Who is the wealthiest man in the world who made his money through illegally ways?
No, that's fine. Thanks for the suggestions. Can you also recommend any good investment apps?
Sure! Two popular investment apps are Robinhood, which allows you to buy and sell stocks, ETFs, options, and cryptocurrencies, and Acorns, which automatically invests your spare change from everyday purchases. Would you like any more information on these apps?
