And with these "freezing" tales - can your
"black hole" move?
I mean - if accreting matter "slows down and
"freezes"" according to faraway me - it 
practically doesn't change position 
according to faraway me. And, as it's 
always in the vincinity of BH, BH can't
change the position as well...

A black hole is a hole in space.

However, absolute space does not exist.

In fact, a black hole is a hole in nothing.

And the hole in nothing, he attracts the masses who pass by with his 
muscular little fingers.

Bearing in mind that all motion is relative.

A black hole can move on its own, regardless of any observer.

But relative to that observer, unless they are both moving
together. But in a universe with nothing else in it, how would
anyone know?

We can see and/or detect black holes spiraling around each other.

That is not what we are seeing.
Falling into a BH center is the end of space time.
How can the end move?

We can observe black holes spiraling around each other, some of them 
merge together...

They don't exist.
If they did they would not spiral together. They would have been in stable orbits
that have been for their life time.

If you say so.

They can most certainly merge together.

So how were they in their stable orbits first?
They would never leave that.

Some of them might be in stable orbits, and some of them might be on a 
"doomsday orbit" where they will merge with the larger black hole they 
are orbiting...

Everything orbiting, or accelerating in any way, emits gravitational 
waves. But the effect is so tiny that everything else swamps it in most 
cases. Close orbiting black holes are the exception; they have a finite 
lifetime and can be detected in many cases.

Even the earth orbiting the sun radiates gravitational waves. But the 
tugs of all the other planets, asteroids, its GR orbital precession will 
be much larger than its effect.

I think that is due to the mass of the object in orbit. I don't think 
that a photon in orbit around a black hole generates its own 
gravitational field?

So, what with these "freezing" tales?

I mean - if accreting matter "slows down and
"freezes"" according to faraway me - it
practically doesn't change position
according to faraway me. And, as it's
always in the vincinity of BH, BH can't
change the position as well...

Well, the object falling into a black hole does not freeze at all. The 
observer observes them to be in a frozen state. This does not mean that 
the object is frozen.

If you fall into the end of space time by gravity
how can there be any more motion?

I did not mention an end. Perhaps it is a _new_ beginning?
