Yes, many peoples are choosing bitcoins for their source of income.Earning money through bitcoin is morethan earn on a normal job. so many peoples are leaving job and doing earning bitcoins their own ways.
In my opinion. it is considered one of the best source of extra income while working. I disagree with people leaving their jobs and pursuing bitcoin since having a job tends to develop your skills and abilities more. Bitcoin can be a sideline for them to earn extra money while working but if they are going to leave their jobs for this, then there is the potential of risk losing it. The biggest advantage of bitcoin for me as a student is I earn money while studying. This helps me in my day-to-day expenses while also helping my parents. All of us have different use for bitcoin but in the end, it positively helps us all and brings endless opportunities in the future.
