2. You have to buy bitcoin to see how it really works. i dont mean you have to buy bitcoin constantly
You can practice using Bitcoin without buying it by using Bitcoin's testnet. It's even better because you don't risk any real money.
Also, this statement is just redundant, because of course almost every Bitcoin enthusiast owns Bitcoin, and if they don't they must have some reason.
4. Democratizing bitcoin means telling people about the technology and how it can change the world. When i bought my first bitcoin in 2017 i can remember how i was excited and telling people around me about this wonderful technology
Democratizing means making something more democratic. What you are talking about is spreading the word about Bitcoin. It's a good thing to do, but it's also dangerous, because criminals can target Bitcoin users, so be careful who you are talking with, and never tell how many coins you have.
