Wait for exchange listing after release of wallet.
Im think after the main net launched they list EON on their own exchange market that they created.And if you are investor you will not charge a commision fee , that is what i read on this thread.
Not only this but if you have participated in the crowdfunding campaign and have invested for you trading commission/fee will be zero for life time. This offer was only for investors and which will save everyone lot of money especially if you are big investors and trader.
