A self-directed solo 401k offers a unique opportunity to invest in bitcoin and cryptocurrency through platforms like Coinbase. Since 2014—when the IRS classified cryptocurrency as property—many investors have leveraged this tax-advantaged retirement account to diversify into digital assets.
Understanding Cryptocurrency
