I've got some all max IV Pokémon in Gen 6 but if I put them on GTS nobody will take them for something their worth. Any functional reliable location to organize trades online for Gen 6? On this site?
https://www.reddit.com/r/pokemontrades supports Gen 6 trading, allows you to specify stuff like IVs, and is really active. Plus it has a pretty tight legitimacy policy, if you care about keeping hacked Pokémon out of your game.
