Is the temperature of a black hole absolute zero?

Since matter keeps getting denser and denser, and moves less and less to the point of absolute zero where nothing is moving or vibrating, and it is giving off no black body radiation, would a black hole be absolute zero? It fits the characteristics of what something would be like at absolute zero.

This was thought to be the case before the 1970s, but Bekenstein and Hawking showed that black holes actually emit blackbody radiation, albeit at a very low temperature for realistic-sized black holes. The temperature is inverse proportional to the mass, and for a solar mass black hole, the temperature is about 60 nanokelvin. In practice this is effectively zero, because the cosmic microwave background is a scorching 2.7 kelvin in comparison.
