Copy trading facts from Copy Trading Index (October 2026), last verified 2026-10-27. Web page: https://copytradingindex.com/platforms/katoshi/. Facts change often: check the platform's own terms before you use it. Not financial advice.

Katoshi is a trading automation platform for Hyperliquid with copy trading through Trading Groups. Members' bots follow every signal of the group owner's bot, on their own Hyperliquid accounts. You pay a builder fee on perps from 0.060% down to 0.010%, by 30-day volume. Group owners receive the fees their members pay.

**What stands out:** A public group owner receives 100% of the platform trading fee that members pay, through Hyperliquid builder codes. Members pay nothing extra.
