Today, it’s just a store of value that’s used to convert into other assets or fiat. It’s doing it’s job just fine and dandy. And I’m happy to hodl as long as possible. I sell only when I want something more than long term wealth.

Very few people actually create enough value to justify their consumption. You can thank fractional reserve banking and easy credit for our glutenous lifestyles.
