In the year 2010,my best friend introduce me to cryptocurrency and he advice me to invest in bitcoin. I felt bitcoin was another ponzi scheme created by scammers to scam innocent people. Today my friend is a multi Millionaire. If only I had listened to his advice,I would have become a millionaire by now.
Think about it this way in the future:
If you have $100 laying around that you wouldn't mind throwing into a fire pit, why not put it into something that is innovative and would have a first-mover advantage? At worst, you lost $100 which is one fancy dinner. At best, you could have 333-1666 BTC now (depending on when in 2010 you would have bought).
Also, playing the what-if game isn't helpful beyond you seeing what lessons you could have learned and how you can chart a different course in your life going forward.
