Mercado Bitcoin Hack: $10.55M in Altcoins Swapped for ETH
The Mercado Bitcoin hack involved an attacker holding about $46.5 million in crypto across 46 addresses, including 3,680 ETH, 106 BTC and roughly $8 million in stablecoins, according to Onchain Lens. In a later update, Arkham reported that the attacker had converted $10.55 million in stolen altcoins into ETH. Attempts to bridge some funds to Bitcoin were stopped, while most activity shifted to new wallets. Mercado Bitcoin says customer assets and data were not affected. The Mercado Bitcoin hack adds to exchange security concerns, although the reported protection of customer funds may limit immediate market fallout. The incident also comes as Brazil tightens crypto regulation.
Bearish
The clearest direct price risk is to ETH: Arkham says the attacker converted $10.55 million in stolen altcoins into ETH, creating a potential supply overhang if those holdings are sold. This could weigh on ETH sentiment and prompt short-term caution, although the reported efforts to move funds to Bitcoin were stopped and the funds’ current destination and ability to sell are unclear. The broader Mercado Bitcoin hack may also heighten risk aversion toward crypto platforms, but the company says customer assets and data were unaffected, which may limit spillover. Over the longer term, the incident is not in itself evidence of a change in ETH’s fundamentals; any sustained price impact would depend on whether the attacker moves or liquidates the ETH. The bearish assessment is therefore based on possible near-term selling pressure, not a confirmed sale or a lasting market-wide effect.
