Man, I really don't understand you. What is your goal in selling this script if it really works!?
WHY DONT YOU OPEN ALL KEYS from 61 -> whatever you can, if it takes you less time then others?
0.025 BTC price for script? Mate, if you open even #61 address you will cover ~24 buyers. ))
Why do you spend your time for prooving that your script does work? For the same time you could open #74 address and get the bounty!!!
Where is the logic???
If you sell your script to several people they will open all possible addresses (until the time required will be within an adequate range) in a days and then your scipt will just remain in a history of cracking.....
Because it only works on the addresses with spend transactions: 65, 70, 75, 80, 85, etc. and all of these have been opened up to #100. #105 will take a bit of effort to open so instead of running it all that time just sell it to others. Kind of makes sense at this point.
What is your expected time for #105?
I was using 4x Tesla V100 for it. Here is a table with expected times:
|------+-------------------+-------------------|
| bits | 4x V100 | 100x V100 |
|------+-------------------+-------------------|
| 100 | 2d 19:52:51 | 02:42:54 |
| 105 | 16 days | 15:21:34 |
| 110 | 90 days | 3d 14:53:14 |
| 115 | 1 year 147 days | 20 days |
| 120 | 7 years 341 days | 116 days |
| 125 | 44 years 323 days | 1 year 290 days |
| 130 | 253 years | 10 years 57 days |
| 135 | 1,436 years | 57 years 166 days |
| 140 | 8,125 years | 325 years |
| 145 | 45,964 years | 1,838 years |
| 150 | 260,011 years | 10,400 years |
| 155 | 1,470,848 years | 58,833 years |
| 160 | 8,320,376 years | 332,815 years |
|------+-------------------+-------------------|
Looks like a "world record" would be 120 bits.
[Edited after half day]- according to an earlier promise - I updated the list of addresses in the main post (along with the size of the range). In addition, I've also added links to useful tools for unit conversion and key checking. Greetings!
