Could anyone get out?

A launch that only ever gets bought is not a market. Because the cohort sweep reads every swap, each trade can be split into a buy or a sell, and each coin's true peak-to-last drawdown measured since launch rather than over a recent window.

What survived

Of everything in the scan window, — pools traded in the last 30 min. These are the ones still moving, ranked by how far they are above the price they launched at. A coin needs at least 5 trades in that window to appear here — one swap makes a pool look immortal and unmoved at the same time. This is the top 25 by multiple, and "up from launch" is a weak measure of success for the reason given in the method: a V3 launch can barely go down. Read it as the tail, not a scoreboard.
