The analyst recommends adding four income-generating assets to a portfolio, emphasizing that these should never be sold. The first, SPYI is trading at $51.40 and is expected to generate income consistently. The second, QQQI, is valued at $52.74, the third, BTCI, is at $59.35. Finally, SGOV is worth $100.40 and it is a three-month treasury bond, which is a safe way to park funds. The recommendation is to use these assets to achieve passive income, reinvesting profits for long-term sustainability and indicating not specified target values for SPYI, QQQI, BTCI and SGOV. These assets can provide more income than paying rent.
