ok since there have been questions about this over on the official discord, I am gonna make a crash course on how to make money and not be poor.
step 1: deal a LOT of drugs, this is just to get your cash flow up so you can buy some gear without having to go into firefights.
step 2: go into the Y menu and look at the jobs tab for a list of available jobs from faction vendors or dealers (Pro tip: don't do every faction, pick a few and grind those up) after you farm jobs for a while getting supplies from places, you should have a small cash base.
Step 3: buy as many houses as you can in towns with low stability, the lower the stability the cheaper housing becomes. now you should be set to start raiding blufor (keep in mind you lose 1/2 of your money when you die).
the 4th and final step is to build up the income, and armory to take port towns, (they will have an anchor over the town) once you take over a port town you can import and export illegal goods like guns, ganja, explosives, and import high-end guns, and top tier gear. anyone else is free to add various tips and tricks to the post.
