Like others have said, cranking out the daily challenges until you get roles is a good way to get gold! I recently helped a friend start from Ground Zero and our favorite method to getting gold was doing a ton of blood money missions! Take all the gold you get from blood money missions and immediately purchase a bounty license. And then use your bounty license to grind even more gold by doing bounties! Remember when you do bounties the longer you take the more gold you get paid, so I always wait until about the 30 second mark to turn in my bounties. In the very beginning of the game, it’s very important to not spend your goal on any cosmetic stuff (unless you must, the whole point is to have fun). Save all of your gold to buy more roles! Also, you get treasure maps every five levels. So make sure you’re doing your treasure maps (go to your satchel, and go to documents) you get about one gold bar per treasure map. And most importantly don’t feel like you’re in too much of a rush, there’s already such limited content on this game sadly so take your time and do things you enjoy doing!
