Bitcoin puzzle transaction ~32 BTC prize to who solves it

[Arm90]

Hello everyone! I found the key to puzzle 66, but now I have another problem: how to withdraw the funds so that no one can intercept them with a bot? Please repost this message so the creator sees it! Maybe someone can tweet this so that the owners of large pools can respond, whether they can add the transaction to the next block when it is found, without broadcasting it to the network?
Pls, HELP ME!!!!!

i can help you for a reward 15 %, contact me on dm

why PM and not publicly posted here into the thread where it belongs to? I am pretty sure everyone is interested you (or other wizards) can help such key finders

Hi.Because untill he dont withdraw yet,i think it not advisable to post here publicly

[Akito S. M. Hosana]

I think they both have to be full forum members to be contacted. It can't be done with only 2 posts.

Judging by the questions, the person who found the key is a newbie. It will be easy to deceive him in private messages.
And here we gathered mainly those who are in one way or another familiar first-hand with the work of the blockchain, what public keys and private keys are.
And if there is an attempt to deceive, the locals will tell you if something is wrong.

Maybe he didn't find it, he may be lying, we don't know. If he had found it, he would have done hours of research without wasting time, found a safe way to withdraw it and vacated the address. I think he is lying.

He found 66 bit key   but he don't know what to do next ...  yeah, right ... Just another attention seeker.

It's not a game of who is smarter, or how many smart posts someone has; it's about who can guess the puzzle, simple as that, or rather, who has more luck or resources.

Thanks. But why is the speed sometimes 290000 and sometimes 305000?
Sometimes solve in 2 seconds and sometimes in 10 seconds? Strange.

Can you make this same app with gmpy2, I don't trust that  Iceland  ?

You mean in Python?

Code:

Kangaroo is a probabilistic algorithm, it depends which random.seed() you hit at which moment. One is faster and the other is slower. Then it depends on the load of the whole machine.

UPDATE

Guys, here's a new puzzle challenge from the channel https://www.youtube.com/watch?v=LkejrZuQadg, this challenge consists of locating the private key of the address 19L9vivFCPJnAVDsjZ76mF2ZiTLKFUXEpV which is in the same range as puzzle 66, but with a dot , according to the creator, next Friday, he will request a transfer, the objective would be to export the public key on the blockchain and test whether it would be possible for someone to intercept the transfer before it is completed through the RBF, thus removing doubts whether The same thing could happen with puzzle 66, so whoever has the BOTs being heated could do this test with this key. hahahaha.

Anyway, you already know the day, you just need to be more agile than the process on the blockchain, according to the creator, he will place the transaction at the lowest possible rate, precisely to understand if it would be possible for someone to intercept this transaction and withdraw before him, good luck.

Address: 19L9vivFCPJnAVDsjZ76mF2ZiTLKFUXEpV
Range: 20000000000000000:3ffffffffffffffff

complement of the challenge, According to the creator in his new video, the transaction will take place between 1-2am, Brasilia time (UTC-03:00), he said he will try to delay some blocks, to give people time to try to make the transfers using RBF according to the last video https://www.youtube.com/watch?v=Xe1w-AfL6qQ

You are all m*r*ns. Creator of puzzle is well known by ChatGPT.

It is a Polish guy.

Look at this thread: https://bitcointalk.org/index.php?topic=5502994.0

Translate it automatically or just ask ChatGPT who is creator of bitcoin puzzles.

Wow, ChatGPT has a crystal ball for identifying puzzle creators.

But seriously, we're not sure who the creator is. There was just one post from the user "satoshi_rising" in the puzzle thread mentioning increasing rewards, and true to his word, the rewards were increased.

https://bitcointalk.org/index.php?topic=1306983.msg18765941#msg18765941

But that's about it. He's like the Batman of Bitcoin puzzles: he shows up, does something cool, and then vanishes into the night. 🦇

Maybe it's time to recruit Sherlock Holmes!  

[benjaniah]

I wouldn't be surprised if the puzzle creator was also the owner or investor vast.ai.

1. Set up GPU renting service that is very good for BTC puzzle solving, and other stuff too like machine learning etc. Requires not much capital to do this. Some servers, software engineers, etc.
2. Start a btc puzzle which you know requires a massive amount of gpu resources, magnitudes of order than whatever you spent on funding the btc puzzles in the first place
3. Find a bunch of hosts with their own gpu rigs/machines they rent out to people trying to solve these crazy puzzles
4. Charge your hosts 25% commission on the fees they earn from renting out their machines on your platform. Remember, you put up no capital at all for all of the hardware, electricity, storage of these very expensive gpu rigs
5. Laugh all the way to the bank for the next several decades or longer

Wish I could have thought of that

[nomachine]

So, creator, just sitting there, counting the cash as they burn through electricity trying to crack the puzzle. No bricks and mortar, just pixels and circuits.

It was a masterpiece of manipulation, a cybernetic symphony of profit and power.

But hey, if it works, who’s the fool? The guy with the idea or the rest of us who didn’t think of it first? I’m just waiting for the Netflix series on this: 'The Great GPU Heist,' coming soon!

Hello everyone! I found the key to puzzle 66, but now I have another problem: how to withdraw the funds so that no one can intercept them with a bot? Please repost this message so the creator sees it! Maybe someone can tweet this so that the owners of large pools can respond, whether they can add the transaction to the next block when it is found, without broadcasting it to the network?
Pls, HELP ME!!!!!

What happened, you claimed to have found the puzzle? Why haven't you shot it yet?
Because you didn't find it, right?
You are trolling people 😅
Puzzle 66 is very difficult to find, you are not this lucky person either.

[3dmlib]

It will be nice to have contacts of puzzle creator. Then actual solver of 66-puzzle can contact him, proof that he finds private key by saying PK several letters at positions creator requested from him. And creator will help to transfer prize to solver safely bypassing mempool or something.

Oh my God! Whoever thinks I'm just seeking attention is way too full of themselves! Who needs fame from a bunch of idiots? I wasn't addressing you, but rather people like pool operators, software creators, and other professionals, and ultimately, the puzzle creator! I'm ready to provide any evidence to the puzzle creator!
