    With this feature, the client and other users can seamlessly transfer the amount to their bank accounts. The users can transfer the money from Bitcoin and Ethereum points into their bank accounts in the form of money.

  • Chat Options

    An intrinsic feature that helps the users whenever they are stuck. The chat feature was integrated to have a one-on-one conversation between users and the customer support team to get quick answers to their doubts.

  • My Profile

    This section was crafted for every user to create their own profile. This profile will allow them to add necessary personal information, add card details, add cryptocurrency, bank account details, and a profile picture. The section will also have a usage policy and verification & limitations so that the users do not exploit the information but rather keep their data secure and safe.
