how to read this
One wallet drives this market: 0x9d36…0e68 accounts for 76% of all whale buy volume ($341K). That makes this one desk's position rather than a crowd view — the concentration is the story, and it means a single actor's change of mind would move the whole picture.
Between those entries and the last print the market moved 53 cents against the side whales bought. That is the distance between two observed prices, not a profit: we do not know which of these wallets are still holding.
