I can copy/paste 200 private keys into Electrum and it "pauses" for about 10-15 seconds... and then after clicking next it takes another 30 seconds to have a think while it creates the wallet and generates the address matching the private keys...

For the record, I have a Core i5-3570K, 8 GB RAM, Windows 10 64bit... OS and Electrum on an SSD...

I reckon I could probably crank through the addresses of ~20 seeds per hour without even really rushing... so you probably have 10+ hours worth of copy/paste to check all the seeds (assuming your "23" word seed generates a similar number of valid seeds as mine)

EDIT: In case anyone is interested, the (very) unpolished script is here: https://github.com/HardCorePawn/btcMisc/

usage:
Code:
generate_mnemonic_keys.py word1 word2 word3 ... wordN-1

Where N is a standard mnemonic length... ie. 12, 18, 24. So this means you should enter 11, 17 or 23 words!

NOTES:
- You NEED the wordlist directory and English.txt file
- Script will hunt for valid seeds, and once found, will generate 100 receive addresses/keys and 100 change addresses/keys and dump them into keys_XXX.txt file(s), one for each seed.
- Script is only looking for ONE missing word
- Script only looks for missing word from position2 to positionN-1 (ie. it does not look for a missing First or Last word)
- Script is only using BIP44 derivation path and only looks for Account 0 addresses/keys

Thanks mocacinno   LoyceV   HCP,
for all the information,  I am sure a lot flew over my head, but Im learning.
but things seem more plausible now.

Will defiantly check script, and play around,  when I get home

Basic maths would suggest that there are 22 positions (as you think not the first or last word)... and 2025 word possibilities (most wallets don't re-use seed words).

The seed on one of my eight nano’s did pick for me a seed with the same word used twice, sequentially.

So it’s a rare possibility.
