Any other promising use case of crypto?

As an engineer, i still could not see how crypto can be use to solve painful problems. I understand that it can be used to store and move wealth without geographical restrictions but that is currently being cracked down and soon will be regulated.

Besides the above, I struggle to see what other potential mainstream use case crypto can be used. So for my research purpose, I would like to hear your opinion what other areas crypto likely going to be used and adopted?

To be frank, current solutions in the market are mostly around trading. It seems everyone is trading commodity with each other but the commodity is not translated to any real world value.
