A previously inactive smart-money wallet identified as 0x15a has returned to the market by depositing $1 million in USDC to Hyperliquid and opening a 200 BTC long using 40x leverage. The position carried a notional value of about $12.58 million, showing how a relatively small margin deposit can control a much larger perpetual futures exposure. Onchain Lens said the address had not traded since March this year, and data shows its cumulative profit in perpetual futures (crypto derivatives without expiry) is დაახლოებით $2.28 million.
