Currently, I don't have a job as a retired person, so, I was wondering if mining can get me some money to support our family daily sustenance. Could you give me my best option, and what would be the cost of setting up mining rig? Thank you.
Right now mining cannot offer what you ask because mining is not that much profitable to sustain your monthly expenses of your family.
Unless you have some capital set aside and you can build a few mining rigs , have money for electricity to pay for a few months you can give it a try but I don't suggest this second option.Better find something else, internet is full of possibilities and since you are retired you have a lot of free time to search.
