While some are supposed to have become rich due to the wonders of the digital "currency" hype one should remember that this is a giant ponzi scheme where the lucky few owe their winnings to the late-comers who splash out serious money in order to get hold of one ephemeral electronic bit - wherever that is.

Should they not at least apply the rules for the digital space?
