Your reference to the claimed 1100 ATM locations is wrong. You have a link reference to facebook which is broken. Here is the actual link: https://find.arisebank.com/atm/
On this page, they show 5 ATM locations, not 1100. AriseBank is in fact partnering with BTS in that they are building an API to allow for the Arise platform to interact with the BTS blockchain.
My understanding of their partnerships is that they aren’t holding funds FIAT or crypto for their customers, rather, they are creating a unified platform to manage over 700 different currencies.
Having interacted with a Jared Rice personally, I’ve chosen to give them the benefit of the doubt but, as with anything, you should research anything you decide to invest in yourself.
