Not as far as I understood, no. Black holes do not suddenly start sucking all matter into them; they have the same gravity as the stars from which they resulted from.
If you compress a penny down to a black hole, it will still have the same mass and the same gravitational pull as the penny had before. (i.e.: not very much)
Oh wow, I didn't know that. I figured it would do exactly what you said it wouldn't, that it'd start sucking everything up. Interesting! Thanks for letting me know!
