Find traders with real, repeatable skill
One huge ROI can be luck. Polyrank ranks the 2.9M-wallet field by calibration, edge, and risk — so you can follow the genuinely skilled, not the lucky.
ROI = realized profit ÷ gross traded notional on a single resolved position — the denominator is the Notional column (buy cost basis plus sell proceeds), not the cost basis. Profit is gross of fees. Past performance does not predict future results. Not financial advice.
