Using the 3-digit PIN, there are 1,000 unique chains available. Owner’s PIN will correspond to one of these. Each of these unique chains have been randomly generated.
With a 100-card Chaindeck, there are 2.4x10^247 (2^100 x 4^100 x 100! / 8) possible chains. Note that the calculation includes a division by 8 because a chained deck oriented one way vs another is still the same chain. For example, grabbing a deck and flipping it does not create a new chain.
There are 8x10^67 (52!) possible ways to shuffle a 52-card deck of cards.
There are 10^77 (256-bit) possible bitcoin private keys.
