Money making methods
Mining Ruby
Go to the mining area and just mine ruby for a couple of hours, this isn't the best method but it will give you some easy starting money as ruby sells for $850 each
Ming and crafting
Go to the mining area and mine Gold and rock and t hen make steel (It's 5 stone and 2 gold to make one piece of steel) then when you get enough steel make items like Milkors, RPG's etc etc then sell them to other players at the moment a milkor sells for $1.3Mill each
Printing
Find a good base and put up your defences (props, fading doors ) then put down a sapphire printer , upgrade it to heroic and then just keep collecting the money from it, make sure you have a weapon on your just in case someone decided to raid
Drugs
This is how I made my first million, just like printing you want to make a base and put up your defences, depending on your growing level you might have to grow carrots first and sell them to the NPC, when you get to the correct growing level grow weed and mushrooms they sell for quite a lot, keep doing it and you'll see how much you can actually make from it.
Here is a few good ways of making easy cash, just watch out for raided and scammers and you should be fine; feel free to add me on steam if you have any questions.
