What to do with my zp and GP?

So I bought 100k zp and I'm going to spend 80k of it on crates, that's 100 crates, and the rest for exp+ stuff. The two crates I'm thinking about are deagle scope and ak scope, but I don't know which one to go for first. The draggle scope cause I only have 2 pistols, deagle and usp, so really only 1. But the ak scope cause I only have 3 rifles, ak-47, m16a2, and m4 silver. And about how many coupons will I get from 100 crates I have 23 of them now, cause I want the deagle gold from coupons, I don't care about how it looks. I dot want the m4 custom cause I have m4 silver.

And for the GP I have 80k and I'm going to spend it all on deagle camo crates cause I want to have 4 deagles cause I'm going to be using 4 bags. And with the GP I get from the crates I'll use on deagle camo if I haven't won it, and the xm8 if I won it cause I always liked the xm8.

Right now I just reached master sarge, I have AWM, AK-47, deagle, M16A2, M4 Silver, RPK, and USP.
