The cryptocurrency market faced a violent cascade of liquidations on June 5, 2026, as altcoins crumbled across the board, triggering over $1.2 billion in forced position closures. The turmoil was ignited by a catastrophic crash in Zcash (ZEC) after a code vulnerability was discovered and widely publicized, prompting high-profile investors like Arthur Hayes to dump their entire positions. ZEC plunged from above $630 to under $300 in hours, though it later reclaimed some ground, leaving $100 million in ZEC longs liquidated in a single day, according to CoinGlass.
The pain quickly spread. Ethereum (ETH) broke below the $1,650 support, hitting a new 14-month low after losing the $2,000 level earlier in the week. Solana (SOL) shed over 7%, Hyperliquid (HYPE) plunged 9%, and Cardano (ADA) sank 16% amid news that its founder, Charles Hoskinson, would take a break. Bitcoin (BTC) momentarily slid to $61,000 before rebounding by nearly $2,000, seeing its dominance index tick up 0.5% as altcoins underperformed.
Glassnode data showed that more than 255,000 over-leveraged traders were wrecked in 24 hours, with total liquidations reaching $1.21 billion—$935 million of which were long positions. The chaos extended to decentralized finance (DeFi) platforms, where on-chain analytics firm Lookonchain identified over $547 million in Ethereum long positions at immediate risk of liquidation across several critical price levels. The densest danger zone sits between $1,565.72 and $1,555.04, holding $167.6 million; a break below could cascade into a $159 million cluster at $1,426.31 and a massive $220 million position at $1,361.73.
Analysis from Spot On Chain reinforced the warning, labeling the $1,555–$1,566 range as an immediate threshold. A decisive breach, they cautioned, could trigger a chain-reaction sell-off typical of DeFi’s automated smart-contract liquidations, amplifying pressure across the market. The combination of structural selling, over-leveraged longs, and cascading liquidations created a perfect storm that left the entire altcoin sector severely rattled.
