There are a lot of ways to be able to earn bitcoins. There are signature campaigns, mining, trading, and doing tasks from websites that offer you btc in return.
According to me, the lack of knowledge and the lack of interest in the world of crypto currency can be the possible reasons of losing money and not making anything good even being there in crypto currency. You really need to make a self-analysis and you need to figure out the actual problem. This will give you a fair idea of what the problem is actually and correcting that will help you in making more money.
you need to do an analysis not of your work, but of your own business, because perhaps you are doing the wrong job. It is necessary to initially choose the field of activity that will allow you to receive the maximum Bitcoin. Even if you have no knowledge, then in parallel with the work you need to learn.
