Maybe people didn't lose their savings in the last meltdown but can I remind you how maybe people have lost a significant amount of their savings overnight by their governments and the bad monetary policies those governments pursued? The devaluation overnight of the Argentine Peso(where incidentally Bitcoin is very popular), the devaluation of the Thai Baht. These are all incidents where people went to bed and woke up much poorer than they were the day before. How about the unsound policies of Zimbabwe(do a google search for a Zimbabwe 100 Trillion dollar bill) and Venezuela that leads to devastating inflation? These were the result of politics and monetary policies that were enacted in the pursuit of those politics. Crypto currencies turn all of this interventionism on it's head.
