So, spectrecoin doesn't change my address after an specific amount of transactions like bitcoin?
Honestly I don't know of such a feature?? Must have something to do with getting a new change address maybe, but this doesn't apply to stake rewards because there is no output in that case.
You must understand how all of this works:
1. There are no "coins", there are addresses that are associated with a private key and the value of your funds for that address.
2. If you have your private key, you can access the funds for the respective address.
3. If you backup the private key (which is inside your encrypted wallet.dat), you are safe for all future. Or you can backup the wallet.dat to have the same effect.
4. Note that in Spectre, new addresses and new private keys might be generated automatically when receiving transactions to a "stealth" address, so you have to backup those new keys as well. (Not quite sure about this one tbh., the stealth address itself is also associated with some key so it might be enough to backup that one)
5. If your wallet.dat breaks or is incompatible with a future version of the wallet, the private key that is stored inside will be unusable as well, so it is generally a good idea to backup both, the wallet.dat and the key itself.
6. Note that if you export your private key in clear text, you might want to encrypt that one manually.
what is the syntax of "dumpprivkey"?
dumpprivkey -password -address?
because i get the Error: Please enter the wallet passphrase with walletpassphrase first. (code -13)
If you get that error, you have to enter the wallet passphrase with the command 'walletpassphrase' first, like it says. See
https://bitcointalksearch.org/topic/encrypted-wallet-and-dump-priv-key-356943And how do i import my clear text private keys later?
With the 'importprivkey' command. There is also an "import wallet" feature in the GUI that you can use to import a previously backed up wallet.dat. You should probably try that first in the case you need it, the private key is just an additional security.
