It is well known that profinite $T_0$-spaces are exactly the spectral spaces. We generalize this result to the category of all topological spaces by showing that the following conditions are equivalent:
(1) $(X,\tau)$ is a profinite topological space.
(2) The $T_0$-reflection of $(X,\tau)$ is a profinite $T_0$-space.
(3) $(X,\tau)$ is a quasi spectral space.
(4) $(X,\tau)$ admits a stronger Stone topology $\pi$ such that $(X, \tau,\pi)$ is a bitopological quasi spectral space
