Wallet full, portfolio empty: this trader made $150M in volume with a 97.8% win rate and still sits at -$1.2M lifetime PnL. 0xb7511d7b0dcb75ffad0507cbac7223653d08915 is a whale with the math and the medal — rank 2,154,465, active across 15,117 markets, mostly NBA spreads. Strategy is pure volume grinding. Average bet $117. Median entry 56 cents. Buy-sell ratio of 500 to 1 tells the real story: they're a directional accumulator, not a hedger. 193 open positions right now. They swing for the fences on low-probability outcomes and hit often. The numbers bend in their favor on paper. 97.82% accuracy is unnatural for any retail trader — suggests either extreme selection bias (only counting completed trades, ignoring dust positions) or a tight, repeatable process. Best single win was Spread: Lakers (-7.5) for $96,886. Worst loss only -$4,837. That's a 20:1 asymmetry most traders dream about. But here's the trap: $150.6M traded, 97.8% accuracy, and still drowning $1.2M. Either the wins are small and frequent while the losses are fewer but fatal, or they're catching the tail end of collapses after sizing down. Portfolio sitting at $62,852 suggests they've been clawing back from worse. Current 193 open positions across NBA markets is a live bet that volume and accuracy eventually converge to positive returns. Risk level: medium. Should probably be higher given the concentration.
