Storing bitcoins without a wallet using only a seed phrase Presently I have some BTC in a custodial wallet which I want to transfer out. I don't want a use a wallet at all. Neither hardware nor software.
If I install Electrum on a live Ubuntu session, create a wallet, transfer BTC to it, note down the seed phrase and terminate the live session, will I still be able to recover my wallet with coins several years from now?
What are the downsides of this method over a cold storage wallet?

What is really important that you note down not only the seed but also the derivation path to your HD wallet. This is necessary for recovering the coins years from now.
