THE major problem that bitcoin solves, is the unsustainable nature of centrally issued fiat currencies as debt, payed for with compounding interest.
The entire global financial system is predicated on an unsustainable model. If you were to invent something that replaced fossil fuel you would have invented something of equal importance. Of course the world will function for some time on both the existing economic model as well as fossil fuel, but not for too much longer.
As well, the current global financial economic model functions primarily to enrich those who developed and maintain this business model at the expense of those who use their product. Put another way, current monetary technology is incredibly expensive to use, for everyone who uses it.
In addition this monetary model is often if not always enforced militarily, or with the threat of military force.
Bitcoin solves this by providing a sustainable monetary model.
