Billionaire investor Stanley Druckenmiller's family office, Duquesne, has made a significant investment in MercadoLibre, purchasing $10.1 million worth of shares since Q2 2024. The investment was bolstered by an additional $11.1 million purchase in Q3 2025. MercadoLibre, a leading e-commerce and fintech platform in Latin America, has received 'buy' or 'overweight' ratings from major financial institutions including Citigroup, Morgan Stanley, and Barclays, with price targets reaching up to $3,000. The investment comes as the fear and greed index indicates positive sentiment, making MercadoLibre an attractive option for investors. While MercadoLibre garners attention, altcoins continue to be a focus for those seeking diversification in their crypto portfolios.
