This will immediately erase your old wallet and create a new one. You will also see your new seed instantly in the Terminal window. Make sure you safely store your new seed.
Go back to the Wallet tab, and use the new seed to unlock your wallet. Since this is a brand new wallet, your Siacoin balance will be 0 SC. Enjoy your new wallet!
