  According to the horizon fluff proposal microstates of a generic black hole
belong to a certain subset of near horizon soft hairs that cannot be extended
beyond the near horizon region. In [1,2] it was shown how the horizon fluff
proposal works for AdS3 black holes. In this work we clarify further this
picture by showing that BTZ black hole microstates are in general among the
coherent states in the Hilbert space associated with conic spaces or their
Virasoro descendants, provided we impose a (Bohr-type) quantization condition
on the angular deficit. Thus BTZ black holes may be viewed as condensates (or
solitonic states) of AdS3 particles. We provide canonical and microcanonical
descriptions of the statistical mechanical system associated with BTZ black
holes and their microstates, and relate them. As a further non-trivial check we
show the horizon fluff proposal correctly reproduces the expected logarithmic
corrections to the BTZ entropy.
