Bitcoin Halving Countdown: Miner Selling Pressure vs. ETF Inflows – A Battle for Price Direction

Halving Countdown: Two Sides of the Supply-Demand Scale

With Bitcoin's fourth halving event entering its final countdown, the market stands at a delicate supply-demand juncture. The halving will reduce block rewards from 6.25 BTC to 3.125 BTC, slashing daily new supply from roughly 900 BTC to 450 BTC. Meanwhile, sustained inflows into spot ETFs are absorbing significant selling pressure on the demand side, setting the stage for a strategic battle between existing and incremental capital.

Miner Reserves: From Accumulation to Cautious Distribution

On-chain data reveals a gradual decline in Bitcoin reserves held in miner wallets over the past few months. According to CryptoQuant, miner holdings have retreated from their early-year highs, with some large mining firms choosing to lock in profits ahead of the halving to prepare for rising hash cost and the revenue impact of reduced rewards. This "preemptive selling" is not panic-driven liquidation but a rational assessment of post-halving profitability—older mining rigs will be phased out, and capital expenditures need to be secured in advance.

However, the absolute scale of selling pressure remains limited. Glassnode data shows that miners' daily outflows account for only a tiny fraction of total market volume, and recent "sell signal" transfers to exchanges have not surged. More miners are opting for over-the-counter deals or DeFi lending to obtain liquidity rather than directly dumping on exchanges.

ETF Inflows: Institutional Buying as a Counterweight

In stark contrast to miners' caution, spot Bitcoin ETFs have consistently attracted net inflows since their launch. According to SoSoValue, cumulative net inflows into U.S. spot Bitcoin ETFs have surpassed several billion dollars as of the latest week, with top products frequently recording single-day inflows exceeding hundreds of millions. This sustained buying not only absorbs miners' natural selling but also shifts marginal pricing power in the market.

Notably, the pace of ETF inflows is highly correlated with Bitcoin's price. When prices pull back to key support levels, ETFs often see a surge in subscriptions, creating a "dip-buying-rebound" cycle. This mechanism provides an additional cushion ahead of the halving, reducing the likelihood of a deep correction.

The Battle: Short-Term Volatility vs. Medium-Term Trend

In the short term, market volatility around the halving may intensify. Historical patterns suggest that halving events often trigger a "sell-the-news" correction, but the magnitude and duration depend on prevailing macro liquidity and market sentiment. Currently, the tug-of-war between miner selling and ETF inflows is in dynamic equilibrium: if ETF inflows slow, miner selling could briefly dominate price action; conversely, if institutional buying accelerates, the positive supply shock of the halving may be priced in earlier.

Over the medium term, the supply impact of the halving is structural. Even if miners increase selling ahead of the event, the total amount cannot compete with daily incremental demand. According to Bloomberg Intelligence estimates, current daily ETF purchases already exceed several times the post-halving daily miner production. This implies that, barring a severe macro deterioration, Bitcoin's supply-demand gap will widen progressively, laying the foundation for a higher price center.

On-Chain Signals and Market Sentiment

On-chain metrics show that the supply held by long-term holders (LTH) continues to hit new highs, indicating that a large portion of circulating coins is being locked up, further contracting the available trading supply. Meanwhile, Bitcoin balances on exchanges have fallen to multi-year lows, reflecting a trend of investors moving assets to self-custody or ETF custodians. These signals all point to a "supply squeeze" scenario, resonating with the halving's supply reduction.

On the sentiment front, market expectations for the halving are partially priced in but not fully digested. According to Alternative.me, the Crypto Fear & Greed Index remains in the "Greed" zone but has not reached extreme levels, suggesting there is still room for upside, while also warranting caution against overheating and subsequent corrections.

Conclusion: Power Shift, But Direction Unchanged

The miner selling pressure and ETF inflows during the Bitcoin halving countdown represent a changing of the guard among market participants. Miners, as the native supply side, are primarily engaged in cyclical financial adjustments; ETFs, representing institutional capital, are the long-term engine of incremental demand. Short-term battles may cause price fluctuations, but in the medium term, the widening gap between supply cuts and demand growth will drive Bitcoin into a new phase of price discovery. Investors should closely monitor the sustainability of ETF inflows and the pace of miner selling to navigate volatility and grasp the trend's pulse.
