The fixed stake

The bot buys with the same amount nearly every time: 0.070 ETH, on 578 of 1,598 positions (36%).

Why fixed

Any single launch is close to a coin flip with a heavy left tail. Sizing up on a launch that "looks good" would mean betting on a judgement the bot does not have. A constant stake turns thousands of near-random outcomes into a distribution, which is the only thing here that can be relied on.

It also makes the book readable. Because every parcel on the field map is the same size, the picture shows outcome and nothing else — no position is visually louder because more money went into it.

Why it cannot simply grow

The stake is small relative to the pools it buys into, and that is not a detail — it is the mechanism. At 0.070 ETH the bot takes about 3% of a median pool. Multiply the capital and the size stops fitting.

This is important enough to have its own page.

The exceptions

The remaining positions use other sizes, mostly smaller. They come from manual activity on the same address and from trades settled in a quote other than ETH — see accounting for how those are kept apart.
