Now that is a good question.

Unfortunately there is not a good answer. Our system of maths breaks down inside a black hole so we cannot calculate what is happening.

One theory is that they evaporate by Hawking radiation. Another that they will all coalesce and form a giant black hole with all the matter in the universe, which may explode and start the whole thing off again.
