Hi,

For the last few days I've been working on a python script that checks the balance of every combinations possible of the missing words in a recovery phrase of mine.

I've learned quite a bit from old topics on bitcointalk as well as here on reddit and now I'm hitting a bottleneck.

Any insight is welcome about this situation:

I miss 3 words from a BIP39 key

I have a python script that does about 2000 checks per second for the last word checksum

When the phrase is valid, it uses electrum to generate xpub key and check if there is balance on the wallet, this takes 1 second

I have about 10PCs that run the script currently

I've done a bit of calculation: 2048×2048×(~100+1) = ~4900 days with 1 machine or ~500 days with 10 machines

100 sec is for the 100 individual balance checks and xpub key generation

1 second is for for ~2000 fast BIP39 checksums

PS: I'll release my program soon so that it helps other people

PS2: any private help offer are welcome, I'm willing to pay 25% of the 2BTCs that are to be recovered someone who would help and teach me how to design a script that would be noticeably faster AND willing to let his code be open source afterward when it'll be published.

Thank you for your time
