❓ Frequently Asked Questions

Can you make money on Polymarket without crypto trading?
Yes. Polymarket offers prediction markets across politics, sports, entertainment, crypto, and more. Fengdubiying proved that specializing in esports — specifically League of Legends — can generate millions in profit. The key is deep domain expertise: understanding team dynamics, player form, meta shifts, and historical patterns better than the general market. Any niche where you have informational edge is profitable.
What is domain expert trading on prediction markets?
Domain expert trading means focusing on categories where you have superior knowledge compared to the average market participant. Instead of competing with algorithmic bots on speed, you compete on information quality. A LoL esports expert who tracks team scrimmages, roster changes, and patch impacts can estimate match probabilities more accurately than the crowd — creating consistent edge.
How do you find mispriced markets on Polymarket?
Look for markets where: (1) your estimated probability differs from the market price by 10%+, (2) you have specific information the crowd is likely missing, (3) the market has enough liquidity to enter and exit positions, and (4) resolution is clear and verifiable. Track your predictions over time — if your accuracy consistently beats the market, you have genuine edge worth sizing up.
What position sizing strategy works best for Polymarket niche markets?
Kelly Criterion scaled to 25-50% is standard for high-conviction niche trades. With a genuine 10-point edge (your estimate: 70%, market: 60%), Kelly suggests ~25% of bankroll per trade. Use fractional Kelly to survive variance. Key rule: only size up on markets where your knowledge advantage is highest. Skip marginal opportunities and wait for high-conviction setups — quality over quantity.
How do you build edge in Polymarket prediction markets?
Three approaches: (1) Information edge — access data or analysis others miss (proprietary models, niche community knowledge, real-time event monitoring), (2) Speed edge — react to breaking news faster than the crowd updates the market, (3) Analytical edge — better probability calibration through systematic tracking and model building. The best traders combine multiple edges in their specialty domain.
