Historical 4-Year Halving Cycle Epoch Comparison

Why $100,000 is mostly a supply story

Bitcoin first traded above $100,000 on 5 December 2024, and the round number has acted as a psychological pivot ever since. What made the move possible was a collision of two scheduled events. In January 2024 US regulators approved spot bitcoin ETFs, giving pension funds, advisers and brokerage customers a regulated way to buy. Three months later, the April 2024 halving cut the reward for mining a block from 6.25 to 3.125 BTC, which reduced new supply to roughly 450 coins a day.

That second number is the anchor of this page. At $100,000 per coin, miners produce about $45 million of new bitcoin a day. On days when ETFs take in more than that, the extra demand cannot be met by fresh issuance and has to be filled by existing holders selling, often from coins sitting on exchanges. On days of net outflows, the pressure runs the other way. Watching daily flows against that $45 million line is a simple way to judge whether institutional demand is tight or loose.

Fund choice also matters to long-term holders. BlackRock's IBIT gathered the largest share of assets, while Grayscale's GBTC, which converted from an older trust, still charges a far higher fee than most rivals. Over a decade, a difference of a percentage point a year compounds into a meaningful share of returns, so compare expense ratios before comparing headlines.

To follow this yourself, three public series are enough: daily net flows that each ETF issuer publishes after the US market close, exchange reserve estimates from on-chain data providers, and miner wallet balances, which show whether miners are holding or selling their new coins. When flows stay above the issuance line for weeks while reserves fall, supply is tightening; when flows turn negative and miners sell, the same mechanism works in reverse.

How to read the absorption simulator

The simulator takes three inputs: average daily net inflow in dollars, the bitcoin price you want to test, and a holding period in months. It subtracts the dollar value of the 450 newly mined coins from the inflow and divides what is left by the price. The result is the number of coins that would have to come out of existing supply each day, which it then adds up over the period and compares with the exchange reserve figure in the KPI cards.

Try the defaults first: $450 million a day at $100,000 means demand of 4,500 coins against 450 mined, so about 4,050 coins a day must come from existing holders. Then lower the inflow to $45 million and the absorption falls to zero, because issuance covers demand. Raising the test price has the opposite effect of what many expect: each dollar of inflow buys fewer coins, so a higher price slows the drain on reserves.

Keep the limits in mind. Not every coin bought by a fund comes from an exchange; large blocks trade over the counter. Exchange reserve estimates differ between data providers. Flows reverse quickly in risk-off markets, and the model treats any negative imbalance as zero rather than as coins flowing back. Past halving cycles in the table below peaked 12 to 18 months after each halving, but four data points are not a law, and a larger, more institutional market may behave differently. Use the tool to understand the mechanism, not to time a top.
