Brazil’s Itau Unibanco, the largest bank in the country, has launched a cryptocurrency trading service, allowing clients to trade Bitcoin and Ether through its investment platform. The bank, a major player in Latin America, also plans to expand its offerings to include more cryptocurrencies. Itau will act as the custodian, storing crypto assets for clients, though initially, external crypto wallets cannot be used for deposits and withdrawals. This move aligns with Itau’s earlier launch of digital asset custody and comes amidst preparations by Brazil’s leading banks for the Drex, the digital Brazilian real.
