Thanks, I finally understood a little bit better. Great simple explanation

I´d love to start learning about mining to earn money, but I have ZERO knowledge about computers, do you think it´s possible?
Sorry to be the one to give you the bad news, but nowadays, you cannot make money mining BTC unless:
- you pay less than 6-7 cents/Kwu for your power
- you live in a country with low import duties
- you have a budget of a couple thousand dollar
- you have a naturally cool place, shelves, good power circuits, extra PSU's where a lot of noise isn't a problem
- you have a basic understanding about how Bitcoin works
- you have some technical skills (cooling, networking,...)
- you're willing to invest a lot of time doing research, making plans, setting everything up, monitoring,...
If you had to answer "no" for one of the points above, i would not start mining BTC if i were you...
If you try mining altcoins, some of the above restraints might not be necessary... I've heared about people making profit mining altcoins while paying a lot more for their power, or starting from a much lower budget (for example)
