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".
bitcoin core - ok fair point I put in the brackets the ticker instead (BTC), my point is that it's not confused with any of the forks.
Regarding the crisis - I don't mean crisis where the electricity stops working and those who have canned food, guns & ammo are the ultimate winners. I meant something at the 1930s or 2008 level.
Therefore I don't expect that all the banks and all the cash will be distrusted and the only way to go forward would be crypto money - this might happen at some point but probably will take one or two more crises.
