The oldest cohort of Bitcoin holders—those who accumulated before the 2017 bull run—are selling at their slowest pace in nearly two years. On-chain data cited by Cointelegraph shows this spending drop to a 19-month low, a shift that typically signals either exhaustion of selling pressure or a retreat into conviction during weak price action.

The timing overlaps with renewed interest in halving-based market models. Analysts tracking the network's four-year cycle point to September as a potential bottom, extrapolating from Bitcoin's historical price troughs relative to the 2024 halving event. The logic rests on the idea that price capitulation clusters around predictable epochs in the block-subsidy calendar.

The practical read: old holders refusing to dump suggests either they've already liquidated through bull runs or they're treating current prices as a floor. Either way, the absence of forced selling from the longest-tenured addresses removes a source of downward pressure. Bitcoin traded near $61,200 at publication, holding above the lows printed in late 2023.

Halving models come with real caveats. They assume past cycle length repeats with rough regularity, and they ignore regime shifts—regulatory snapshots, macroeconomic shocks, or shifts in network utility. September is a calendar guess, not a physics law. Still, the correlation between these models and actual market troughs has held across multiple cycles, making them a reference point rather than a prediction.

What matters operationally is that miner behavior and network growth are decoupled from price cycles. If early holders are indeed holding through weakness, the network's hashrate and transaction throughput should tell whether they're sitting on conviction or just underwater. That separation between conviction and price is the real test.
