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?
What is the difference between storing the speed phrase on a paper and storing your private key on a paper a so called paper wallet? As far as I know, a paper wallet is a cold wallet. Or am I wrong? And storing your speedphrase on a paper is a hot wallet cause the actual Private keys are still online?
