Balancer attacker cashes out $48.7M ETH for BTC, leaves 1k ETH behind
A Balancer attacker reportedly converted 21,000 ETH (about $48.7M) into 617 BTC over three days, leaving roughly 1,000 ETH in the hacker’s address. The move appears to be part of ongoing liquidation of stolen funds.
Traders are watching whether the remaining 1,000 ETH gets liquidated, which could drive further market selling pressure on Ethereum (ETH). The article links this flow to short-term downside risk for ETH.
Prediction markets also reflect the event’s perceived certainty. Polymarket’s “crypto hack exceeding $100M by Dec 31” is priced at 100% with 251 days left. However, the piece notes low/no volume on these contracts, meaning the “100%” level may reflect near-certainty rather than active two-way trading.
For ETH specifically, the “Ethereum above $2,600 on Apr 26” contract is around 0.2% across sub-markets, implying limited expectations for a rebound in the next two days.
The report urges monitoring on-chain investigators (e.g., ZachXBT) and analytics firms (e.g., Chainalysis) to track subsequent transactions. Any additional large ETH outflows tied to this or similar exploits would likely remain the key catalyst for ETH volatility.
Bearish
The report centers on a large Balancer attacker converting stolen ETH (21k ETH) into BTC and potentially liquidating the remaining ETH. Historically, sustained attacker liquidation—especially converting into a different major asset—tends to create persistent sell pressure and raise short-term volatility. Similar patterns have been seen after large DeFi exploits, where the “slow unwind” phase often weighs on the affected asset (here, ETH) longer than the initial hack headlines.
Short term: the key bearish mechanism is incremental ETH supply hitting the market if the remaining ~1,000 ETH is sold. The article’s mention of low expectations for ETH reclaiming $2,600 soon aligns with this. Additionally, priced-in certainty in hack-related prediction markets can amplify risk-off positioning, even if contract volumes are thin.
Long term: unless further related outflows occur, the market may eventually stabilize as liquidation completes. But until on-chain evidence confirms the attacker is done (or funds are halted/frozen), traders may keep hedges or reduce exposure.
Net: given the already observed ETH→BTC conversion and the explicit risk of more ETH liquidation, the likely trading impact is negative for ETH in the coming days.
