Can I live off the interest of 2 million dollars?

I'm curious, can one really sustain a living solely from the interest generated by a sum of 2 million dollars? Given the ever-fluctuating nature of the financial markets, including cryptocurrency, how feasible is it to rely solely on such passive income? Do you think the returns would be enough to cover daily expenses, considering inflation and potential downturns in the economy? Or would it be wiser to diversify investments and have a more comprehensive financial plan in place?
