Why USDT is not available for direct purchase?

Unfortunately, the exchange platform does not offer direct purchases of USDT. However, you can effortlessly swap any cryptocurrency to USDT with a 0.5% swap fee. Moreover, it is possible to send or receive USDT to and from an external wallet. Please note that the fee for these transactions depends on the network used and is beyond Fasset's control. Therefore, when sending USDT to an external wallet, be sure to select the correct network to avoid any inconvenience.
