  It is argued that the superconducting and pseudogaps represent different
coexisting phenomena, and this observation speaks against the
precursor-superconductivity scenario of the pseudogap; see, V.M. Krasnov et
al., Phys. Rev. Lett. 84, 5860 (2000). We present brief comments showing that
the experimental facts of this paper do not contradict to the observations that
the pseudogap in underdoped Bi-2212 smoothly evolves into a pseudogap above
critical temperature $T_c$, and the large energy gap below $T_c$ is mainly of
superconducting origin. We show that appearance of this pseudogap is closely
related to a new energy scale observed recently.
