Bitcoin exchange reserves hit 5-year low as BlackRock’s IBIT soaks up far more than miners
Bitcoin exchange reserves have fallen to 2.3 million BTC, the lowest since 2018, tightening spot liquidity. BlackRock’s spot Bitcoin ETF, IBIT, is reportedly absorbing about 2,100 BTC per day, versus daily mining output of roughly 234 BTC—around 9x more than new supply.
The article links this to a structural demand shift: over the past 15 months, ETFs and firms such as MicroStrategy are said to have removed about 1.76 million BTC from exchanges, reducing liquid sell pressure. With redemption mechanics viewed as “orderly,” traders appear less inclined to bet on a sharp BTC dip.
The market backdrop includes an “April resolution” window with six days left, while traders price in a potential supply squeeze rather than a retail-driven move. Ethereum-related markets are described as unchanged.
What to watch is near-term catalyst risk: trading volume in Bitcoin-linked markets is thin, suggesting participants are waiting. Any BlackRock or MicroStrategy flow updates could quickly move sentiment before April 30.
Bullish
这则消息偏利多，核心在于“交易所可售BTC变少 + ETF持续净吸收”。当BTC交易所储备跌至2018年以来低位时，现货市场的即时抛压通常会下降；同时若IBIT日买入量显著高于新增矿工供给（文中约9倍），会在短期内强化供需错配，给BTC价格提供上行支撑。
与过往周期对比：在ETF或机构持续净流入、且交易所库存持续走低的阶段，市场往往更容易出现“跌不动”（现货缺货导致反弹更快）的走势；反之，在交易所库存上升、机构净流出时，市场更容易因可售筹码增加而承压。
短期层面，文章指出比特币相关市场的成交偏薄，说明多数资金在等待催化剂。若在4月30日前出现更多ETF/公司流入数据，可能触发情绪与仓位的快速再定价；反之如果出现流入显著放缓，也可能引发波动。
长期层面，若这种交易所流出与ETF需求的结构性关系延续，BTC的“可交易供给”会持续受限，从而让下行风险相对更难兑现，支撑更偏向趋势延续。但需要注意：ETF需求并非线性，仍可能受宏观流动性、利率预期与风险偏好影响，因此价格反应可能呈现阶段性而非单向。
