2009 or 2010.

I was working in the bee yard at my best friends house/apiary 12 or 13 years ago, during the summer/fall seasons, the radio was on while we were inspecting the hives. The news guy was talking about "a new kind of money" that had recently been released (or was going to be released?). It was called Bitcoin. Geek money, i thought. It was a sunny day, the bees were happy.
