Hello I'm pretty new to the Bitcoin scene. I decided to get involved after realizing that I could mine without worries of an electricity bill. So my question is for a person I my situation just starting and not having an excess of money what hardware/software would I need to get set up. I browsed multiple sites online and they all point to having some expensive hardware specifically designed for mining bitcoins. My limitation at this point is funds. So how would I start out and work my way up?  Thank you for your time and consideration.
