1\ #CryptoEngine collection is a mix between a human heart and cold mechanical heart. Sometimes we have both of them. This is a paired token, a black heart will be gifted to the owner of the gold one. 2\ This heart has a very special value to me because I made this for my friend. He is currently fighting a great battle for his life. I want to do everything I can to help him and his family. Which is why everything I get from this sale will go directly to my friend family 3\ Additionally, a second mechanical heart will be gifted to the owner of the gold, this is symbolic for me because I poured my heart and soul in this project so, who collect this piece and helps my friend I give you my heart! *a black heart can only be gifted for all times
