I always read about public keys,private keys and speedphrases that you need to store them in a paper wallet or hardware wallet. The only thing I ever stored are the passphrases (those 12 or 24 words) I get from metamask or other wallet provider in the beginning of creating a wallet. Is this enough when I write them down and secure them?
