That's 3 Trillion key/s. This is crazy. I thought it was easier than that. But anyways If i knew where it is in the 32 ranges, i'd definitely crack it.
But since there's 32 of them, and each range will take one month, it'll impossible to do because of electricity cost.
Your right though. I wish we had an special weird algorithm to somehow get the public key of address 64.

perhaps some people will hopefully invent in the future such programs..
