Why else do you buy PLEX? Sigh, if anyone reading this doesn’t know the answer I envy your innocence. Virgin eyes and ears can skip my post.
People farm (or bot) to put their unused computers to work getting massive amounts of ISK. There’s another post here in general discussion where I explain how I saw one guy botting about 1.7 trillion isk a month.
This isk is used to buy PLEX. But seriously, 1.7 trillion isk will buy 450,000 plex…enough to plex an account for years (off of one month of botting). What is this person(s) doing with all that other PLEX?
Selling it on the black market. In other words converting their computer time to real money.
RMT sites, and other places will pay you for your in-game assets in real world currency. That means if I had enough free computers, I could set up a bot farm and go off living my life while my bots made me cash. In our example in my other post 1.7 trillion isk in a month is roughly worth about $15,000(usd) (at CCP’s sell prices). But we have to realize everyone is taking their cut here and there.
The 0.0 Alliance/Coallition is going to get the first cut for allowing you to operate in their space. Lets say they take 1/3.
Now the service that performs the actual conversion from in game currency to real currency needs to take their cut. Right now RMT sites are taking about 1/2. They are buying 1bil isk for $3 and selling 1bil isk for $6.
So what does that give us? In my example whoever was running those 8 super carrier bots out in NULL is currently paying about 600mil a month in rent to the alliance, taking 1.1tril a month to convert to cash and putting about $3500(usd)/mo in their pocket.
