For a newbie member in bitcoin industry, its true that it will not be easy for us to catch up at once what bitcoin really all about. it is because its very hard to understand
but for a determined people, confusion has no space to Him/her everything will be easy to adopt and to understand it quickly.
You don't need to understand it to use it. That's also true for fiat currencies based upon a national debt, which is pretty much all of them. All that a newbie user really needs to know is how to get them, how to keep them, and how to spend them. In reality, you can either learn how the system works, and then trust it for the mathematics; or you can learn to trust it for the same reason that you trust fiat currencies, simply because they continue to work.
