No black dwarfs are thought to exist. The estimated time it takes for a white dwarf to cool to a black dwarf is greater than the current age of the universe.
I think white dwarfs. This is because they are much more low mass than black holes. White dwarfs are much more common in the universe than black holes, because we have only discovered a few black holes whereas we are aware of many white dwarfs.
According to astronomers and authors Jonathan Weiner and Carl Sagan, white dwarfs - which have been an accepted entities by all astronomers for decades - require an amount of time to "cool down" that well exceeds the current age of the universe - hence there hasn't been enough time for any of them to cool down yet and become "black dwarfs".
