You only earn $12 in a month? I'm curious what your job is, but I think the amount is very small and if you already have a wife and children it will definitely be difficult to survive. Maybe you need to look for a better job considering you are already 28 years old
There is a signature campaign on this forum and I get paid $1 for each post. Not much but not bad either. But for higher ranks, they will be paid more. I don't expect you to be here just to make money as this is a discussion forum. If you have the ability, maybe you can start as a freelancer. I once joined several freelancer sites but am now retired because I am busy working offline.
I work as a doctor or I used to, not anymore but the salary, as you can see, is very little, plus we don't even have the basic medications to even provide good care and with such a bad working condition in my work sphere I won't work because it's in my hands. I have lives, not cars or objects, they are people, so that you have a reference, a dozen eggs costs 8 or 9$ so it is impossible to live like that and first I would need to generate some amount of money to then be able to invest it in something online, well not even Not even my money can be used on the internet, they only really let us enter dollars, you can imagine why.... interests
I mean you worked as a doctor you said. Why you didn't pursue your profession as a doctor? TBH, I'm a bit curious. I don't want to generalize all, but what I know is that, doctors always had a high salary. Anyway, are you an expert doctor? You have 2 choices. Continue your profession, and work in an hospital, or be an online doctor. You have license right? Use your profession to earn money, and don't expect too much on faucets. Find a way to use it. Maximize your time, and don't use it on faucets.
I just hope that you will not do what most of the newbies are doing here - joining bounty campaigns. :X
Where did you look for that information? If I won 150 dollars, believe me I would be happy, put here the link of the pages where you looked for the information, a Cuban doctor in another country does win, in Cuba friend, no, that information about the salary is false, in fact the Minimum wage in Cuba is about 2,100 Cuban pesos, which is even less.
