What do you think about cryptocurrency (e.g. bitcoin, dogecoin, etc.?)

I was curious what you all think about cryptocurrency. We’ve heard a lot about bitcoin and the latest seems to be dogecoin. Is this an active part of your investment strategy? Are you researching it? Are these viable investment methods?

Index funds have always been more my speed, but the more I hear about cryptocurrency, I’m wondering if I am missing out on something!
