I've read some article and it's well written, but i have few suggestion/things to be added :
1. When you recommend centralized wallet such as Coinbase, warn them about disadvantage/risk of using centralized wallet such as no full control over private key and zero anonymity.
2. Don't forget to mention that Bitcoin Core also can be used as full nodes.
3. It would be great if there's an article about places/websites which accept bitcoin.
4. I think use illustration "how it works" might be great when explain how bitcoin works.
