"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.
