On May 19, 2025, Coinbase officially joined the S&P 500, becoming the first major crypto exchange to make it into the index. It felt like a huge moment for the crypto industry—a real sign that it's being taken seriously by the mainstream financial world. The timing couldn’t have been more striking either, with Bitcoin$BTC

crossing the $100,000 mark and altcoins like Ethereum$ETH

, Solana$SOL

, and XRP seeing strong inflows. But it wasn’t all good news—Coinbase also revealed it had been hit by a cyberattack, which raised fresh concerns about data security in the space.
