In the past the best choice was to put it in the bank and live off the interest. Interest rates have gone down though. 0.01% is about what I'm seeing right now on a savings account, but I found 0.08% on a "risk free" investment account. So 0.08% interest on 2 million (every year). Math teaches us that continuous compounding uses the formula Pert so (2,000,000)e^((0.0008)*(1)) = 2,001,600.64. So after 1 year you've made 1,600.64. Congrats.
