On-chain data indicates the rapid movement of approximately $11.45 million worth of various altcoins between multiple decentralized wallets. The perpetrators transferred roughly $1.1 million of the VIRTUAL token to a newly created address. They executed sales of this specific token in measured batches of around $20,000 to manage liquidity. The attacker still retains control of an additional $1 million in VIRTUAL tokens.<\/p>\n\n<p class=\"wp-block-paragraph\">The attacker associated directly with the Mercado Bitcoin breach actively sold off a wide array of specific altcoins. On-chain records show the liquidation of PEPE, AAVE, UNI, ONDO, and ENA tokens. The threat actor converted these dispersed holdings entirely into Ethereum.

From a technical standpoint, Ethereum is currently trading above the $2,300 mark. The Relative Strength Index for the asset remains in neutral territory despite the turbulent market conditions.
