Bitcoin Adult is cryptocurrency focused to become an ultimate payment solution in adult entertainment industry. Dramatically faster, cheaper, and more scalable from Bitcoin in its current form, Bitcoin Adult is designed to provide a scalable and sustainable alternative to Bitcoin. Using Proof of Stake algorithm with masternode validators, instead of Proof of Work we solve problems like high network fees, slow transaction times and massive energy consumption. Visible and traceable transactions leaves users vulnerable as anyone has the ability to see all associated transactions and balances. To solve this problem, we implemented zerocoin protocol which enables each transaction to be private for entertainers and consumers anonymity. Adult services have always had problems with payments via credit cards, banks and PayPal payments, with services being denied and accounts closed. That being said, based on restrictions and financial discrimination in this industry, additional problem for adult performers are webcam sites that take up to 50 percent of a performers earnings. Therefore, most consumers and performers in adult entertainment industry are looking for a new payment system that will allows users to send anonymous and instant payments with lowest fees.
