here my monthly salary is about 3,500 Cuban pesos, which is equivalent to 12 dollars approximately
According to Google, it's 145.83 dollars. Why did you divide by 12?
Google also shows the minimum wage is 2100, and the average is 4000 CUP. I guess the cost of living is also a lot lower than most countries.
therefore I would like someone to please advise me on a page where I could work without investments, such as a faucet that is worth it or something that allows me to generate $2 a day because per month it would be almost $60 and as you can see that exceeds by far my salary in my country and it would help me a lot.
How does this work with the trade embargo against Cuba? Even if you have skills you can sell online, as an employer I wouldn't want to risk violating the trade embargo.
a dozen eggs costs 8 or 9$ so it is impossible to live like that
Instead of cloud mining, it sounds like you need some chickens.

I want to clarify something in this forum, because I see that it is something very serious, I am realizing that 90% of the world population is unaware of the reality of Cuba, the government shows exchange rates that are not real, those numbers are only possible. For the foreigner or tourist who is visiting and can buy things in Cuban pesos, in reality for us each USD costs us 250 pesos, therefore do the respective calculations, NOTHING or NO information that the government shows to the world is REAL, just show something beautiful, a mirage, we Cubans live in a parallel universe, I'm not saying that, you can go to any other chat and talk to a Cuban so they can see the harsh reality we go through. Here I leave you a YouTube video about some of the money in my country: the bad thing is that it is in Spanish, I will look for some in English
