Sadly, a mini black hole would suck up everything around it. Much like a tiny Katamari Damacy, it would quite quickly consume everyone and everything around it. Of course after not too long it would become a regular sized black hole.

Some mini black holes do not grow into black holes. They collapse. The issue is that they aren't stable for any decent length of time. Fractions of a nanosecond.

A capitalist haven, think of how many black holes one could sell!
