2Babi Ngetot Try calculate not real privat key. Example pkey+1, pkey+2, pkey+3 and etc.

I think , I have little clue about all this bitcoin wallet

First:
 I try use formula x/2^n

Which means  "n"= the key must be start
                    "x" = the private key

Example for key wallet 60= fc07a1825367bbe->to decimal(1135041350219496382)
                                     =1135041350219496382/2^n
                                     =1135041350219496382/576460752303423488
                                     =1.9689828764301732198782612925924695446155965328216552734375

from there maybe 75 or 25 means some thing about next wallet or how much number length need

Let me know if you know some thing

Taking into account probability, you are better off starting the search from the middle of the range and spreading it outwards, however its not always the case.

2 Years ago when I tried to find #54 or #55, I tried it the same way and basically eventually gave up because ETH/ZEC mining was more profitable and when the key was finally found (by LBC if I recall) it was somewhere towards the end of the range, so I would of most likely never found it anyways.

Best would of been some type of pool for this, where if the key is found its equally distributed for all the shares submitted.

I was also wrong on part of my response. The range I stated (1..(2^bit - 2^(bit-1))) is the right cardinality (number of values), but the values given by that range are wrong. The range should be 2^(bit-1) .. 2^bit.

Not completely sure about the math, but I think the percentile for bit 60 using this range is

Ok. For example #60
60 | 0xFC07A1825367BBE | 1Kn5h2qpgw9mWE5jKpk8PP4qvvJ1QVy8su | 1152921504606846975 | 98.5% | 1135041350219496382
1135041350219496382 is how many percents out of full range 1152921504606846975 under your calcs?

Sorry, but I think your math is actually wrong. You are using the range 1..2^bit to calculate the occurrence in the range, but you should be using the range 1..(2^bit - 2^(bit-1)). That would explain why all your results are occurring at > 50% of the range.

IMHO I think it is. Even if the creator of the puzzle didn't do it purposly the software he used most probably was adjusted to generate the most complicated keys within the each given range.

Interesting observation. I wonder if it's related to the method the puzzle creator used to create the keys:

If you do an analisys you will see that all found keys are over 50% of it's range (see here), hence I would say that you can skip the first half and search between 51%-99%.

Hex: 0x2000000000000000 - 0x3FFFFFFFFFFFFFFF
Dec: 2305843009213693952 - 4611686018427387903

Ok. Then You should write checked not check.

What is the full range for 62 bit key?

Is not on this range. Try another one and write here so i try to see if i can find it.

how you sure, that #62 is on this range?

what are those hex keys bro ? and why you post it i don't understand?

It was 20 Million keys per second. But this wasn't this Kangaroo hop program or Bitcrack, this was just with Vanitygen.

Basically the R9 280 and R9 290 both got around 20MH/s, if you had another GPU however in the same rig, it ran at like 15MH/s, and if you had a 3rd GPU it ran at like 10MH/s. It was very buggy also and crashed alot.

Basically had to download the source myself and mod it and probably didn't do a good job. But even 2 years back, or when the 55 key was being solved, it was more profitable to mine ETH or ZEC so I just switched to that.

Bro i advise you to stop wasting you money, for fast bucks ( puzzel ) because  the hashing power which is required to solve one piece is very big, with the money better buy shitcoins, or rennt hash power for mining. But if you know how to use baby step giant step algo just buy amazon server with big amount of ram and go on it  Also feel free to send me tip xD (just kidding)


So how we calculate specific hex range for 64 for example and the possible variatons of 64 is calculated  2^65 - 2^64 = right ?

Edit: Is it have someone who have for example all 22 bit adresses generated and checked for funds ? Maybe have more puzzels or adresses  in these ranges with funds ?




Wow you get with r9 280x 20mh or 20 Milion Keys/s . I dont think you can get only 20mkey/s thats pretty small try to play with -b and -t  - p parameters  try something like this  -b 32 - t 256 -p 1024 and post results. Also my list have only 255 adresses of the puzzel and use -c ( compressed mode) its seems when you put so much adresses the speed drops hard. Also update you amd drivers to last .

Offtopic: Someone who know VHDL here , please tell me is it possible fpga adoption of bitcrack algo ? And if it possible with Xilinx Virtex-7 FPGA VC707  what speed can get ?

Last time I heard Google cloud doesn't like when you use their hardware for anything related to Crypto mining. Amazon AWS doesn't have issues neither does DigitalOcean.

However if you are a new account, you will be limited due to the issues they had in the past with fraud. So for a month or 2 there is a limit of how much servers you can rent. After a few months the limits go away, but you need to be verified because you need to pay by your credit card.

it's just another newbie begging
