"As people value the inflationary fiat currencies less, they will hold less of their wealth in it. Every dollar dumped back into the market means that there will be more in circulation, continuing the downward spiral of inflation. Those who choose to keep their money in inflationary currencies will lose even more of their purchasing power, thus pushing them towards moving their savings to deflationary cryptocurrencies."
