How many Bitcoin private keys exist?For comparison, there are 2^256 possible private keys for the traditional 256-bit Bitcoin private keys, which is roughly 10^77, only a few orders of magnitude away from the number of atoms in the Universe, estimated to be around 10^80. That's one thousand quadrillion vigintillion! A serious number of zeroes.
I want to know the total number of possible private keys for the traditional 256-bit Bitcoin. I heard it's related to the concept of 2^256 and is an extremely large number, close to the estimated number of atoms in the Universe.
