PLEX is an in-game item that can be traded for millions in ISK, and to pay for Omega Clone State game time, ship and character customization, plus MCT and more. Even very much time to succeed in the game. One way to save time on routine and progress faster is to invest some real money into this game – for instance, to buy eve items needed to fit a ship. Just like in the real world, in the in game universe anything can be bought for the in game currency. That's 27.22 kg. The smallest unit of wheat you can get in EVE is 1000kg, so that's about $11831.37 per unit on the market. NPCs sell one unit at 90 isk. That would make one isk about $131.50. So incidentally, in terms of today money, making one isk a day is still more than twice the amount of a full day minimum wage before taxes.
