i don't think there is any ultimate hedge in case of a global financial crisis. and bitcoin is not yet ready for that kind of adoption although it has a lot of potential to be one. so i'd say bitcoin would be a pretty good choice but it can't solve all the problems.
Bitcoin (core) as it's the oldest, largest crypto
"bitcoin core" is the name of a full node/wallet not the coin itself. the coin is simply called "bitcoin".
