I invested in cryptocurrency, turned on into it by Mike Alfred, who I know from his Brightscope days. While I like to invest my own, I think these are investments that have no place in qualified retirement plans as an investment.
While I hear chatter that the Department of Labor (DOL) will issue guidance on the matter, I don’t bet in life, but I will bet the DOL will say that fiduciary concerns would bar an unregulated asset to be invested in a qualified plan. I think until there is some sort of government regulation (which could doom the pricing of crypto), I don’t think there is a shot at al;l that they will allow it within the confines of a retirement plan.
