I would like to trusth mnemonic phrases because it's really convenient to be able to keep your entire Bitcoin wealth in your head by memorizing 12 words, but im still too paranoid to move my cold storage into an Electrum wallet, even after taking all reasonable security measures like doing it in an airgapped computer and so on.
My main worry is key derivation. Someone with the right info could cause wreck you due possible derivation of the seed. Anyone knows what are the exploitable attacks and dangers of mnemonic phrases vs just keeping your good ol wallet.dat in an airgapped computer?
I no longer use wallets that have backup mnemonic phrases but I think it is very easy to use this type of backup to be able to store your personal password in your wallet and to be able to access it anywhere in the world as you like just by remembering a 12/24 word sentence you have no risk in trusting the personal password of your wallet because you knowing the derivation path and your seed you will easily have access to your wallet because the seed is the entropy in human readable form for easy memorization is much easier to memorize an order of words (binary representation) than the seed in hexadecimal format.
But I prefer to save in the wallet.dat than the bitcoin core wallet because it seems more convenient.
