What’s your best argument against crypto?

We are going upwards to some extent for some weeks right now and it seems we all feel some positivity. We see a lot of arguments for different coins and tokens.

We barely see good arguments against crypto. So what are your best arguments against crypto?

To me one argument is that I don’t really see use cases for crypto besides financial services.

Another point that is I very hard to keep track of the developments in crypto. I for instance, focus on Bitcoin and Etherum for my investments, although I’m interested in other projects I feel I need to put too much time in them to be up to date.
