Imagine investing in bitcoin 10 years ago...Even 100 dollars invested at that time, would make you a multi millionaire today. Unfortunately, there is no time machine to go back in 2010. I believe that some day cryptocurrencies and electronic money will fully replace cash, this is something which we cannot avoid. I hope at that point taxes will be easy, because nowadays it's a pain. I use the service of https://taxfyle.com/ to do the taxes for me. The price is too low for this quality I would say, saving a lot of money and time using their service.
