BlackRock's IBIT spot Bitcoin ETF has reduced its minimum conversion amount by 96%, now capable of processing transactions as small as $50 million

BlackRock reduced the minimum amount for direct Bitcoin conversion into its iShares Bitcoin Trust (IBIT) from $25 million to $1 million, a 96% decrease. According to BlackRock, this program has processed over $5 billion to date. Bitwise also lowered the minimum amount for its similar service from $100 million to $30 million, a 97% reduction. This expansion allows access to services previously only available to large institutions, now extending to wealthy individual clients and family offices. The "in-kind creation" process involves a Bitcoin holder depositing coins into a trust account through an authorized participant, and the trust issues ETF shares upon settlement. The traditional method of selling Bitcoin for dollars and then repurchasing the ETF involves transaction costs and potential tax implications, while in-kind creation streamlines this process into a single transaction. However, the tax implications vary depending on the holder's individual circumstances and legal structure, requiring separate tax advice. The SEC officially approved in-kind creation and redemption for cryptocurrency ETFs in July 2025. In June, Morgan Stanley and Galaxy announced a program that reduced the minimum amount from $25 million to $5 million and could shorten the onboarding period by up to 75%. As of June, in-kind creation accounted for 62% of total Bitcoin allocations, a significant increase from 28% in March. During the three months leading up to July, the average completed transaction size for 21Shares was approximately $5 million. As of August 25th, the total holdings of the 13 U.S. spot Bitcoin ETFs were 1,246,336 BTC, representing 5.935% of the total Bitcoin supply of 21 million. IBIT alone holds 765,389.9 BTC, with assets under management of $60.65 billion. BlackRock's head of digital assets, Rob Mitchnik, stated that incidents such as kidnapping, ransom demands, and storage failures can motivate holders to move their assets into ETFs. Chainalysis reported 46 violent cryptocurrency incidents by the first half of 2026, with an estimated $30 million in assets stolen by attackers. This is more than half of the annual record of $58 million in 2025. CertiK reported 52 verified incidents in the first half of the year, a 33.3% increase year-over-year, with a total exposure of $124.1 million, noting a sharp increase in home invasion incidents from 1 to 20. However, the shift of self-custodied Bitcoin to ETFs also highlights a structural issue where coins become concentrated in a few institutions. According to CryptoSlate's analysis, Coinbase is involved as a custodian or major custodian for approximately 80.8% to 84.1% of U.S. Bitcoin ETF assets. BlackRock's documents list Anchorage as an additional custodian, while ARK uses Coinbase, BitGo, and Anchorage, Fidelity uses its own digital asset subsidiary, and VanEck uses Gemini. From August 17th to 25th, the seven trading days saw a net inflow of $2.57 billion into U.S. spot Bitcoin ETFs, with IBIT accounting for $1.82 billion (71%).
