Pension funds are increasingly investing in Bitcoin, marking a significant shift for traditionally conservative investors. Notable schemes from Wisconsin and Michigan have emerged as major players in crypto investments, with Wisconsin holding $155 million in BlackRock's Bitcoin ETF. The rising value of Bitcoin, projected to reach $100,000, has prompted more funds to explore crypto. However, concerns about volatility and regulatory risks remain. Despite this, the trend suggests a growing acceptance of cryptocurrencies in retirement portfolios, reflecting a potential transformation in investment strategies for the future.
