Binance SAFU Fund Buys 15K BTC, 21.5% Return

The signal here is less about the size of the purchase than about what an exchange chooses to hold in its emergency reserve. Allocating a user-protection fund to a volatile asset deepens the link between the exchange's balance sheet and crypto-market swings, which cuts both ways: it can grow the buffer in strong markets, but it also means the reserve is marked to the same cycle it may be called on to cushion. Whether other exchanges follow with similar reserve allocations is the open question.
