Which IMO will not be the USD given what the likes of China and Russia have been doing not-so-quietly behind the scenes.
It depends on the timing when/if China or Russia bring out a gold-backed currency, since they have been buying up gold for many years now. Many think that China has much more gold than officially declared right now.
Therefore, I think the "old logic" of how things work is going out the window. What replaces it in the longer term is anyone's guess, but I suspect it's gonna surprise the heck out of most everyone.
We know what system is being planned and worked on by the cabal factions in the West. It's basically the CBDCs (central bank digital currencies), which are just a way to try to get rid of cash and have total control over what people can spend money on, how much, when, etc.
It is quite likely that this totalitarian replacement of the old currencies won't find much acceptance.
As I said, whether they try to ban crypto in many countries or whether they will decide to just tax it (and try to subvert crypto) - the most likely outcome is that decentralized cryptocurrencies will grow a lot. So having some or buying during the crash seems like a very good idea.
I have no idea what's gonna happen either, so I'm not gonna bet on traditional banking alone, or cryptos alone, or anything else.
Gold and silver seem to be a safe bet, as far as not losing savings. Their prices are currently suppressed, which makes it possible to still buy some relatively cheaply.
I think the best idea is to have both gold/silver and some of the major cryptos for the time ahead. As well as food to last a while.
