Everyone knows cryptocurrency is all about safety and anonymity. Our opinion is that every person has rights to hide his personal information. Considering this, this utility project Candy Thieves fit perfectly to help people in such needs.

Holding the ERC20 token $CDTHV will bring the users with many services to help hide their identity, this includes: Proxy Service, Number Renting, Account Marketplace, and Antidetect Browser. Please visit our website for in-depth explanations on those features.
