I need some opinions on CS:GO Weapon Case 2. Should I stock up on this?

No. waste of money. (Use this advice at your own risk)

Just wait for the next operation,buy it instanly and play as much as you can.The first day or 2 cases will be very expensive.

I did stock up. The case doesn't drop anymore, so the price will rise in 2-3 months. (probably)

I bought a bunch of them in late winter/early spring. They have barely rose up in price in about 5 months, so I don't think it's worth it. Try Phoenix cases or Winter eSport perhaps.

I bought 200 of them day after they stopped dropping(9 months ago, 380k of them)
Bought them all for 0,03 so it's 6 euro.

Today the price is 0,12 which gives me ~20 euro (tax)

Was it worth waiting 9 months? Answer yourself.

They DROP but much rare like any other case .Every case still drop even bravo case or weapon case 1..Anyway weapon case 2 is a case with stupid skins..
And of course the case is so "expensive"...As I said earlier HAVE RETARDS SKINS..

well, the Bravo Case is selling for 4 bucks now. But I don't have the patience to wait for prices to rise. Don't know about you

It is so cheap i dont see why not waste few dollars to get few hundred of them.
You never know their price might raise one day.
And if it doesnt still you wasted just few dollars.
I would stock up on eSports 2013 Winter Case.

IMO they won't rise that much. They don't drop for around half a year and highest they were was around 20 eurocents pre-Summer-Great-Market-Crash (when nearly every CSGO item dropped their price quite significantly).

So, if you're hoping for 1000% or bigger profits, not with this case. But if you're hoping to double your $, then that sounds possible, in a half a year or more - unless another great crash happens when Valve gives another 3 new cases week after week...

So I went nuts and bought 44 of this for $0.13 each.

And yes, Bravo cases are still dropping although they are super rare. Valve must be running low on stock.
