Just saw the data—bitcoin balance on exchanges just hit an all-time low. Basically, people are pulling their coins off trading platforms and moving them to cold storage or private wallets instead of leaving them sitting there. The usual explanation is the "not your keys, not your coins" mentality finally catching on, plus all those exchange hacks over the years have made people nervous about centralized custody. What's interesting is that with over 20 million BTC already in circulation and more of it locked away in long-term storage, the actual supply available for trading keeps shrinking. If buying pressure stays the same or picks up while fewer coins are available on exchanges, that could create some real price movement. Analysts are calling it bullish, though honestly the relationship between exchange balances and price is messier than people make it sound. Still, it's a signal worth watching—shows that the market structure is shifting toward more self-custody and less reliance on exchanges as storage.
