As a newbie in crypto, I will also feel that "what is this?" "How do people earn from this?" because bitcoin it is not introduced by just whoever that you come along the road or your teacher or your parents. It is something that you should really give time to study or understand with. In fact when I was starting my journey in this crypto world this just blew my mind on how this thing work and grew without noting by many.
This is something that you need to dig in, but it is not hard to understand, dig in because for you to lighten up your so much questions, because there will be more questions after a question.
Initially when it is new you will need to get knowledge and understand it. Just like when you get new job, we need to understand the working and the process of that organization and new softwares etc in same way we need to understand the bitcoin and its functioning. What are the different ways on this form or through crypto how we can make money and grow rich?
Some people mindset is that bitcoin is an ordinary thing someone can adventure into without proper research, cryptoccurrency is very broad to study but we can take a measure to study it step by step in order to understand the major of concepts of cryptoccurrencies especially bitcoin. Working in crypto it needs attention or engagement.
