private key to mnemotic seed wordlist (electrum compatible)

[Kryptowerk]

Hi decrypt experts,

my goal is to generate a seed for Elctrum that contains a private key that is already known.
So is there any way, if you have ONE private key, to find a seed for electrum that contains this one specific private key?

Thank you,

I don't think so, otherwise people would be able to steal your money.

Just create a new empty wallet, and TRANSACT your coins from wallet A to wallet B. Always avoid exporting private keys, seeds or anything that could compromise your money. So simply transact the coins after the fork (I assume this is due the fork) to another wallet, then export these keys, then dump segwit2x or whatever.

You'll need a brute-force attack. With 2048 possible words, and 12 words in total, that gives roughly 5*10³⁹ possibilities. You won't find it.
As far as I know, having 1 derived private key doesn't help you find back the word seed, it wouldn't be as secure if that would be possible.

Alright, thanks guys. The reason I was asking: I have a physical bitcoin I would like to use as cold storage and it would be nice to memorize the priv key. However i realised it would be probably much easier to just momorize the seed such as used for Electrum.

I assume a physical Bitcoin has a random private key, instead of derived from a seed. So this wouldn't work anyway.

With memorizing anything, just bare in mind one thing: life can go in unpredictable ways and there is always a possibility that you might forget a word from the seed. It's safer to keep it stored somewhere safe, preferably on more than one place.
