I just looked at Coinbase's asset report, and I was surprised to learn they manage $377 billion in assets. This likely includes funds held by major Bitcoin ETFs. It turns out Coinbase's asset management scale is enormous. Over 99% of their assets are stored in cold wallets, and they protect their funds through decentralized private key management, multi-person approval processes, and anomaly monitoring. As a US-listed company, Coinbase is required to regularly disclose financial statements and undergo audits; their entire asset management system is worth studying. In fact, retail investors can definitely learn from this approach: keep core assets like BTC and ETH for long-term holdings in cold wallets, use a separate wallet for daily transactions, and another separate wallet for Meme, airdrops, and DApp interactions. Never put all your assets in one place, and definitely don't authorize your core asset wallet to various places. The larger your assets, the more you should manage risk like an institution.
