so you will have total of 2048 * 12 * 2048 * 11 * 2048 * 10, or 2048^3 * 10 * 11* 12 which eq= 1.1338714e+13

If OP is accurate when he says he doesn't know "the first three" words, then it is only 2048³ possibilities, which is solvable in hours to days, rather than years.

Speaking of Google Account, your wallet has an option to backup the seed phrase encrypted into your Google Drive.

Good thinking. Check this first OP, since it will save you a huge amount of time.

This is my plan that I will make a dictionary of words I know and put it through the program

I have quite a bit of experience with the program, so happy to help out if you get stuck. Just be sure not to share any of your seed words on the forum (or with anybody else, for that matter). If you are certain it is the first three words you are missing, then your tokens file would look something like this:

Code:

^4^Word4
^5^Word5
^6^Word6
^7^Word7
^8^Word8
^9^Word9
^10^Word10
^11^Word11
^12^Word12

Replace the last three lines with the entire BIP39 wordlist three times. This tells btcrecover the 9 words you know in their fixed positions, and then tells it to try every possible word from the wordlist as the first three missing words.
