Re: Keyspace and Bitcoin Addresses

Bitcoin on the other hand, has a keyspace that goes from: 1 to n-1 where n = 1.1578 * 10⁷⁷

More precisely, the private key can be any number between 0 and n - 1 inclusive, where n is a constant (n = 1.1578 * 10⁷⁷, slightly less than 2²⁵⁶)

Or 0x1 to to 0xFFFF FFFF FFFF FFFF FFFF FFFF FFFF FFFE BAAE DCE6 AF48 A03B BFD2 5E8C D036 4140

Nearly every 256-bit number is a valid ECDSA private key. Specifically, any 256-bit number from 0x1 to 0xFFFF FFFF FFFF FFFF FFFF FFFF FFFF FFFE BAAE DCE6 AF48 A03B BFD2 5E8C D036 4140 is a valid private key.

and number under 115 bit it is can bruteforce by kangaroo

Take note you need to know the public key if you want to use Kangaroo.
