When complex systems collapse, they always revert to a more primitive state.
Correct. Food, security, medicine, and sin products. Not some silly silver dimes that have no primitive utility and last used to be currency 50 years ago (and for the most part not really currency all over the world since a century ago).
You lack the capability of clear logic.
There is no viable scenario on earth where the global economy experiences any type of serious meltdown and immediately jumps to an even more complex state (bitcoin).
Of course there is. Technology would be precisely the way humans would try to subvert the crisis, because it is the most efficient. Smartphones use very little power (can be charged with a solar panel or even a hand crank) and WiFi mesh networking technology is already being looked at by Google and others. Necessity is the mother of accelerated "seat of the pants" innovation. We have the hardware in everyone's hand. We programmers can add mesh networking in a heartbeat when we must have it.
We don't absolutely have to use cellular towers. They are more efficient, but we can get low bandwidth needed for crypto-transactions done in other ways such as WiFi mesh and/or HAM radio.
The paper bills will be the main thing imploding because the coinage has an actual floor to it. The cost to produce a nickel varies between around 5-8 cents and a penny is around 1.7 cents, so it's plausible that several denominations of coins would just keep on trucking and be utilized even if the paper currency went to zero.
What a tinfoil hat dolt. Iron used to be a precious metal. The commodities are on an inexorable decline in relative value. Did you entirely miss this point from my famous essay which CoinCube cited in the OP of the Economic Devastation thread. There is a chart there from the Economist magazine which would be very eye opening for you.
Peak oil is propaganda lie
Peak oil is obviously real because we extract all the low hanging fruit first (the cheapest oil)
Obviously you've been fooled by Rothschilds-funded propaganda and then you claim you don't want to be his slave. Lol.
r0ach you have a lot to learn about the realities of the world. And I don't have the time to teach you.
I will just tell you that my father was the West Coast Division Head Attorney for Exxon in the 1980s and after a General Counsel for THUMS a consortium of the major oil companies. I know some things you do not know.

Besides we are moving away from carbon-based fuels and generation via nuclear energy, solar, hydroelectric, and geothermal. New technological breakthroughs in these areas plus battery technology will obsolete carbon fuels.
WHAT battery technology? I sure as hell don't see it.
A confluence of technologies is actively transforming our energy economy as we speak.
There is no strong case for silver. It is more volatile than gold, less liquid, and there is no supply crunch problem. The precious metal promoters are fooling you with lies and propaganda.
It is estimated that within around 50 years we will run out of a lot of rare earth materials used in industry.
BS. Some entities tried to corner the market (mines). There is abundance of rare earths. You are a Malthusian fool.
The timeline for silver is even sooner, around 20-30 years. There is not a silver supply crunch problem, there is a supply crunch problem for everything.
Nonsense. There is so much silver in the ground, we will never get it all out in 10,000 years. Also for example, as needed by necessity technology will advance and there will bots that can follow an ore vein and mine at the same time as exploring.
Blah, blah. More self masturbation, armchair useless talk.
