An example in numbers
$100 into a pool with $10,000 of liquidity loses about 2% on the way in: 100 / (5,000 + 100). About the same again on the way out, plus swap fees. The coin has to rise about 4% just to break even.
Why it matters
A coin can go up and still lose you money after costs. Larger trades in thin pools lose more.
What Neurolith checks
Every call counts exit loss in and out plus fees for a $100 trade, or the amount you type. A Buy only shows when the odds beat those costs. For holders, the call shows what selling all of it costs now.
A real example
BRETT on Base, checked on 8 October 2026, with $2.5M of liquidity: about 0.01% lost on $100, 0.08% on $1,000 and 0.79% on $10,000.
