people have gone on and on about inflation, buying creds off ebay, even overbuffing. I have created an amazing solution, let traders have shops, they can rent out machines to sell items and refill them at will, they should be able to close and open the shop at will also. People can sell stuff to the trader to get money, a small icon should come up in the traders window showing the price that the game would charge and pay for the item, or colection of items, the trader and other guy can agree on a price, if they do not the other guy can go somewhere else. to eliminate the chance that traders can team up and triple the price there will be a cap charging amount, like 10% over the normal price that the game would have set. The trader could also leave the shop open when he/she is logged off by seting the % of an items value for buying and selling, he/she could also have a doc or surgery clinic for implants. This set up would charge the trader quite a bit to eliminate traders from becoming all-powerful and there would still be computer generated shops. With this anyone can sell stuff they dont need to the trader and the trader can make a profit from it to make up for time not in a mission or hunting.
