Your explanation is a bit confusing
yes, i have the paper wallet private-key. thats the one i have to use? i used that paperwallet private key to create the watch only wallet. but if i use the same private key in the watch only wallet, nothing happens. because bitcoins are not anymore in the paperwallet, they are in the watch-only wallet.
Importing with a private key would not result in a watch only address, this only happens when you use the master public key. If you used keys from the paper wallet to create the new address, you should be able to recover the funds if you have the xpriv as all child addresses are linked in a HD wallet.
If you swept the funds then, it was sent to a completely new address from the paper wallet and as such keys from it will not work.
yes, i have xpriv key of electrum wallet. that is the wallet with the seed. so thats the key i should use? because the other guy before you said i have to use private key from paper wallet.
i was in that electrum wallet (the one with the seed) and i clicked "new/restore wallet", then i clicked "import btc address or private keys" then i pasted private-key of the paperwallet.
the new wallet address was created and then i clicked "send".
btc is now there.
i noticed if i right click on this new watch-only btc address, menu opens up with option "spend from". if i click it, the green line appears with "coin control active, outputs available"
then, if i want to send i click "pay", set fee, click "send" again, the button "sign" is not active...
where to put keys in and which key? i have all keys. i have xpriv, xpub, i have paper wallet key, i have seed.
