how to read this
One wallet drives this market: 0x212f…7fd2 accounts for 68% of all whale buy volume ($155K). 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 3 cents toward 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.
