It seems that someone is doing something very odd here. the above recent transaction https://www.blockchain.com/de/btc/tx/17e4e323cfbc68d7f0071cad09364e8193eedf8fefbcbd8a21b4b65717a4b3d3

Who else other than puzzle owner can spend from theses wallets??
I think that's the reason he can find #65 private key, exposed public key makes it easier  
@arulbero can you tell us how you found it? details on how you used baby-step giant-step algorithm

I think that beyond #85 it will be very difficult to recover the private key, even with 1 TB of RAM (with the Baby-Giant Step algorithm).

With my 32 GB finding the #70 is already a hard task.

But there are other algorithms more suitable that don't need so much ram.
I don't understand thoroughly the algorithm Embarrassed
can you explain in short why the size of RAM matters in this algorithm?
I thought it just generates privkey hex sequentially, finds corresponding pubkey and compares it to target pubkey
