Making money - pve (what there is of it) is one of the easiest methods. This includes missions, trading, salvaging (and ninja salvaging
) and even scamming. Level 4 missions can net upto 40 million an hour once your skills are setup well and you have a salvager buddy willing to roll in your wake. Hell, i've had level 2 and 3 missions net me 10 mill or so an hour with good salvage
Its possible to profit from pvp, but only if the other guy(s) fit faction/officer/deadspace and kindly die and leave it you!
Good thing with EVE is you can pay for gametime with ingame currency. As long as you make enough to do that and still have some left over your game will feel more fun and less like a job. Although monthly sub by CC isnt too bad to be honest.
A 60 days GTC costs 550 - 600 million isk - an account doesnt have to be active to purchase one of these, just needs to have the money in its wallet.
A "PLEX" sold in game that extends an active account by 30 days, currently goes for 335 million, but prices are trending down on these as they are so new.
Personally I do a little of everything for money making. Especially trading, scamming contracts and also buying random gear and selling it at a markup in mission systems and low sec hubs where it is often needed, especially by those who fly something because they can, not because they should! I have a couple of passive income streams - one is in danger of going away soon, but thats a negotiation issue on my part to fix and the other is RnD datacore whorage - that net me quite alot of funding a month. Suffice to say I can pay for all of my accounts with isk monthly and still turn a profit.
