Pros:
- This will surely eliminate the data privacy issues Facebook is currently facing since there will be no central authority that could control whatever data we have encrypted there
- It has multiple features catering what messenger and emails can offer.
Cons:
- I see no disadvantages for this one but I am just concerned whether there is a limited storage for this.
- This is still on its beta phase so there is a great possibility for the users to experience computational power issues
