I am using bitcrack on RTX 2080 Ti and has speed of 1130 Mkeys/s. I am scanning from last 4 days. Now I am thinking to scan random.

One more participant in the digital lottery Grin

The chances to find the key (randomly) during the priod of 10,000 years with the speed 1130MKey/sec are (1 130 000 * 60 * 60 * 24 * 365 * 10 000) / (2^63) = 0.038636 ≈ 3.8%

For 80 years (like for the whole your life) it just 0.031% [but actually some less because your random could generate the same keys during these 80 years]

For comparison, there are 16,000,000 thunder storms annually, 25,000,000 cloud lightings come to earth. Such lightings kill approximately 55 humans during a year. Considering the average life of 80 years, te chances to be killed by a storm lighting are 1:3000, so it is like 0.033%, which is more than the chances to find a key for #64 with the speed 1130MKey/s for 80 years Shocked

So, do you really expect to be killed by a lighting storm during your life? Oh no, you beleive this will never happen because the chances are very very low.

But why do you beleive to find the key to #64 where the chances for the same period (80 years) are less? - the answer is in our mind which rejects the statistics: positive events are expected to happen (even with very very low chances), but negative events we just not beleive could happened.
