According to Lookonchain monitoring, a whale (0x5F64) deposited 8.39 million USDC into Lighter to go long on ARC, establishing a long position of 210 million ARC tokens (US$20.45 million), pushing the price up to US$0.15, attempting to attack the Lighter protocol by going long on ARC tokens. Subsequently, the price of ARC fell, the long position was liquidated, and the whale withdrew the remaining 3.06 million USDC from Lighter, incurring a loss of US$5.3 million. Two months ago, another whale bought 16.2 million ARC tokens (US$573,000) and used a DCA strategy to sell 9.8 million ARC tokens (US$0.115/coin, US$1.13 million), holding the remaining 6.4 million ARC tokens (US$303,000), making a profit of US$861,000.
