The chart lit up again this morning. PlanB, the masked prophet of Stock-to-Flow, dropped another number: $500,000 to $1,000,000 for Bitcoin before this halving cycle ends. The crypto Twitter machine is already spinning — FOMO bots are pumping, bag holders are clutching their screens. But here‘s the thing I’ve learned after eight years of chasing green candles: when the same prediction gets reheated for the third time, it‘s usually cold leftovers, not a fresh feast.
Context: The S2F Saga PlanB isn’t new. He‘s the anonymous Dutch analyst who turned Bitcoin’s scarcity into a cult narrative. His Stock-to-Flow model — mapping the ratio of existing supply to annual new issuance against price — predicted Bitcoin would hit $100,000 by the end of 2021. We all remember how that ended: $46,000 in December, a 54% miss. The model’s power law curve looked sexy on a log chart, but real markets don‘t care about sexy math. They care about liquidity, adoption, and narrative stickiness.
The current halving cycle started on April 19, 2024. We’re now 639 days away from the next halving (projected around early 2028). PlanB‘s latest call sits right in this window. He claims that with reduced block rewards and growing institutional interest, Bitcoin will rocket past half a million. But here’s the catch: the same institutional flow narrative has been running since the ETF approvals in January 2024. Net inflows into US spot Bitcoin ETFs have actually slowed from the initial frenzy — daily averages dropped from $500M in February to under $100M in May. The second derivative of demand is flattening.
Core: The Data Behind the Dream Let‘s dissect the numbers. Bitcoin’s current price hovers around $68,000. To hit $500,000, the total market cap needs to rise from $1.35 trillion to $10 trillion. That‘s a 7.4x multiple. In the last cycle (2020-2021), Bitcoin did about 6x from halving to peak. So a 7x is within historical range, but that cycle had a liquidity tailwind from zero interest rates and massive stimulus checks. Today’s macro environment is different: US 10-year real yields are still positive at 2.1%, the Fed is hawkish, and global liquidity is tightening. The easy money party is over.
From my own data aggregation dashboard, I‘ve been tracking on-chain signals that matter more than any S2F projection. The Long-Term Holder (LTH) spent output profit ratio (SOPR) has been declining since March. That means long-term believers are taking profits, not accumulating. When the smartest money in the room sells into a bullish prediction, I start to wonder who’s buying. The MVRV Z-score, a classic top indicator, is currently at 2.1 — historically, peaks above 3 have preceded major corrections. We‘re not at the froth level yet, but the trend line is pointing up.
PlanB’s model also assumes a linear relationship between scarcity and price, ignoring demand. That‘s like saying gold should be worth $1 million per ounce because it’s scarce. But gold’s price is driven by jewelry, central bank reserves, and inflation hedging. Bitcoin‘s price is driven by narrative, speculation, and network effects. When the narrative fades, the price follows. Look at NFT floors — they’ve collapsed 80% from peak. The hype cycle is shorter now. This prediction might be the last gasp of the 2020-2021 supercycle narrative.
Contrarian: The Unreported Angle What nobody’s talking about is the time decay of this prediction. PlanB posted it on an unknown blockchain news aggregator, not his own verified Twitter account. That’s odd. In 2021, he hyped his calls with daily charts and community engagement. Now it‘s a one-liner buried in a third-party site. That suggests either he’s lost conviction or the market has left him behind. Either way, the signal is weaker.
Another blind spot: the prediction range is massive — $500k to $1M. That‘s a 100% spread. Real analysts give tight bands. This is a fishing net thrown into the ocean, hoping to catch believers who will ignore the spread and just remember the upper number. It’s a marketing move, not a prediction.
And here‘s the kicker: the halving already happened. The supply shock narrative is priced in. Since May 2020 halving, Bitcoin returned 626% over the next 18 months. Since April 2024 halving, we’ve seen only 12% gain in 13 months. The diminishing returns pattern is clear. Each halving gives smaller multiples because the base is larger. At $68,000, a 7x to $500k is a tall order when the market cap is already $1.35T. New money needs to enter at a much faster rate.
Takeaway: Watch the Tide, Not the Song I‘m not saying Bitcoin can’t hit $500k. I‘m saying PlanB’s model alone isn’t enough. The real signals are on-chain: look for a spike in illiquid supply moving to exchanges, or a rise in LTH spending. Those will tell you if the big boys agree. Right now, they‘re selling. The hype cycle is fading. Speed is the only currency that matters here — speed to recognize when a narrative is stale.
In the jungle of alerts, silence is gold. I’ll keep my ears open, but I‘m not buying the same song twice. We rode the wave, now we read the tide.
Post Script Before you ape in with leverage, ask yourself: Am I buying because of a model that failed before? Or because of real adoption, real demand, real on-chain growth? The answer is clearer than any S2F curve.
