Hotcoin currently supports purchasing USDT with 47 fiat currencies, primarily including CNY, USD, HKD, JPY, GBP, and EUR. On the app’s home page, tap [Deposit], select [C2C Buy], then use the search in the top-right corner to choose the fiat currency you want to pay with and proceed to buy.
Friendly reminder: USDT purchased via fiat requires a 24-hour wait before it can be sold in C2C or withdrawn on-chain; however, it can be used immediately for spot, futures, Earn, and other trades.
This is a “whole-account withdrawal restriction,” not a limit on a single asset. The restriction period is calculated from the execution time of the last C2C fiat purchase.
If multiple fiat USDT purchases are made on the same day, the last execution time will apply, and withdrawals will be disabled for 24 hours from that time.
