Bitcoin is not a credit instrument. Energy was invested in the unlocking of even the first of the available units. Now each additional unit requires the expendature of a significant amount if energy to unlock. Generally a pretty significant investment in tools/hardware is required too (much like gold mining).

Gresham's law is not some eternal absolute. It actually primarily applies to sound money vs cheap money with the same face value.

The growth of Bitcoin adoption & gradual increase in the transactional use of Bitcoin demonstrates this.
