Probably less Bitcoin hashes per watt/time, but BTC is not the only cryptocurrency they can mine.

It is true but what cryptocurrency you can mine with a supercomputer that gives you a profit?

Any, as long as someone else pays for the operation.

But you can probably do a lot if your computer has lots of GPUs and CPUs on fast interconnects.
