What is the minimum amount to buy TRX?

Could you please clarify for me, what is the smallest sum of money that I would need to invest in order to purchase TRX? I'm interested in getting started with cryptocurrency trading and TRX seems like a promising option. However, I'm not sure about the entry point in terms of the minimum purchase amount. Could you guide me on this? Also, would you recommend starting small or should I invest a larger amount to see better returns? It's a bit confusing for me to decide as I'm still learning about the crypto market. Thank you for your assistance.
