I believe BTCFX and BTCLX mutual funds present an excellent aggressive investment opportunity, especially for individuals starting their 401(k) journey, particularly those over 50 like myself. Since employer-sponsored self-directed retirement accounts often restrict trading even ETFs, these funds provide a unique avenue to potentially capitalize on Bitcoin's upward trajectory. With projections suggesting Bitcoin could reach $500,000 by 2030, there's the potential for a remarkable 1300% return in one's 401(k). I'm open to hearing different perspectives on this.
