I am exploring the eosio software, I was impressed with the ability of eosio of saving user data in a multi index table. While this property is technically really interesting I am trying to find use cases for that. Currently there exist regulations like GDPR who are considering how the user data is used. From my view storing user data (even if it is encrypted) in a blockchain does not seem to be a good idea, or maybe I have no a good use case for that.
Please could you guys help me clarify this topic?
Thanks in advance!!
