are only assuming it from your own understand. Bitcoin is something good that is transparent and don't allow its users to be oppressed by government and the banks. Therefore,bitcoin can never be used as the currency of the apocalypse.

Only one currency will be forced on the people to use and anyone without the mark of the beast wouldn't be allow to use that currency. Bitcoin is open to everyone and it gives privacy too. No one can know who own a bitcoin if you store it in your private wallet,bitcoin will never be the only currency to exist in future because the government rules the world and every country has their own currency that was designed by their government.
