Can this "Birthday paradox" be used for this option?.

PoB (Paradox of Birthdays)
PoB as an average prvkey distribution (if believe the statistics), the next time (#62) it should not work.
That is, if #61 it was necessary to search in 30% already win, then now the opposite is true - in 60% never win.
And big problem is that it is not stable.
If you were waiting for the moment know it(#61) was Grin

PoB as recurring characters more stable, it + ~50%.

But, see simple calculation
#55 had a ~50% profitability (use VanityGen) compared to the complexity of mining (end 2018, excluding electricity costs).
(if the seeker is unlucky, and he goes through the whole range and finds the key at the end - he will still receive ~50% of the profit, compared to the mining)
#58 had a ~50% profitability (use BitCrack) compared to the complexity of mining.
#59 had a ~50% profitability (use BitCrack) compared to the complexity of mining only if seeker is lucky and 0% if unlucky.
Suppose that BitCrack can work another 2x faster (in theoretically limit), according to information from this and other topics.
Than #60 - last puzzle, where profit was possible (in theory).
Conclusion - the puzzle is no longer profitable! (only if the author increases the award or mining will not be profitable by 4x+more)
Solve the puzzles for fame? Ok, why not?..
But having opened the blockchain, I dont see any glory from #58, except for the simple draining of the address Undecided

you can try and buy hashpower from nicehash

They will not go for it. Because need to add BitCrack as a new algorithm and enter the payment rate. There are lots of programs to calculate, but they do not add them. I think they are simply not profitable. It's sad, because this project that has a great opportunity to consider not useless PoW, but something real.
What about Amazon? 4x-10x expensive vs mining.
What about FPGA? 10x expensive vs gpu, but how many X speedup? (some info 10x, gpus equal, but electricity costs 10x profit)

I agree. difficulty 2^61
the gpu that eats 150 watts and gives 150Mkey/s to go through all the keys 2^61 eats 640000 kilowatt = 19000$(cost 0.03$/kWh)-64000$(0.1$/kWh Grin
