As akyoda32 has mentioned, it's very hard to tell on height/weight alone, we could ideally do with a bodyfat % before advising you on anything.
However, going off your BMI I would like to point out that it's quite low and not far off the "Underweight" category, although BMI does not really count for much because someone could have a low value but have little muscle mass.
Going off your picture in your avatar, if that is you, then I would suggest you look pretty well cut already to me, abs showing, reasonable pecs for someone of your weight. So it all depends on your aim, if you are trying to get bigger then I would say bulk, if you are trying to get more defined then I would say cut a little bit more and those abs will stand out.
I guess it all depends on what weight class you want to wrestle in. I don't know much about wrestling as it's not a common sport where I live so I just presume there are weight classes.
But based on your picture you have a good base on which to add quite a bit of muscle mass.
