I understand that black holes are still little more than a theory but can they move? It is said that there is a black hole in the middle of our galaxy. If there is when are we gonna get sucked in?

First of all there's plenty of very compelling observational evidence that black holes do exist.
Yes, they do move. Our solar system is perfectly safe from the super-massive black hole at the center of our galaxy. Remember, if you move twice as far from some gravity source its strength weakens by a factor of four and we're about 25,000 light years away from the Milky Way's central black hole. Our solar system IS drifting towards the center of the Milky Way, but at a speed of 10^ minus 10 meters/second our planet will be toast long before we ever get there.

Black holes can move just like any star of the same mass.
There is now little doubt that there is a back hole of 3.6 million solar masses in the center of our galaxy---the observations are quite detailed.
A "theory" is the best thing a scientific idea can be. There's no way to be "more than a theory".
We're in orbit around the Black Hole in the center of the Galaxy, along with a lot of other material as well. We're not going to get "sucked in" anytime soon, and in fact this may never happen.

All matter in the universe is moving. Besides our orbit around the sun, our solar system is moving inside the galaxy. Our galaxy is moving with others in our "local" space and this group is moving in the universe.
We won't get sucked into our galaxies black hole due to the already existent balance of gravity and spin.
Why does everybody have to qualify their question about black holes as "just" theory? Most scientific findings are theories - they have yet to be proved wrong, but can be in the future. However, they are believed to be true as we understand things now.

Yes, Supermassive Black Holes Move Twice As Fast.

Movement is always relative.
To speak of movement as an absolute always means that the speaker is making an assumption of that which the movement is relative to.
If you are speaking of the movement of a black hole with respect to the fabric of space and then start doing a deeper analysis of what you are talking about then you will end up asking yourself questions like "How fast is a containerless litre of vacuum moving with respect to the vacuum of outer space?".
This is what the 1887 Michealson-Morley experiment, the Lorentz-Fitzgerald contraction theory and Einstein's theory of relativity are all about.
If you are moving with respect to the black hole then it is moving with respect to you.
I doubt that you or I could accelerate a black hole but something hitting it might,
I doubt that we will get sucked into a black hole for billions and billions of years if ever.

Everything in the universe is in free fall, including black holes. We are not under the influence of the gravity of the black hole in the centre of our galaxy.

As far as I know we are safe, meaning our planet is not going to be sucked in by the black hole. Black holes doesn't move I believe, but they can eat another black holes that makes them more bigger and powerful.
