You earn approximately 0.3 - 0.4th of a golden nugget per mission.



The average time it takes to complete a mission is 10 minutes.



Respectively, that's a nugget every 30 minutes.



It takes 100 golden nuggets to form 1 gold bar.



100 golden nuggets would take approximately 3000 minutes to collect.



3000 minutes is 50 hours.



That is approximately 50 hours for 1 golden bar.



Example: A desired horse would cost you 16 - 18 gold bars.



16 golden bars would require approximately 600 hours and above of your time.



That is 600 hours to collect 1 desired in-game item.



600 hours is 25 full days.



(If you play 12 hours a day that is 50 days for 1 item.)



(If you play for 6 hours a day that is 100 days for 1 item.)



I hope this translates the scale of the grind.
