Dave Portnoy, founder of Barstool Sports, has seen significant returns on his recent $2 million investment in cryptocurrencies, including XRP, ETH, and BTC. After purchasing during a market dip on November 17, Portnoy doubled down on November 21 as prices continued to fall. By November 24, Bitcoin had surged past $89,000, XRP exceeded $2.20, and Ethereum approached $3,000, marking a profitable turnaround for Portnoy. The recovery in XRP's price coincided with the launch of spot ETFs, potentially increasing demand for the cryptocurrency. Portnoy's investment strategy has sparked mixed reactions on social media, with some users praising his bold approach while others liken him to market commentator Jim Cramer.
