In late March 2019 Bit-Z was ranked second by the U.S. dollar value of its traded volume according to CoinMarketCap, an online industry statistics reporting service. Its trading volume reporting has attracted attention because it uses the so-called "transaction fee mining" model for payment of exchange fees. According to its white paper, Bit-Z's BZ coin is created when a user pays its fees in cryptocurrency and the exchange reimburses the fee with BZ, thus incenting valueless trading in order to pay fees which are reimbursed.
