One noob question.
What is purpose of private key?
Isn't enough to have only wallet.dat and to know the wallet phrase.
You hold private key! You can sent all coin in this wallet to other wallet! You can export private key from wallet.dat! More info! Seaching in this forum!
I am asking, because people are always suggesting to save wallet.dat, but never private key. Is private key already incorporated in wallet.dat?
If wallet.dat is lost, private key is useless? Right?
if you lost wallet.dat, you can download a wallet install it again and import the private key
