yeeyee11 (0xd915db7b0c05cb5649dc84ec06264bc118d01d54) turned $63K into $114K on Polymarket with a 66% win rate — then immediately pulled $79K out, which is the most un-degen move in prediction markets. Rank 2030. Conservative trader. 71 total trades across 67 markets, mostly sports betting with occasional noise plays. Trades slow — 0.2 per day — which tells you this Polymarket trader actually thinks between bets instead of doom-scrolling into ruin. The type who closes winners early and cuts losers clean. The edge is brutally simple: discipline. Average trade size $1,437 on a $63K stack means yeeyee11 never went full degen on a single conviction. Win rate sits at 66.66% which isn't flashy but it's real — top Polymarket traders hovering at 55-60% look sloppy by comparison. Best single trade pulled $12.3K profit off Bucks vs. Pelicans (2026-02-21). Worst trade only bled $8K on Knicks vs. 76ers (2026-02-12). That max loss-to-max win ratio screams position sizing discipline — most Polymarket whales blow $30K trying to revenge trade one bad call. ROI of 68.53% is insane but here's the contrarian angle: yeeyee11 already took the chips off the table. Net transfers show negative $15.7K — meaning they extracted $79K while only depositing $63K total. This is a Polymarket trader who doesn't confuse paper profit with actual money. Low risk classification, 6 open positions instead of 50, portfolio value $27.8K. They're rotating into real life while most prediction market addicts are chasing the next pump. Sports betting focus across 67 markets suggests niche mastery over noise collection. Buy-sell ratio of 6.66 means they're mostly riding winners (buying high conviction, selling into strength) rather than panic liquidating. Current risk level stays low. Only real concern: $27.8K portfolio left on table suggests conviction peaked — they found their edge, cashed out, and moved on. Not everyone with $51K PnL on Polymarket has the mental discipline to actually keep that money.
