The dollar is backed by semi rational opinions of the GDP of the nation(s) printing the dollars. The relative values of currencies shift, normally slowly, because normally economies don't tank overnight.

Bitcoin is not backed by anything. Thus it has wild swings.

It is backed by cost of electrical consumption. Its just that 90% of its value is speculation. But it absolutely does have "real value" and is backed by material reality.
