I did not yet try to restore backup of wallet.dat. its in my home pc.
I dumped privkey and imported it here, then I also imported privkeys of the purchased syscoins. nothing appears.
That's why mate. When you send coins it sends your change to a new address from the keypool, which is part of your original wallet.dat.
but I dumped privkey of my wallet and imported it to new wallet.dat.
but I dumped the privkey of the wallet in "receive" tab. does that mean the change is sent to "" or 0 or 1 address? i should have dumpprivkey "" ?
