I personally think that its gonna be a mess if the popular fiat currencies die.To be honest cryptocurrencies are something I would rely more on because I think people are going to lose trust in anything else but a "imaginary" currency that can't be touched and in the same time has no connection with the government.
I hope things like that don't happen because only those who are prepared the most are going to be living good while the rest might starve.
