I have came across some questions today while I’m reading some areas of bitcoin, these are the list of my questions.

1. What is the procedure for purchasing and selling Bitcoin, and are there any crucial elements to take into account before beginning?

2. I'd appreciate an explanation of how Bitcoin mining functions and how it maintains the security and reliability of the Bitcoin network.

3. Why is using Bitcoin better than using conventional currencies?

Many thanks to all of you for your explanation.
