How much BTC should I hold?

I'm constantly hearing about the rise and fall of Bitcoin, and it's starting to get really confusing. I've been considering investing in it, but I'm not sure how much to hold. Should I go all in, or should I spread my investments out? What are the risks involved with holding a large amount of BTC? And how do I factor in things like market volatility and potential future regulations? Could you please provide some guidance on this? I'm really eager to understand more about this complex but potentially lucrative world of cryptocurrency.
