If I understand it well, for stealth addresses one can't use dumpprivkey in order to back the wallet up and the only way is to use the Backup Wallet option?
You can only dump public address's keys. Which isn't really a recommened practise if you make regular transfers, as the wallet creates a new change address with each transfer.
However, v4.1 introduced MNEMONIC seed words when you set-up a new wallet. Thats recommended alongside backing-up your wallet.dat file.
Thanks for your answer. I created the wallet and now I'd like to transfer coins from the old one. I have most of the SPECTRE coins locked in stake category, even though I disabled staking. I guess, I just need to wait for a while until they appear as available?
Right, it takes some time. Anyway the mnemonic seed is really a cool feature!
Edit: Everything looks good except for staking. I'm getting this message
Not staking because wallet is locked
How can I unlock the wallet? I somehow can't see any such option.
Check under options, if staking is enabled.
As well you have a little lock icon on the top right. When you hover over it, it should say: "wallet is locked". By pressing on it, it will ask for your password if you set one to unlock it.
