The only perk for ZEBEDEE users who have an Bipa account is an easier and linked UI.
I see.
BitSTAMP has integrated with Zebedee, and that is BitSTAMP's only support for LN -- to withdraw to Zebedee wallet. So I was wondering what this integration with exchanges is all about if the exchange itself supports Lightning Address for both deposit (to your Lighting Address given by the exchange) and withdraw (to any Lightning Address).
But as you describe it, this Bipa integration is simply an additional convenience for Zebedee wallet users (so that they can quickly and easily withdraw to Bipa). That's cool.
