I want to get started with ethereum. Tell me everything.

Hello everyone. I’m Zak, and 16..

I have started saving my money and want to invest. I see ethereum is booming, so I want to learn and buy. After doing some research, I have found meta mask. From my understanding, it is a wallet that I can store my ethereum in. I have found that I can buy through it as well, even under 18. Is this recommended?

I am wondering if it’s a good idea to buy ethereum.

Also, how would I sell it through meta mask? If I buy it through there, can I sell it through there as well? Will the price increase?

Thanks! And please, give me a complete run down and any tips 🙂
