Just saw that Block released their proof of reserves and the numbers are pretty substantial. Jack Dorsey's payment company is holding 28,355 BTC in total, valued around $2.2 billion at current prices. What's interesting is how it breaks down - about 19,357 BTC is client assets they're custodying (roughly $1.5 billion), while the company keeps 8,997 BTC on its own balance sheet (close to $700 million). This kind of transparency on reserves is becoming more common, and it shows Block Inc has serious Bitcoin exposure across both their client operations and treasury. The fact that they're willing to publicly verify these holdings says something about where the company is positioning itself in crypto.
