PANews reported on March 3rd that blockchain analyst ZachXBT stated today that one of the important indicators to measure the legitimacy of a public chain is whether it has native stablecoin support from major issuers such as Circle, Tether or Paxos. Currently, Cardano (ADA) and XRP Ledger (XRP) have not received support from these stablecoin issuers, and there are no native USDT, USDC or PAX mainstream stablecoins on their chains.
