Bitcoin first crossed $100,000 in late 2024. For some, it was the inevitable conclusion of a decade-long thesis. For others, it seemed sudden. In reality, it was the product of several overlapping structural forces that had been building for years. Understanding what drove it matters, because those same forces continue to shape where Bitcoin goes from here.
This is not a price prediction. It’s an attempt to identify the underlying dynamics with some analytical rigour.
The ETF effect
The single biggest structural change in Bitcoin markets in recent years was the January 2024 approval of spot Bitcoin ETFs by the US Securities and Exchange Commission.
Prior to ETFs, most institutional capital that wanted Bitcoin exposure was either buying through futures, using custodians with significant operational friction, or simply sitting it out. The ETF wrapper changed the calculus. It allowed pension funds, family offices, registered investment advisors, and retail brokerage users to buy Bitcoin through familiar channels with familiar custody arrangements.
The inflows were substantial. In the first year alone, spot Bitcoin ETFs - particularly BlackRock’s IBIT - accumulated positions that ranked them among the largest Bitcoin holders in the world. The persistent bid from ETF inflows created structural buying pressure that distinguishes this cycle from previous ones.
ETF buyers are also less likely than retail speculators to sell during corrections. The diversified portfolio buyer rebalancing annually looks very different from the 2017 retail participant who bought on FOMO and sold at the first sign of a downturn.
The halving cycle
Bitcoin’s supply schedule is built into its protocol. Every roughly four years, the reward paid to miners for adding a new block is cut in half. This “halving” reduces the rate of new Bitcoin issuance.
The April 2024 halving reduced the block reward from 6.25 BTC to 3.125 BTC. Historical patterns suggest Bitcoin tends to make significant price moves in the 12-18 months following a halving, though the mechanism is debated. The direct supply reduction is modest - what matters more is likely the psychological signal and the effect on miner selling pressure.
In each of the three previous halving cycles, Bitcoin reached new all-time highs in the following year. The 2024-2025 cycle continued that pattern.
Whether halvings will continue to produce the same pattern is genuinely uncertain. As block rewards decrease and transaction fees become a larger portion of miner revenue, the dynamics will shift. The next halving is approximately four years away.
Institutional adoption as infrastructure
Beyond ETFs, the infrastructure of institutional Bitcoin participation has matured significantly. Major banks now offer Bitcoin custody services. The Chicago Mercantile Exchange’s Bitcoin futures market is deeply liquid. Corporate treasury allocations - started conspicuously by MicroStrategy and now followed by others - have normalised the idea of Bitcoin on a corporate balance sheet.
This institutional infrastructure changes Bitcoin’s volatility profile gradually, not immediately. More long-term holders with diversified motivations produce a different market structure than one dominated by short-term retail speculation.
Where the data suggests we are in the cycle
Several on-chain metrics are used by analysts to assess where Bitcoin sits within its market cycle. None of them are reliable in a predictive sense, but they’re useful for understanding the present.
MVRV ratio (Market Value to Realised Value) compares Bitcoin’s current market cap to the aggregate cost basis of all coins. Historically, extreme highs in this ratio have coincided with cycle tops, and extreme lows with bottoms. As of early 2026, the ratio is elevated compared to the mid-cycle average but below the levels seen at the peaks of previous cycles.
Long-term holder behaviour: the proportion of Bitcoin that hasn’t moved in over a year remains historically high. Long-term holders distributing aggressively has historically been a late-cycle signal. That distribution has been occurring but at a measured pace.
Exchange balances: the amount of Bitcoin held on exchanges - liquid and available to sell - continues its multi-year decline as more holders move to self-custody. Reduced exchange supply is generally interpreted as a reduced immediate sell-side.
None of this constitutes a reliable map of the future. Bitcoin has confounded cycle analysis before. The ETF-driven structural change in the buyer base may compress the volatility profile compared to previous cycles, making direct comparisons unreliable.
The questions that matter now
The relevant questions for understanding Bitcoin’s next phase are structural, not speculative.
How much institutional allocation runway remains? Most large pension funds and sovereign wealth funds have minimal Bitcoin exposure. If even a fraction of global institutional capital follows the early movers, the size of that incremental demand relative to supply is significant.
What happens to miner economics post-halving? Lower block rewards require either higher prices or more efficient operations to sustain the security budget. This is a long-term structural question, not an immediate concern.
How does regulation develop? The US has moved toward a more permissive regulatory stance. Jurisdictions with large institutional asset pools - the EU, parts of Asia - are at various stages of framework development.
Bitcoin crossed $100K through a combination of structural demand changes, supply dynamics, and improved institutional access. The forces that drove it there haven’t reversed. But they’ve also been substantially priced in by markets that anticipated them.
