Hey, as you know already from the title, I'm new to Bitcoin, I would like you to help me by telling, where to buy, when to buy, where to sell, when to sell, things like that.
Important: I'm 17 years old, some methods may not work if I don't have 18, and that's what I have noticed.
I hope you can help me get started.

Edit: Thank you guys, your information is helping a lot, I already have a wallet, feel free to help me
