Teen Cryptocurrency
I have 3 nieces, 10, 12, and 14. Last year, I gave them OpenDimes for Christmas. My plan is to challenge them to see if they lost them and point out how much it's worth next christmas when I give them more bitcoin. I expect them to waste the coin on teenage shit at some point and I will keep pointing out how much they would have if they hodl'd. Kind of a life lesson.
