In economics class we learned about this one culture where they used these huge sandstone discs for money. I think maybe so it would be harder to steal.

A 52 digit password should suffice here my friend :)

Good point... I am no cryptocurrency expert. My cousin tried to explain it to me once but he lost me pretty quick. That reminds me, he sold his one bitcoin in January for around $700. Bad timing I guess. But he says he needed the money. Anyway, I do know a little about economics and finance and I have always been fascinated by money. Not in the sense that I want more of it (that too), but the mere fact I guess that you can hand someone some pieces of paper and get pretty much anything you want.
