Now that we have a glimpse that you're likely not the brightest candle on the cake, it's pretty much clear that there's no feasible way to find the HD wallet's master extended private key or even the mnemonic recovery words which encode the wallet's main secret very likely random entropy.

Bitcoin's cryptography has been safe for 16y and will be safe for longer. HD wallets are a few years younger and are safe too, unless the wallet owner is plain stupid and can't secure the mnemonic recovery words properly.

You may want to hop to https://learnmeabitcoin.com and learn a bit about Bitcoin before you talk about stuff you have no or little clue about. As many others with their questionable contributions here, it's just noise to this thread.


Puzzle #135 is the next available with a public key exposed. It's not impossible to solve, it only depends how much resources you're willing to throw at it. But you wrote "practically impossible", and well that might be the case when the resources to solve it cost you more than you could gain from finding a solution and successfully withdrawing it.

To withdraw puzzle #135 you don't need to use slipstream.mara.com because bots can't find a solution any fast. This is the case for all remaining pending puzzles with exposed public keys unless some new magic is invented which frankly I don't see. And please, don't start some blabbering about quantum computers when your knowledge about those comes basically from public clickbait news.

Of course, for puzzles #71+ you need slipstream.mara.com or similar non-public, non-fraudulent miner's mempool to withdraw without fear to loose your puzzle prize to bots.
