After carefully weighing the pros and cons of the PPX trading commission, we have determined, for the foreseeable future, that we will not reinstate it. Some pundits believe that commissions discourage market manipulation, but there is also evidence that markets are self-correcting, and PopSci believes that this will be true in the case of PPX. We took user feedback into consideration when making this decision, and we agree that eliminating the commission will allow for a more fluid market and a more fun game, overall. Happy trading. —The PopSci Editors
