Hi, thanks for your answers.

I used the btcrecover repo to get all public keys from the blockchain (about 300 million lmao) into a database of some sort.
However I haven't yet figured out how I can get btcrecover to use my own lists of seeds to read from, instead of btcrecover trying to do it itself.
Btcrecover seed is fairly simple as it just assumes 4 mistakes in the seedwords. But that is not  my issue here. I want to use BTC recover for its speed, but not the seed generation part.

I have now generated all possible word combinations of 12 words, which is around 479 million combinations.
After checking the checksum of all of these combinations I am down to 30 million valid seeds. I think BTCrecover can check around 10k addresses per second. Would only take an hour to go through if I manage to pull that off.

So I can't simply search in the blockchain with simple commands which addresses have been used when etc? I recon the top100 address site is able to check the balance at least.

What I would love to do is scan through the entire blockchain

If(balance>2 || balance<1):
disregard addresses
If(transactiondate > april2017||transactiondate < january 2017)
disregard addresses
print(whateverisleft)

Then I would probably be able to pinpoint the wallet. There shouldn't be too many wallets that has only been used during some months, haven't been touched for months and still contains 1+ BTC
