How many coins I can get daily if I start minting from wallet?
it depend on your stake
interest is 30% annual
Is keeping the wallet unlocked while minting safe from hackers?
It should be safe in the cases where the wallet.dat is stollen (the majority as far as I know).
Not sure if there are cases where coins are sent directly from the users' PC through RPC Api.
