What is the smallest sized possible black-hole? And what are the implications of the answer to this question?
According to cosmologic observation, the smallest black-hole ever viewed from Earth is roughly 3.8 solar masses.

However this observation does not establish the lower limit to achieve a stable black-hole. For one thing, that structure has been growing ever since its creation and is observed growing today. For another, there are several different models that do seem to suggest the lower limit of stability for a black-hole to be much smaller than 3.8 solar masses.
I posit this discussion not out of pure whimsy. The deductive Dominium analysis, on which I am working, asserts that in the primordial Universe, long before CMB, mini black-holes were formed near the centers of each galaxy. Those of a similar type to the galaxy itself (matter in the case of the Milky Way) went on to form the central AGN, while opposite-type MBH (antimatter for the Milky Way) either were trapped in the MAC structure or were ejected and are now recorded as “dark-matter.”

Unfortunately, the Dominium model is deductive, therefore it is only useful in supplying the big-picture narrative, but is unable to supply numeric specifics, such as the exact lower limit of the mass needed to achieve MBH stability. Hence I am quite interested how folks of this forum can weigh in and explain nuances of different arguments that are floating out there.
Specifically, of theories that do use numeric methods, there appears to be both agreement in general terms, but disagreement on specifics. It appears that all theories concur that MBH can be stable for all sizes larger than one Plank mass, which is about 2.0e−8 kg or 1.2e19 GeV/c2..

Although, the common understanding is that below one Plank mass, MBH will evaporate away; this belief is not assumed by all.

Most recently, there are even those who have asserted that MBH could be much more stable than originally assumed

So the question is: which is it & why? What is the smallest size for a black-hole to stably exist? And what are the implications of this debate?
