You know, I tell people to get into Bitcoin not for the its amazing world changing potential, but to get in just to experience this market.
Next time just suggest that they set a few dollars on fire every day or two. That will save them from wasting any extra time and give them the same experience.
Even losing money often involves learning something. You don't learn anything from setting bills on fire other than that paper bills are flamable. Here, you at least learn how financial systems work, how things are valued, why the value drops, and how to avoid that in the future. Even if costly, it's still a very valuable lesson about something vast majority of people don't know about.
