Alright, after numerous calculations, I've come to the point where I need someone who is interested in puzzle 66 and capable of counting 48 bits within a few minutes. I have a total of 588 ranges for them to work on, with the opportunity to claim the prize of 6.6 BTC. Alternatively, if the author of the puzzle – the one who created this challenge to test the difficulty of increasing bits – has come across my post, I challenge them to assist me in improving my counting speed. I am confident in my ability to crack puzzle 66 in a matter of days.
you would have to give more information, otherwise nothing can be imagined. Do you need computing power? Does your "partner" have to search a single 48bit range that you provide to him, how do you imagine the billing in case of finding the correct privkey, etc... everything else is just speculation and leaves room for wrong assumptions.
