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.

Congratulations on your find! Now go buy some cloud GPU time with your big bounty and crack the next one. Cheesy
