Lessons from HFTs: Flip Coins

I spent my career at some of the top quant trading firms in the US (e.g. HRT, JS, SIG, IMC, Headlands). Ironically seemed to LOVE variance. We'd bet on random things with no edge: card turns, elevators times, etc.

Also saw retail traders yolo into 0DTEs. Sports bettors pay insane vig.

Currently on my garden leave. Spending some time working on personal projects. One of these is a platform for pure financial variance. No house edge, no rake, no spread, instant settlement.

Messing around with yoss.gg -- peer-to-peer coin flips settled in USDC on Base with no fees. Can play against strangers or friends.

Someone flip with me!
