1 worker produce 81.86Kg of Grain (as in today)
and let's suppose that we pay 45$ for the worker,
If we sold the Grain for 0.25$/Kg as the offers in the exchange today, You'll get 20,465$ -before paying the worker-
so there's no way that someone would put a sell offer in that price!
other prices that we can afford as buyers and sellers:
0.61$/Kg = which comes up to about 50$ (before paying the worker), so maybe 5$ a profit from each worker.
0.75$/Kg = which comes up to about 60$ (before paying the worker), so maybe 15$ a profit from each worker.
how I do my calculation? = Production Speed X the price that you think is right
in our case : 81.86 X 0.75 = 61,395 - 45 (worker wage) = 16,395$ Net profit.
so guys what do you think? what's the best price to trade Grain? (personally I think 0.7 or 0.75 $/Kg)
