Fiat will die out soon, I am sure about that. My point in the article is not fiat currency but people buying US dollars and hoarding it taking it as safe haven asset. I can bet that fiat particularly the US dollar will fall due to negative interest rates, and that will have repercussions in global economy, people will hedge in GOLd, silver and maybe bitcoin.

It sounds great but it will be a big pain for all of us, allthough Bitcoin would rise if its takenn as safe haven.

I am sure its the END OF THE FIAT currency that's Govt. issued. Wait and see!!!
