Make a deep and thorough research man! Not all the answers here are complete and detailed. Maybe some give you half of the information that you want but all the info can be searched in the internet. But the moat important thing you need to know is what are the plans of bitcoin and how does it work. If you know these two, you can now start in bitcoin. Its really hard to explain all here but trust me all the information you want to know can be researched.
