What is the minimum amount to trade Bitcoin?

Good day, I'm curious about the minimum amount required to engage in Bitcoin trading. As an aspiring investor in this digital asset, I'd like to understand the entry-level threshold. Can you please clarify the minimum amount that is typically needed to start trading Bitcoin, and if there are any factors that might influence this amount? Additionally, are there any specific platforms or exchanges that have lower minimums for beginners? Thank you for your insights.
