Where will be better to keep SUMO for hardfork time? On cryptopia or on local wallet? Amount will be dublicated?
We will inform exactly when hardfork happens. It will be at specific blockchain height. Fortunately, inheriting the mechanism for hardfork from Monero (that happened rather often there), it will be quite smooth. No duplicated coins unless someone want to create a "classic" version with this nasty bug (I doubt if anyone would value it).
