BABB will allow conversion of BAX to FIAT in its platform. So you can send BAX from any exchange that supports it into your bank account, and then withdraw it. But more importantly, your GBP ( or other fiat ) will be in a bank account powered by a blockchain. This means any other entity that opens a BABB bank account can accept GBP. For instance, a crypto exchange that follows regulation can choose to accept GBP easily, similar to how they integrate cryptocurrencies.
