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

Bitcoin isn't just your ordinary currency, it is different from fiat. There's a lot of information and articles about Bitcoin in the internet so maybe you should start there. Next is getting some Bitcoin. There's a lot of basic ways to earn it, from faucet, buying from exchanges, or engaging in some of the services and activities here. But remember, never trust anyone in the internet specially when it comes to Bitcoin transactions because there's a lot of scams now a days.
