That's quite a privileged point of view. Take a look at: https://en.wikipedia.org/wiki/Hyperinflation#Notable_hyperinflationary_periods. In the crypto world, this is the very definition of a pump and dump. Except the pumping in the fiat world is the money supply and a dumping is the value. As for scam coins, I disagree, the scam isn't usually the currency (we'll, not more than fiat) it may be created and used to facilitate a scam, but unless the creator programmed in a flaw that can be taken advantage of, it currency itself isn't the scam. And since scam creators are usually lazy, ignorant, or just optimising for returns, most of the code behind their coins have been forked from other, more legitimate crypto projects.
