ARC experienced a "flash crash" last night and this morning, with a whale address starting to continuously sell off yesterday.

**Feb 26: Whale’s ARC Long Attack on Lighter Fails, Loses $5.3M** Per LookOnChain monitoring, whale address 0x5F64 attempted a long-position attack on ARC via Lighter but failed—its position was liquidated, resulting in a $5.3 million loss. The whale deposited 8.39 million USDC into Lighter to open a 210 million ARC long position (≈$20.45 million), pushing ARC’s price up to $0.15. Separately, another whale bought 16.2 million ARC for $573,000 two months ago. During the recent surge, it used dollar-cost averaging (DCA) to sell in batches: 9.8 million ARC at $0.115, cashing out $1.13 million. The address still holds 6.4 million ARC (≈$303,000) and has locked in $861,000 in profits. Subsequently, ARC’s price plummeted. 0x5F64’s 210 million ARC long position was liquidated, and the whale withdrew the remaining 3.06 million USDC from Lighter. The attack failed, leaving a final loss of $5.3 million.

On Feb 26, Coinglass data shows Coinbase’s Bitcoin Premium Index flipped positive yesterday (Feb 25) at 0.0159%—ending a 40-day streak of discounts—before turning negative again today, though the gap has narrowed to -0.0033%. This signals warming buying sentiment in the U.S. market. BlockBeats Note: The Coinbase Bitcoin Premium Index measures the spread between Bitcoin’s price on Coinbase (a top U.S. exchange) and the global market average. It’s a key indicator for tracking U.S. capital inflows, institutional investment enthusiasm, and shifts in market sentiment. A positive premium means Coinbase’s price is above the global average, typically signaling: strong U.S. buying interest, active inflows from institutions or compliant funds, ample USD liquidity, and broadly optimistic sentiment. A negative premium (Coinbase price below the global average) usually reflects: notable U.S. selling pressure, reduced investor risk appetite, rising market risk aversion, or capital outflows.
