Keith's way of trading was very different compared to everyone else's. To him, it didn't matter if he was taking a loss as he had no shortage of fishes. He knew that the profits made from the training camp wouldn't last forever and if taking a slight loss helped him with getting a better rank for his church, then he would do it.
His rule for trading was simple and it was to trade points for his items. They couldn't trade points directly, but it could still be done if the teams state that the credits of their work goes to Keith's team. It was similar to having a share of a company.
And in Keith's case, each team was like an independent company.
Those that did not have useful things to trade, would readily give away a part of their work's credit to Keith's team. This was because "credits" did not have any physical form and no one had access to the amount of points their teams made.
