ETH high win rate band giant whale deposits 18.04 million USDC as margin to Hyperliquid, no further action taken yet

According to on chain analyst @ ai_9684xtpa monitoring, "ETH high win rate band giant whale" directly deposited 18.04 million USDC margin to Hyperliquid using the account 0x655... 1e0B8 5 hours ago, and there have been no further operations at present. I checked and found out that this account has been playing on chain contracts since the previous day. In the past two days, I have tried multiple orders on ONDO and lost $12000.
