One speaks of the Big Bang initial condition as a singularity possessing an extremely low entropy (to explain the growth of entropy throughout time to our present stage of the universe). If that singularity truly possesses infinite density, that would make perfect sense, since what would become sub-atomic particles later can have no meaningful individuality within the BB singularity when the density state is infinite. To my way of thinking the infinite density would demand some kind of amorphous 'blob' of matter/energy in a continuous rather than discrete form. To speak of micro states in this condition would have no meaning, since the blob can only exist in one micro/macro state. So far, so good (for me). Assuming black holes also exist as a singularity at its 'heart,' the same condition found in the BB singularity, namely infinite density, would also require the same kind of 'one micro/macro state for the black hole's singularity. I say this not knowing if the BB singularity is identical to the black hole's singularity. If 'you've seen one singularity, you've seen 'em all' is true, why then do we believe that the entropy is in its highest form for the black hole, just the opposite of the BB's singularity? Since I do not know for sure if a singularity has true infinite density I may be wrong in that assumption.
