Please update to wallet v1.1. This update will stop mining rewards at block 75,000, which happens in about two weeks. This allows us to carry on coin swap basically in "unlimited" time without too worry about coin minting in the old block chain. Schedule will be a new coin launch within this period followed by coin swap . About 4.5 mil magicoins will be minted by the end of this period. We will handle the same amount of coin swap. Stay tuned for more info.
