Beyond trading venue operations, the company has put into practice a considerable balance in an array of counterparties, ranging from peer exchanges and miners to issuers of exchange trade products (ETPs).
Coinbase’s total customer assets are 1,045,246 BTC, and the platform similarly protects Revolut (28,536 BTC), Bitvavo (22,695 BTC), and Newton (1,480 BTC) reserves. Coinbase’s institutional clients sketch vivid portraits of modern Crypto Finance.
Secure this growing safe is BlackRock, whose iShares Bitcoin Trust (IBIT) quickly accumulated 607,086 BTC, achieving the largest ETF position distinction under Coinbase watches. Grayscale’s GBTC has 189,416 BTC, with newcomers in ETFs such as ARK investing in 21 shares, collectively lifting the ETF/ETP segment to more than 1 million BTC.
Coinbase remittances are far beyond the funds traded on exchanges.
