A trader known as FirstOrder has successfully extracted just under $400,000 from a single Bitcoin trading lane on Polymarket, focusing exclusively on 15-minute Bitcoin up/down markets. Employing a disciplined strategy, FirstOrder capitalizes on price deviations from the spot, entering trades as the market lags and exiting as volatility tightens. This approach has resulted in six consecutive profitable trades. Previously, FirstOrder's wallet showed a total profit and loss (PnL) of approximately $328,000. Recently, an additional $70,000 has been accrued using the same trading structure, bringing the total to nearly $400,000. The active market for these trades was the Bitcoin Up or Down market as of December 28.
