I'm also on board with segwit but please remind me, when will segwit be implemented?
Segwit is implemented and has been recently merged for the upcoming version. Check the Github page and the commits. However, the exact details of activation have not been set yet.
No, Segwit has not been implemented. It has been merged, yes but the answer to my original question is that no one actually knows when it will be active. This is the real problem. Markets that are unable to respond to demand by the users are not free.
