Market maker. 72% of its fills rest on the book, 411 times a day. It earns the spread and the maker rebates; a copier who takes liquidity pays that spread instead.

Speed trader. 100% of its fills are in 5- and 15-minute crypto windows, where the edge lasts seconds — gone by the time a copy lands.

One big win. 56% of its all-time profit came from a single market — “Bitcoin Up or Down - October 4, 9:05PM-9:10PM ET”. That is one call that paid, not a record to follow.

Copy check: what a follower would have made

We only replay wallets that pass the structural checks above — this one fails on “market maker”, so a copy would be off before the first fill. See the wallets that pass.
