Why you should invest in Limestone and Concrete?

The chart shows a clear upward trend before the recent sharp drop (likely a temporary correction).
Iraq has 203 players, while globally the numbers are rising (Venezuela 906, Germany 683), meaning the market is expanding.
Economic link
A new player needs:
Factories
Military units
Parties
All of these rely heavily on concrete, while:
Limestone is only an intermediate raw material
Real demand is concentrated on the finished product (concrete)
So:
More players = more construction = more concrete consumption = pressure on supply = price increase.

Additional in-game indicator
-Recommended regions for concrete give +57%,
While it was before the highest goes for +61.25%
That's mean -4.25% less producing

-Recommended regions for limestone give +56.5%,
While it was before the highest goes for +61%
That's mean -4.5% less producing
Expected conclusion
I expect:
A gradual price increase for concrete after the current correction ends.
A good buying opportunity at the current price before the next construction wave.
If the influx of new players continues, we will likely see:
A temporary concrete shortage
Higher profits for concrete factories
A shift in investment from raw materials to processed construction goods

This analysis is based on current in-game data and observable trends.
We cannot predict the future with certainty, and our assumptions may turn out to be either correct or incorrect.
This is not a guaranteed forecast, but rather an economic perspective and personal interpretation of the market.
Players should make their own decisions and manage their risks accordingly.
