I'm wondering (and if this has already been answered, forgive my ignorance), if Chipmixer supports/ is going to support segwit adresses for mixing. ( meaning that if i send bitcoin to chipmixer from a segwit adress, i'll also get segwit "adress" chips.)

That doesn't seem the case as of now? Would it decrease privacy or? It would surely greatly decrease transaction costs for both parties.
It seems to me that you guys were very optimistic about both segwit and LN, https://bitcointalk.org/index.php?topic=2120757.0
