I think this is related to which platform you are trading on. Some websites trade OSRS Gold with players like garbage collectors, but when they are sold to players at another price, this is the least acceptable to me. So you still have to choose a formal platform, otherwise you will suffer a lot.
I usually choose to trade RSGold on the RSorder.com site, mainly because no matter what product it is, the price is always open and fair and consistent with the market price. There is also a service attitude. When I sold only OSRS Gold at RSorder, the customer service was equally enthusiastic, and they very much hope to acquire RuneScape Gold 2007 in the hands of players, because considering account security, RSorder only trade items obtained online by real players and OSRS Gold. So players will feel at ease when buying OSRS Gold.
