there is no other way but to invest in hardware, so give up
You forgot the plain simple luck. The majority here relies purely on that alone and nothing else.

We should make a list of scanned prefixes and upload them to the web daily, for example to google doc.

Support it. Everyone has their own GPU power, the pools have very long ranges, and can they be trusted.
You scan locally without sharing your final answer to the pool. Does not matter if you trust the pool or not, you keep the answer to yourself.
How do you think the pool can steal it?

Why overcomplicate things? You are talking about a pool. You can just join one.

I have tested 3 apps, BitCrack 625MKeys/s, VanitySearch-BitCrack 1024MKeys/s but the problem is it gets hang multiple times in a day and forced to restart my PC, and KeyHunt-Cuda 945MKeys/s with these settings (KeyHunt-Cuda.exe -t 0 -g --gpui 0 --gpux 950,256 -m address --coin BTC...)
Does not hang for me running days. Something is wrong with your system.
Could be the high load, maybe the power supply can't handle it or just the general overheating. I would try to run it with opened case maybe or add some extra air flow.

Если прямо совсем холодный, то я бы ещё посоветовал посмотреть на ColdCard MK4.

While everything is ultimately binary, hexadecimal provides a balance of compactness, readability, analyzability, and compatibility with cryptographic tools, making it a logical and standard choice for such projects.
This is my point exactly. It's just for human readability and has nothing to do with repeating characters/digits when properly randomized.

In theory, everything is simple, yes and no. You just need to create your own random generator, with all these exceptions, then no additional verification is needed. The generator is not needed numeric, but directly in hex
The random data is binary anyway. Why don't you use octal instead of hex? Or binary directly?

Imagine how much more quickly these keys would be solved if we teamed up resources/knowledge instead of constantly arguing about petty bs. It's embarrassing.
At least, you can join a pool to team up using brute-force.

I based my statements on what you yourself said. The keyspace of Puzzle 71 is not particularly small either, but according to your claim, bots are capable of accessing the private key in a very short time simply by having the public key. Now, considering that Puzzle 135 has a larger keyspace—which I acknowledge—with the speed you attribute to these bots, don’t you think there has been ample time since the creation of these puzzles for the private key of Puzzle 135 to be discovered and the funds to be transferred? It appears that some of these claims may be misleading. Could it be that you are the same individual who took the Puzzle 69 funds from the person who found it?
The keyspace of 71 is small enough to get the private key within short period of time.
But 135 is much larger space. No, I don't think there is enough time to get the private key of 135 within similar period of time.
Your claim about "there has been ample time since the creation of these puzzles for the private key of Puzzle 135 to be discovered" is incorrect.
It seems like you did not read my message above. Please do.

It does not matter if i'm the same individual or not. The space for 135 is significantly larger compared to 71. My individuality would not make it smaller.

What you're saying makes no sense. Because if there were a bot that could access the private key of Puzzle 71 in just a few seconds by revealing its public key and steal the funds, then surely it could access the private key of Puzzle 135 in just a few minutes as well! And you're claiming this is due to the public key of Puzzle 135 being exposed? Your claim is completely baseless and biased. It seems your only intent is to deceive and mislead other users. If you really found a puzzle's private key, you can go ahead and use your own method to send your transaction—but don’t try to lay that trap for us again
I think you are missing the point on how big numbers work. Puzzle 135 is way-way-way bigger space to search through compared to 71.
It's not double, it's several quintillions more. No way you could find it in "a few minutes".

In my opinion, no website should be used to send transactions at all. The best way to send a secure transaction is through the Electrum wallet, so the transaction won't be stolen and there's no need to worry about the delivery.
Electrum will use public pool to submit your transaction. And because it's public, everyone can see before it's confirmed and so everyone can steal if the private key uses low entropy like in this case.
And no, disabling RBF won't do anything at all.

This is why it's suggested to use private pool to submit your TX. It's not visible until mined/confirmed.

Is it possible to limit maximum fee somehow?
The only limit to the maximum fee is the sending amount itself.

"In response to your question, I have conducted studies on the elliptic curve that allow me to simplify some key encryption calculations. One of these is the calculation of the compressed address of the private key. To compute this, we first determine the decimal representation of the key and then multiply the result by 256. This gives us the decimal number of the private key for the compressed address we are looking for."

It's even easier: you just shift 8 bits to the left (or add "00" at the end when in HEX).

Trezor Safe уже более поздняя модель, которая устранила старый недостаток. Я писал про старый Trezor One, там нет SE элемента.
Всё верно. Потому я и писал про Safe серию, у которых есть защищённое хранилище. Даже принципиальные схемы открыты, софт -- тем более.

Я до трезора так и не добрался, кошелек не поддерживает некоторые экосистемы, которые мне нужны.
У меня кроме Trezor есть и другие. Покрывают все мои хотелки. Не обязательно ограничивать себя только одним устройством если требования такие.

I think the electricity company makes payment variations so that the consumer doesn't notice it too much. That way I know that I'll pay more or less within that amount, whether the AC is on or not, or whether or not an extra 3060 is on Smiley that must be it.  My whole life has been like this... I'm 54 years old now and the electricity is always within those values, whether it's cold or hot. Im in Portugal..but i beleave is different country to country Smiley
You mean when they average monthly payments based on your full year's consumption? Yes, some of them do. In this case it's harder to track what you use even though you pay the full price anyway, right.

At the end of the month, electricity always costs between $80 and $150. And when summer comes, it can reach $200 with the AC on in the room. I can made pay
Got it. I guess you don't load your PC all the way up if you pay between 80 and 150 only. If you do, that's like one more AC running all the time.

true...but it won't affect me at all whether I spend 100 watts a day or 270 watts a day. At the end of the month it won't be very significant. Of course, for those who invest heavily in this, I believe they need to do a lot of calculations to know if it will be worth it or not Smiley
When you crunch 24/7 using 3060, that's a way more than 270 Watts per day.
Just the 3060 alone draws about 150-200 Watts, that's not including CPU, RAM, Mobo, Monitor, etc. If you use 3060 for 24 hours (a day), that's like 4000 Watts*h per day without including other components. 15 times more than "270 Watts per day".
If you don't pay for your electricity or have a flat fee, that's different.

Resources? My PC has been on 24 hours a day every year long before I knew about this puzzle. So for me the costs are what they already were Smiley
You should not forget that your PC's power consumption heavily depends on the task it's doing. It can vary a lot from a few Watts to several hundreds.
