What are you looking for? Ministries and missions works that utilize Bitcoin?
Not sure if there's a list out there anywhere, but my church nostr:nprofile1qqsqv6x9aeg8gd9nxw2qxuvnzakvg7qtgt8ecqpj6vwcp0656ey70hqgtq7vh accepts Bitcoin donations and holds Bitcoin as a savings asset.
I don't know of any missions organizations that have started using Bitcoin to more reliably get funds to their missionaries yet, but that was one of the first things I thought of as a use-case for Bitcoin when I first heard about it.
I'll personally be going to Prague on a mission trip with my family this summer, though, and accept any help with expenses for that in Bitcoin.
