These coins were minted prior to any Bitcoin hard forks, therefore the private key stored within not only controls 1 BTC of value, but also 1 BCH (Bitcoin Cash), 1 BTG (Bitcoin Gold), 1 BSV (Bitcoin Satoshi Vision), 1 BTD (Bitcoin Diamond), and 1 of any other current or future hard forks of the Bitcoin blockchain or any of their derivatives. Not to mention, it's a really neat looking coin.
