As of right now, there is no way to buy Pmon directly with fiat currency on Binance. In order to purchase Pmon, you will first need to buy another cryptocurrency that is listed on Binance using fiat currency, and then trade that cryptocurrency for Pmon. At the time of writing, the only cryptocurrencies that are listed on Binance and can be bought with fiat currency are Bitcoin (BTC), Ethereum (ETH), Tether (USDT), and Binance Coin (BNB). So if you want to buy Pmon on Binance, you will first need to buy one of those four cryptocurrencies with fiat currency, and then trade it for Pmon. Keep in mind that when you make a trade on Binance, you will be charged a small trading fee. The trading fee is calculated as a percentage of the total trade value, and it varies depending on which trading pair you are using.
For example, the trading fee for BTC/Pmon is 0.1%, so if you were to buy 1 Pmon for 1 BTC, you would pay a 0.1% trading fee, or 0.001 BTC.
