According to Cas Abbé on Twitter, a major Bitcoin OG wallet was hacked, resulting in the theft of approximately $330 million worth of BTC. The hackers subsequently laundered the stolen funds by swapping Bitcoin for Monero (XMR) across several exchanges, making the trail harder to trace. This event stands out because the compromised wallet is not linked to any known crypto exchange or institution, suggesting it belonged to an early adopter or significant private holder. Traders are monitoring exchange inflow and XMR trading volumes closely for unusual activity, as such large-scale laundering can impact both BTC and XMR liquidity and price action in the short term (source: Cas Abbé Twitter, April 28, 2025).
