Bitcoin Exchange Reserves Fall to a 5-Year Low as BlackRock's IBIT Buys 9x Daily Mining Supply

Bitcoin held on exchanges has dropped to about 2.3 million BTC, the lowest level since 2018, tightening the pool of coins readily available for spot selling. At the same time, BlackRock's iShares Bitcoin Trust (IBIT) is absorbing roughly 2,100 BTC per day, far above estimated daily mining output of about 234 BTC. That supply backdrop is shaping positioning in the April 30 "Bitcoin dips to $60,000" market, which has six days left to settle. Despite active trading, participants are largely fading the odds of a sharp move down to $60,000, arguing that constrained exchange supply and steady ETF demand reduce the appeal of bearish bets. Over the past 15 months, ETFs and corporate buyers such as MicroStrategy have removed an estimated 1.76 million BTC from exchanges, shrinking liquid supply. With more bitcoin locked inside ETF wrappers that feature orderly creation and redemption processes, traders are treating a $60,000 print as less probable, and pricing in a potential supply squeeze tied to IBIT's daily absorption pace. Ethereum-related markets are described as unchanged and not impacted by these bitcoin-specific dynamics. Why it matters: This shift in where bitcoin is held differs from typical market-cycle dynamics. Exchange balances sitting at 2018-era lows leave fewer coins available for immediate selling, while IBIT alone is buying roughly nine times daily mining output. The combination of reduced on-exchange supply and persistent ETF demand can create upward price pressure that is less dependent on retail sentiment or speculative momentum. What to watch: Trading in these bitcoin-linked markets has been thin, suggesting many participants are waiting for a catalyst. With the April 30 resolution approaching, any updates from BlackRock or MicroStrategy on inflows or outflows could move pricing quickly. A "YES" share on bitcoin dipping to $60,000 by April 30 would pay $1 if bought below 30¢, but the trade requires a sharp reversal within a week. With ETF-driven demand dominating the narrative, betting on a contrarian dip is difficult to justify absent a clear negative catalyst.
