Hi all, I have been researching on digital mining but having a hard time understanding it. I have asked someone and the best answer I got is its a project that when you sign up they give you an equation to solve and rewards you with coins. That all I know about it. Can somebody here please explain to me how exactly it works. I also have a few questions in mind. 1. Is bitcoin and litecoin similar if not same thing? 2. What do you get out of it? 3. Is it like web hosting? 4. Is it part of the mining industry? Thanks for reading.
