Holders call the coins they're early on. Each call is stamped with the market cap at that moment, so the multiple since then is public and can't be edited.
Ranked by the median multiple of their calls in the last 30 days, with at least 3 calls. The median means one lucky call can't top the board.
Callers need at least 3 calls in the last 30 days to be ranked. Make calls on coins you hold from their coin pages.
