It seemed you were the one just waiting to give us an excellent explanation to this unknown mystery. You are really confusing everyone here for idiots, as if you're the only one holding true answers while we're scratching our heads in hopes our IQ goes up. We already know why some prefixes are found more often, it is obvious and normal. This is not your personal class room to teach us your flawed perceptions and wrong theories... why not use your genius in solitude, instead of bugging us? Oh and since you're just on the edge of solving Puzzle 67, I hope you also have a really good strategy to not expose the public key to anyone anywhere, before your TX gets mined.
