We would like to point out that ParamountDax Exchange uses the highest level of security and compliance for their digital assets, the advanced security provided by the company that holds Bitgo funds, with insurance on funds up to 100 million in case of losses due to system violations. Most of the funds of the ParamountDax company including the PRDX tokens are kept inside a large wallet, which contains every single wallet generated by users, and this means that the "holders" are less than those who they really are, this happens because the blockchain identifies them as a single wallet.
In the near future when users move PRDX to other exchanges or to personal wallets then the number of "Holders" will be destined to increase.
