What is the minimum buy amount on Binance?

Could you please clarify the minimum buy amount required on the Binance platform? Is there a specific threshold or does it vary depending on the cryptocurrency being traded? I'm particularly interested in understanding the minimum investment required for novice traders to get started on Binance. Additionally, is there a way to check the minimum buy amount for different cryptocurrencies directly on the Binance platform or through their customer support channels? Thank you for your assistance in answering this question.
