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

I personally began to learn about the cryptocurrency market when I was 17 and came down to the fact that I am now 19 and I'm trying to make money on crypto! Of course at first it is hard, because starting from scratch is not always easy, the main thing is to have the desire and the result will come to you!
