How much Bitcoin do you need to trade?

I'm curious, could you please elaborate on the ideal amount of Bitcoin one should possess in order to engage in trading activities? Is there a specific threshold or range that's considered optimal for beginners and experienced traders alike? I understand that market conditions and individual risk appetites play a role, but I'm looking for a general guideline to get started. Additionally, how does the quantity of Bitcoin impact trading strategies and potential returns? Thanks in advance for shedding some light on this topic.
