Things do not look so good right now that we have tainted coins floating about. There is so much ambiguity, no legal definitions, no clear answers to who owns what from the original chain, anytime ETC moves all one needs to do is bother an Exchange and say that they are stolen funds on the move. Does an exchange want that? To spent its time and resources reassuring itself that the ETC is allowed to be exchanged?

This does not bode well for the future of ETC. Fungibility.

All ETC regardless will forever been viewed with suspicion regardless. Perhaps there is enough for an exchange to make on trading that they set up a tips line for ETC from now till for ever, a dedicated tracking team to filed false tips that stolen ETC are on the move. This remains to be seen.
