According to Onchain Lens, the deposit on May 16 was used to increase an existing leveraged Ethereum position on Hyperliquid (crypto derivatives trading platform).
Machi Big Brother deposited 250,000 USDC into Hyperliquid (crypto derivatives trading platform) on May 16 to increase his 25x leveraged Ethereum long, according to Onchain Lens. The transaction points to a higher-conviction directional bet on Ethereum using leverage (borrowed exposure to amplify gains or losses), which can magnify both potential returns and liquidation risk.
