This text is one of the arguments against buying a crypto value ..
Namely, FIAT money has its own backbone, much more solid than bitcoin and that is the support of the central banks, regulation of the banks (provided security) and is supported by weapon industry if needed. If tomorrow bitcoin failed because of someone hacking the exchange, none of them would blink.
The beginning of the text is typical of doom porn.
Furthermore, bitcoin is used as a hedge towards the crisis as an auxiliary argument. Right now gold has that function. Calling on someone to come and say that the euro is not worth anything, nor is the dollar ... I do not know what to say.
The last who said it was underground - I mean Gaddafi and Saddam. Putin can not 'strengthen' because the Russian economy is of the size like - Spain.
Can you imagine that Spain is beginning to blackmail the EU and the US? I cannot!
The only one who can say 'no' to the dollar and the euro is China, and China will not do that because they are trading partners. Also, China has a lot of American bonds, so that financial assets would have been defective in its possession, as this would lead to war.
If China comes and says that the USD / EUR is worth nothing, then it will do so to replace it - Juan, and not with the bitcoin that is also banned in China anyway.
