Trust me.. It'll be fine

From someone else who really doesn't know either: Bitcoin is one kind of cryptocurrency (the largest one, actually). There is no physical money, but it is created through something called block chains and mining (I don't know what this means). Many people like it because it is decentralized, meaning no government has control of it. My husband actually prefers a couple other cryptocurrencies, and one of them recently made a debit-type card, so you can actually spend it like normal cash. I think each cryptocurrency works a little bit different, so you have to research and see which ones you want to support.

But isn't it bitcoin from a game? And not a real life thing?

P.S. All the bitcoin jokes you have been seeing are because cryptocurrencies are really "volatile." Just like typical currency or stocks change in value, so do cryptocurrencies - except cryptocurrencies can have several extreme "swings" each day. (But overall they have been steadily increasing).

No, bitcoin is definitely a real life thing.
