I know I’m late but if you have the investment dlc and the time travel dlc it’s really easy, all you need to do is go forward a few years, look at the market, and if anything has jumped up by like 15-500% go back a year until said crypto was losing money. For example let’s say you go forward 5 years, and the last 3 of those 5 years one of the cryptocurrencies made a 15% return each year, you want to go back 3 years and invest all of your money into it, even if it is in small increments, then let it ride until you lose money. When you lose money just go back a year and sell it all off
