The best traders this month on Hyperliquid mainnet's public leaderboard (testnet has none: a copy here mirrors their mainnet positions into your testnet account)
Paid signals
Leaders who publish their trades as signals: buy early access in USDC to read them first and copy them. Positions on chain stay public; what is private is the signal and its timing.
