Do you agree with the following question:

Hey guys,

as you may have seen I have donated my own Gold to the SC. Now we will make much more profit.
I have upgraded our Iron company to Q4. I think we shouldn't upgrade Iron to Q5 yet because that is again 200 Gold.

So my question is.

Upgrade Iron to Q5 or invest in something other? Yes means Ugrade Iron No means invest in something other.

If you vote no and you may have an idea where to invest next let me know.
