Cryptocurrency, blockchain, and De-Fi are the fastest growing technology in all of human history and have created more wealth faster than any investment strategy.However, it's speculative and not right for everyone. For those seeking a relatively lower risk way to profit from the crypto gold rush, there are two strategies that I personally use.High-yield crypto savings accounts, using stable coins backed 100% with US dollars, can be a reasonable alternative to junk bonds, and offer an 8.25% yield.Combining crypto with high-yield blue-chips like BTI, can pay you up to 4.1% yield that grows over time, and pays you generous and safe yield today while waiting for potentially life-changing returns tomorrow.A modest 1% to 10% allocation to crypto, including yield farming stable coins, can significantly increase your retirement portfolio's returns, with only modestly higher volatility. Using appropriate asset allocation and risk management, through semi-annual or annual portfolio rebalancing, is how you can minimize risk to what you can personally stand, and potentially achieve the rich retirement of your dreams.
