for all you folks that dont know... here's a small guide not to be a complete scrub. can even be done as a lawless solo player.
Gold is easy to get when you know what to do.
-first start by building a market on a coast. set up a warehouse next to it. then, put between 3-5 farmhouses or specialty resource gathering structures around said warehouse, making sure they're all connected to the warehouse. remember other companies farmhouses, warehouses and markets can block you from building yours. destroy them. now, start setting up trades with your neighbors. doing this you can make between 5-10k a day with just one market. the more markets the more passive income but that also means more territory to maintain.
-now that you have enough to buy a ship in just a day, save that gold to craft an armored shipyard so you can at least keep your ship while away from game. (youll thank me later) also, you can store your gold in the shipyard and not many people are going to spend the time and cannon balls it would take to destroy it and take your gold.
-now that you have your shipyard and ship, its time to make real money. head to sea. look for the trade controle node islands. head to it. scan the island and look for the tax bank. destroy it and pick up the bag. it will contain all the taxes from all the trades that go on within its territory. depending on when the island owner last picked up the gold, the bag could be between 10k-200k.
BOOM. you now have the knowledge not to be a complete noob. get out there, sailor.
