"each elementary operation implies a minimal expense of energy"

If the amount of needed energy is bigger than the whole Solar System, well, Bitcoins is not only protected by the rules of Mathematics, but also by the laws of Physics.

If the amount of needed energy is bigger than the whole Solar System, well, Bitcoins is not only protected by the rules of Mathematics, but also by the laws of Physics.

I don't think so. A mathematical breakthrough could mean that fewer operations are required than previously expected.
