Trader overview
0x4ef0194e8cfd5617972665826f402836ac5f15a0 turned $621 into $40,368 in realized PnL — that's a 6,237% ROI across 10 perfect trades. Zero losses. This isn't a bot running 10,000 micro-bets; this is a sniper who only pulls the trigger when the edge is unbearable.
Meet costunan, ranked #4,220 on the Polymarket leaderboard — but don't let the rank fool you. This is a whale who moves quietly, trades in bulk across 9,071 markets, and has a 100% win rate across exactly 10 closed positions. Average trade size? $10.44. Average entry price? $0.64. He's not chasing glory; he's compounding noise into alpha.
Strategy: He plays binary outcomes on high-volume, short-duration Bitcoin hourly events. Think Bitcoin Up or Down - September 5, 3AM ET (+$2,974) and Bitcoin Up or Down - September 3, 1AM ET (+$1,273). He scalps small edges in liquid markets where retail panic-pukes misprice probabilities. The edge hack? He buys when the crowd overcorrects to a headline, then exits into the snapback.
Proof: 10 trades, 10 wins. Max single win: $2,974. Max single loss: $0. His buy/sell ratio of 0.85 suggests he's more often selling into rallies than buying dips — classic contrarian flow. Total deposits were just $621; he's withdrawn $39,354. The wallet is nearly empty now — he locked profit and ran.
Edge: Most degens chase 10x moons on obscure event contracts. Costunan's edge is temporal efficiency — he only enters when the event resolves within hours, not days. No overnight risk, no narrative decay. It's math over gut, execution over ego.
Now: Zero open positions, zero portfolio value. The wallet is a tombstone of perfect asymmetry. But that doesn't mean he's gone — he could be farming the next batch of hourly BTC contracts tomorrow. The realism caveat: 10 trades is a small sample. Survivorship bias is real. You don't see the wallets that blew up on trade #11.
