I want to mine on windows, but have no idea how to start.... I'm on i5 unlocked core with 16gb ram and 780 GTX.
Hey! You have to wait till the mainnet is launched. You need to have Decred Wallet address as well, the wallet binary is yet to be released as well. It will be released along with the launch of the mainnet. I think details regarding mining will be clearly released in the forum at that time.
The binary used to create a DCR address for the airdrop can be used. Those are not specific addresses for airdop only but already genral DCR addresses. Binaries for mining should be released at least one week prior to mainnet, when public testnet will start. And since start of mainnet is delayed, so is start of public testnet. No, no new date was given.
