Sorry if this was asked previously but im confused about PoS again... Peercoin says you have to leave the wallet open and unlocked all the time to mint. Mintcoin for example says you have to open the wallet only sometimes to catch the minted coins. How do Fluttercoin work here? Have the wallet to be open all the time to mint?
You can unlock for minting only by running:
walletpassphrase <passphrase> <timeout> [mintonly]
for example:
walletpassphrase mypassword 604800 true
