Do you mean the new chain will have a "maximum" of 10 million? ... I take it Cryptopia doesn't want to participate in the swap?
10 million is the minimum supply . After swaps done by coinexchange and manual swaps are completed we would burn the extra supply which has not been claimed out of 10 Million coins after the close of manual swap window .
Please move your coins from wallets and other exchanges to coinexchange for swaps .
