If I memorize the seed generated when wallet was created, would that be considered a brain wallet? Can you give other examples of brain wallets?
Also how can an attacker use a password to attack my wallet seed??? I thought passwords were used to protect (encrypt) private keys? If I have not exposed my private keys, how can my wallet be attacked by randomly guessing passwords?
Yes, if you memorize the seed it becomes a brainwallet, as per its definition on the
Bitcoin WikiA password can be used to attack a wallet seed when you have that seed on an online computer, protected by that same password...
