币界网报道：Coinbase has emerged as the dominant custodian for spot Bitcoin ETFs, securing an 81% market share among the eight newly approved funds, according to data from BitMEX Research. The exchange holds assets for major players like BlackRock's iShares Bitcoin Trust (IBIT) and Grayscale Bitcoin Trust (GBTC), collectively managing over $28 billion in crypto ETF assets. This positions Coinbase as a critical infrastructure provider in the institutional crypto space. Meanwhile, Coinbase Derivatives has expanded its offerings by launching Bitcoin and Ethereum futures contracts, targeting both institutional and retail investors. The new products include micro-sized contracts (1/100th of a Bitcoin and 1/10th of an ETH) alongside standard contracts, providing more accessible entry points for smaller traders. This strategic move comes as Coinbase reports its first profitable quarter in two years, with Q4 2023 net income reaching $273 million—a significant turnaround from its $557 million loss in the same period last year. The exchange attributes this recovery to increased trading volumes (up 64% QoQ to $154 billion) and growing institutional interest in crypto products. Analysts suggest Coinbase's dual focus on custody services and derivatives trading could strengthen its position as a comprehensive crypto platform, particularly as traditional finance firms increasingly enter the digital asset space through ETFs and other regulated products.
