All Services and Transaction fees paid in BCIO Tokens or cryptocurrencies are automatically deducted from the User’s corresponding Wallet, once the Service or the Transaction is executed. If the User does not hold the required number of tokens or coins, the Service will not be provided or the Transaction will not be executed. All Exchange trades are subject to trading fees with the exception for BCIO Tokens 'long' trades.
  • Discounted Trading : Platform fees paid in BCIO Tokens are subject to discounts. Fees will be discounted in various ways. Some will depend on the size of the BCIO Tokens balance held on a User Exchange Wallet. Discount sizes will be determined according to the tier associated to the size of the BCIO Tokens balance. Discount percentages associated with each tier will be decided by Paymium management after the Token Sale following a global survey of BCIO Token holders.
  • Survey Participation Rights : intends to foster a vibrant community. As such, will regularly organize surveys and polls regarding the introduction of new features or the listing of third party tokens. These improvements suggestions will be submitted to the community of BCIO Token holders for consultation purposes. Token holders will thus be able to contribute to’s roadmap. Each User’s voting rights and weight will be proportionate to the number of Tokens held in the User’s Exchange Wallet at the time of the vote. Paymium will retain the right to decide any issue irrespective of the results of any vote.
  • Loyalty & Rewards : BCIO Tokens will be used to incentivize Exchange usage and reward external developers, as well as existing Paymium users and early adopters and supporters.
