TOSP coin is only used in the internal process of TOS payment system,not traded in exchanges. Thus, TOSP coin is free from volatility that may occur in transactions. Customers can purchase TOSP coin to use TOS payment system only in designated TOS exchanges and business owners can convert TOSP to TOS coin or to cash only in designated TOS exchanges.
In the real payment market, most of digital coins may be reluctant as payment currency because its value is fluctuated excessively and it takes long time to be approved for complete payment. In T.OS payment system, TOSP (private coin, only for inner circulation) would be used exclusively for fixing the value of payment unit (TOSP not to be dealt in any exchange market), then owners of TOSP can exchange TOSP to TOSC or also in reverse when they want to, with consideration for exchange ratio between TOSC and TOSP (TOSC price is changed, so exchange ratio is changed also between two coins). And Private coin TOSP is suitable for payment only since its processing speed is so fast, it means T.OS payment system is the fittest for digital currency payment, most compliant with market demand!
