PRIVATE KEY

Private key is often dubbed as quindecillion. In a mathematical study, quindecillion is a number that denotes the number or is called a cardinal number (0 [zero], 1 [one], 2 [two], 3 [three] and so on), not the number of states stages or levels, such as first , second, third and so on.

The principal number followed by 48 zeros (short range) or 90 zeros (long range). Just as the millions have 6 zeros and trillion numbers have 12 zeros. So just imagine how many combination keys can be generated in a private key. That's the answer, why private key can be unique one la
