Not really getting how this bot works or how it's useful... What are its application?

User friendly, the Telegram base users is 60m so potential access to lots of people is pretty huge.
But I think the major use is Coinbase users can access their account through Telegram or a Getgems wallet.
I guess another step toward wider adoption.
Seems nice, but I definitely wouldn't want to connect any of my Bitcoin related activities to a chat app.
Is this too much privacy-paranoid?
The session with coinbase is SSL encrypted from start to end, the bot uses oauth2 implementation and guidelines on top of Telegram encrypted protocol.
