Alright, sorry this took a while, as this wasn't an obvious hack like most and during busy work time, i didnt wanna half ass this, as I had to watch a good several times.
Bhop, i'm not seeing any bhop scripting going on. His average is about 4-6 hops at a time, on flat ground. Only around 76k does he get a good bhop, but does slow down uphill.

Now as for walls, i was a bit iffy to call walls but the way he plays, i believe he is toggling walls.
59K - checks right side real quick, and then just camps and hugs the left wall, waiting for the 2 t's to pop out. 1 T pops out, he gets the kill. The second T is right behind him, but only do you see the TIP of the gun for ~20 ticks (full speed, you won't be able to see it, or VERYYY slim chance maybe. Highly doubtful). He bums rush full in, throws nade and flash bang and quickly rounds corner to the left where the other t is.

62K - fast reaction time to shoot, ~17 ticks between he sees him and shoots him. Yes he may have fast reaction time, but look throughout the whole demo, he will never bhop down there and into their without pulling out his gun only if there is an enemy. If there is no enemy, he will keep bhopping in there with his deagle.

64K - ehhhh, kinda fishy how he "randomly" decides the jump over that box, and then never does it again.

129K - see's the bot camping, pretends to check around/shoot around the boxes, takes a quick glance at where he is, smoke nade hides, even shoots where his position. Stops shooting i guess when he saw he was behind the box. Still could be checking his surroundings, but doubtful.

135k - about the throw nade at full speed, see's 2 enemies and holds back and throws it without being seen completely.

Not the best demo to check for walls, but i think we have enough to put him away.
My vote is no bhop, but he toggle walls.
