Low Tech Low Cost secure seed phrase solution - Removes any need for expensive proprietary hardware wallets for secure long term Bitcoin storage.

You have 12 (or 24) words that must be kept secret secure and accessible.

You select a book and find where each of those twelve words first occur within the books main text.

You encode where the words are found eg- p3w49 etc.

You write down the encoded location of the words.

This text can now be safely saved on your digital devices, on paper, steel plates or on your wall.

There is no great need to conceal it...although probably discretion would be the best approach.

Nobody can decode the seed phrase unless they know the text they need to be decoded.

Happy New Year.
