you just need to have unlimited time, at 3% annual interest, it takes 77.89 years to 10x your money. it just happens that 532 years is 6.8 times 77.89 years, therefore you would just put a 1 million multiplier on your money anyways. And putting 1 million multiplier on 1 million dollars is enough to become a trillionaire anyways

At 3% interest, you double your money every 23.4 years, how many 23.4 years do you have?
