But rubber tires did have utility -- they were a useful commodity in trade.

Digital currency is 'air' it has little if any utility. If you can make money off of speculation -- that's fine --but don't cry if you get burned.
You either converted mining 'air' and electricity expended into a new form of air;or,
If you purchase digital 'currency' assets with hard asset national currency -- you are buying air with real cash -- keep that in mind.

Good luck to the winners ...
