Are you sure that form example there is 10^75 combinations, it seems like a lot  Huh , since all BTC priv. keys - 10^77?
1075 is 1% of 1077.

Bitcoin private keys fall within the following range:
Code:
0000000000000000000000000000000000000000000000000000000000000001
FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFEBAAEDCE6AF48A03BBFD25E8CD0364140

The two keys seoincorporation has used:
Code:

calc

C3... to CB... is around half of all keys starting with C. Keys starting with C are around 1/16th of all keys. 100/16/2 = ~3% of all keys.

So yes, the range shared above is two orders of magnitude lower than the set of all keys.
