"Ability to trade or sell items"

#PokemonGO: As the title suggests. If only it was possible to trade items. Personally I have a lot of Sinnoh Stones and I don’t need them all.. but I know how scarce they are. If only I could trade them with a friend for dragon scales, or sell them for gold coins or stardust.Edit: I realise gold coins is wishful thinking but stardust at least would be an equitable trade. We can practically already do this with berries, ie. I “trade” and not throw away berries for 20 stardust each by feeding Pokémon defending gyms. via /r/TheSilphRoad http://bit.ly/2TiNIU2
