Nobody is praying for an apocalypse. On the contrary, there have been people sounding the alarm on the reckless policy of the Fed for decades, but since it falls on deaf ears and any reformation of the Fed seems increasingly unlikely, anybody who realizes that kicking the can down the road is not a solution to anything has no real option other than to opt-out of the fiat system and Bitcoin or Gold are the only real alternatives. Bitcoin has several advantages over gold which would make it more desirable if there were a shift back to hard money.

You seem to think that the dollar crashing will crash civilization. There are dozens of cases of hyperinflation hitting over the past century, particularly since the end of the Bretton Woods agreement - they cause temporary turmoil, and those most affected are the poorest, but recovery happens fairly quickly provided the government steps out of the way and deregulates to allow the economy to repair itself.

If you don't want to be one of those most affected by hyperinflation, it might make sense to have a plan in the event that the USD hyperinflates - since there's nothing to suggest it will be any different to other currencies. I'm not necessarily trying to predict the future, but I'm planning ahead for a potential scenario. To me one that looks increasingly plausible and is merely a question of when, not if.

Part of that planning includes being able to transact if there are disturbances in internet infrastructure. This is why you can transmit and receive Bitcoin over satellite and radio already. The internet will quickly heal because there will be a financial incentive to provide it - earning bitcoin in exchange for the provision of bandwith.

Also, in regards to coiners becoming kings - it is likely that people with significant bitcoin holdings will keep a low profile, else they put a target on their heads. Extravagant displays of wealth seem unlikely and foolish.

There will be no apocalypse because the replacement for the dollar is being built already and it will simply absorb the fallout when the dollar fails. There will be some havoc caused, but the transition will likely happen in steps, with the 2017 bull run being an example of one such step - where a large influx of new users happens at once, followed by a bear market, followed by another bull run which exceeds the previous one.

You don't have to have a backup plan and you can believe everything that your government and "experts" spoon feed you, that's fine too.
