So basically if you haven't withdrew SXC before the merge mine activation (which looks like it happened Dec 30th), your coins are lost?
Cryptopia is allowing withdrawals until January 21st.
I withdrew about 30 minutes ago, but I have no hopes of receiving it after finding this thread.

Someone really fucked up the scheduling of this activation. Special thanks to everyone at Cryptopia, SXC Team, and myself for losing my SXC.
