Bitcoin will help you to earn money, it helped a lot of people to earn money by just using technology. In my opinion bitcoin cannot help you to be rich, but it can help you to earn more money than normal work. Bitcoin is not a stable career it is because you are depending on the time when bitcoin is on a low price for you to buy some and waiting for the time that bitcoin will increase its price. It would take time for you to earn and sell bitcoin which means also that it would take time for you to earn money.
