Trader overview
“Mathematically impossible” — 83.6% win rate, 99% of bets above 0.98c, and still down 50% on deposits. Meet BuyOnlyNo, a Polymarket trader who turned $18,227 into a -49.99% ROI with surgical precision. One wallet. Zero exit strategy.
BuyOnlyNo (rank #68,626) — conservative trader, 1,127 total trades, 83.6% win rate across 1,619 markets. Looks like a bot. Could be a bot. The numbers say “prop firm tier” — the PnL says “learning curve.”
Strategy: Buys shares at 0.98–0.99c average entry — basically only trades “almost sure” outcomes. 24-to-1 buy-to-sell ratio. He’s not trading probabilities. He’s farming the last 1–2% of a market’s tail. 34 trades per day. No hesitation.
Proof: Best trade was on Akita Northern Happinets vs. Koshigaya Alphas for +$2,466. Worst trade? Highest temperature in Milan on April 14? for -$350. The Milan loss wiped 8 good wins. That’s the math problem.
Edge: Win rate is elite (83.6%) but he buys at 0.99 — every loss hits 100x harder. On Polymarket, 83.6% win rate with sub-1c average margin means 1 bad day = 10 good days erased. This isn’t edge. It’s survival math the market hasn’t punished ruthlessly yet. His max single loss was $350 — but his average win is under $100.
Now: 98 open positions. Portfolio at $3,052. Net transfers -$12,164. Still depositing. Still buying near certainty. Still waiting for the law of large numbers to bite. If he tightens to 0.995c entry, the edge flips. If he doesn’t, the pattern is “win every day until the day you don’t.”
