish, introduces a period of uncertainty as miners adjust their operations to reduced block rewards.
Strategic Conclusion
PlanB’s analysis provides a compelling framework for understanding Bitcoin’s current price dynamics. With realized prices rising across all timeframes and the $40,000 level establishing itself as a structural floor, the risk-reward profile for Bitcoin exposure appears favorable. The combination of ETF-driven institutional demand, approaching halving supply shock, and broadening mainstream acceptance supports the case for continued appreciation.
However, prudent investors should view the “never below $40K” claim as an informed thesis rather than a guarantee. Historical data supports the realized price floor concept, but unprecedented market conditions — including the largest Bitcoin ETF inflows in history and an evolving regulatory landscape — mean past patterns may not perfectly predict future outcomes. Position sizing and risk management remain essential even in structurally bullish environments.

planB called 100k by 2021 too, lets maybe chill with the never below 40k calls
to be fair the s2f model called the general trajectory right even if the price targets were off. the floor thesis based on realized price is a different argument
moonboi_ fair point on the 100k miss but the realized price thesis is fundamentally different from S2F. its based on actual on-chain cost basis not a stock-flow regression
realized_floor_ fair distinction between realized price and S2F. but on-chain cost basis didnt help anyone in cascading liquidation events either
moonboi_ has a point. PlanB called 100k too, maybe temper the ‘never below 40k’ calls.
Moonboi_ is right – PlanB called 100k too. Maybe temper the ‘never below 40k’ calls.
Moonboi_Skeptic PlanB also said $100K by 2021. S2F model has been wrong more than a coin flip and people still quote it
Realized price as a floor makes sense on paper but black swan events dont care about your metrics
^ this. realized price didnt help anyone when ftx imploded
ETF inflows are the real story here. 859k BTC absorbed and counting. The supply shock is real even if PlanB’s model is debatable.
859K BTC absorbed through ETFs in a few months. the demand side has fundamentally changed since planb first wrote the s2f model
859K BTC absorbed through ETFs in months. The demand side has fundamentally changed.
planb calling never below 40k again lines up with realized price metrics and those 859k btc etf absorbs
PlanB conveniently switches from S2F price targets to realized price floors right when his original model failed. $45K recovery doesnt prove $40K is untouchable
realized_cap_bear switching from S2F to realized price floors right when the original model failed is quiet revisionism. the 859K ETF data is the real thesis
PlanB switching from S2F price targets to realized price floors is quiet admission that S2F was wrong. the 859K ETF absorption data is the real thesis here, not the chart model
realized price didnt help anyone when FTX imploded and BTC tagged 15K. floor thesis works until a black swon liquidity event stress tests it. still bullish tho, ETF demand is structural
$45K BTC recovering all ETF selloff losses while planb declares 40K the floor. february 2024 was the last time you could buy below realized price
859K BTC absorbed through ETFs in months and people still doubt the floor thesis. supply shock meets wall street demand, math is simple
realized price floors strengthening at 45301 btc makes the s2f model look solid this cycle
859K BTC through ETFs in months and PlanB’s floor thesis looks better than his S2F model ever did. demand side changed the game
Bohdan M. is right. ETF inflows are the real story, not chart models.
859K BTC absorbed through ETFs in months. The demand side has fundamentally changed since PlanB first wrote S2F.
859K BTC through ETFs in months and PlanB still gets credit for the floor call. ETF demand did the work, not a stock-to-flow chart
the realized price thesis ignores what happens in a forced liquidation cascade. last time BTC was at 15K nobody cared about on-chain cost basis. ETFs absorb until they dont
Soren V. realized price means nothing in a forced liquidation cascade. FTX proved that at 15K when nobody cared about on-chain cost basis
