Bill Miller’s Flagship Fund Discloses $44.7M Stake in Grayscale Bitcoin Trust
The Miller Opportunity Trust has made its first investment in bitcoin after first indicating it could do so back in February.

Miller Opportunity Trust, the flagship fund offered by noted hedge fund manager and bitcoin bull Bill Miller, disclosed in an Aug. 27 SEC filing a $44.7 million stake in the Grayscale Bitcoin Investment Trust (GBTC).
- The fund, which had assets of $3.1 billion as of June 30, said it owned 1.5 million shares of GBTC. (Grayscale is owned by Digital Currency Group, the parent company of CoinDesk.) Those shares had a value of $44.7 million as of the end of the June.
- The fund had said in February that it could purchase shares of GBTC up to an exposure limit of 15% of its total assets to bitcoin.
- In Miller’s commentary about the purchase that accompanied the SEC filing, he wrote that “we believe Bitcoin has significant upside potential as a form of ‘digital gold.’ With gold’s market capitalization greater than $11T, Bitcoin’s current cap close to $600B would have a long way to go to catch up.”
- Miller added that “we are early in a continuing adoption curve and Bitcoin will be volatile but we think the risk-reward is attractive.”
- Miller has argued in the past that bitcoin has many advantages over gold as a hedge against inflation.
UPDATE (Sept. 3, 19:35 UTC): Updated to include Miller’s commentary about its investmentin the third and fourth bullet points.

KuCoin Hits Record Market Share as 2025 Volumes Outpace Crypto Market

KuCoin captured a record share of centralised exchange volume in 2025, with more than $1.25tn traded as its volumes grew faster than the wider crypto market.
What to know:
- KuCoin recorded over $1.25 trillion in total trading volume in 2025, equivalent to an average of roughly $114 billion per month, marking its strongest year on record.
- This performance translated into an all-time high share of centralised exchange volume, as KuCoin’s activity expanded faster than aggregate CEX volumes, which slowed during periods of lower market volatility.
- Spot and derivatives volumes were evenly split, each exceeding $500 billion for the year, signalling broad-based usage rather than reliance on a single product line.
- Altcoins accounted for the majority of trading activity, reinforcing KuCoin’s role as a primary liquidity venue beyond BTC and ETH at a time when majors saw more muted turnover.
- Even as overall crypto volumes softened mid-year, KuCoin maintained elevated baseline activity, indicating structurally higher user engagement rather than short-lived volume spikes.
