Speed of Falling in a Black Hole

I was thinking about something.

On earth, you fall with a speed of 9.8m/s2, and you cap at a certain speed because of friction.

But let’s say you were falling in a blackhole, there wouldn’t be any atmosphere to slow you down (I think), the fall could be longer, and the accelereation would be much higher. So, what do you think could be the top speed of someone or something falling into a blackhole?
