Hawking radiation states that a black hole will slowly dissapate matter in the form of Hawking radiation.

Let's try to define some terms.
A black hole is an object with tremendous density, such that it has an event horizon around it.
An Event horizon the radius around the black hole such that the escape velocity exceeds the speed of light. Earth has an escape velocity of about seven miles per second. Since the escape velocity is greater than the speed of light, we cannot see it - light cannot emit. Light is emitted from things nearby the black hole, which is how we identify candidate objects. We are not certain that we have actually identified any, but we have seen events that could be well explained by the existence of black holes ( Cygnus X-1 and quasars)
So, a black hole isn't really a matter of mass, but having a lot of mass in a very small space - high density. Current theory has these made at the time of the big bang, or following the supernova of an extremely massive star.
Whether or not the mass is in a black hole or not, it still provides the gravitational force and attracts other mass. There is no limit, given mass close enough to be attracted by the black hole.

a black hole will keep gobbling up surrounding matter till it runs out of stuff to gobble up. The "Event Horizon" will grow larger as in consumes more matter. The "Event Horizon" is the point at which light can no longer escape from the black holes gravitational influence. At the center of our own galaxy is a massive black hole about 2 billion times the mass of our own sun.

Some black holes are believed to hold billions of time as much matter as the Sun. As far as I know, there is no upper limit.

Hi. The amount is only limited by the amount of matter that contacts it. The hole only gets larger. The 'hole' in this context means the so called 'event horizon'. VERY hard to visualize.

If a black hole could exist it would be capable of ingesting all the matter in the universe.
It would sit for eternity doing nothing!

How about infinite. The sun when it starts to collapse is accelerated by the increaseing gravity. The mass will increas to infinity and they u know is that the gravity in the middle of a Galaxy holds everything in orbit that is several light years across.

There is no limit.
