Funny, I took a course in econometrics in 2009 just as bitcoin was coming onto the scene. It was actually the last college course I took. Definitely no mention of bitcoin then, but I'm sure somewhere in the thousands of courses being taught that btc is being mentioned. It's too big not to be at this point. I hear kids are even using laptops in class nowadays. Lol
Oh yeah it's in economic class as it's in range of common people who are much more valuable than the intended recipient
