What is something worth? A building, a pen, a stock, a cryptocurrency, gold, Intellectual property, any asset? Valuing something we own has always been more art than science.
When I was a kid and started to collect stamps, I collected them because my mom had done the same as a kid. She turned me on to the history lesson that came with collecting stamps. Then when I got to be about 15 and started going to stamp shows to add to my collection I quickly realized that there were inefficiencies in that market. The same stamp was selling for different prices at multiple stamp dealers at the same show. It didn’t take me long to realize I could buy from one and sell to another.
