Add some educational information to the final page to let user know what they can do with their Tokens.
Might need some some content creation.
Some feedbacks ideas from previous discussions:

It would be cool if there was a page which described different levels of DOT holdings and things you can do, and how you can do it:

1 DOT: ED
5 DOT: Basic TXs, Remarks
10 DOT: Democracy Voting
20 DOT: Register an Identity
100 DOT: Participate in Staking
