It is apparently impossible for anyone to know everything about Bitcoin as a result of it's persistent changes in exploration
Including developments, this issues has address over time here from my observations, that no can actually be satisfied trying to know everything about Bitcoin because the growth and development will keep evolving over time and for that anyone trying to get everything knowledge before investing will never invest in Bitcoin, if those that has been in to Bitcoin investment for long now can not know everything I wonder such possibility for those that has not started because getting started will make anyone to gain experience and knowledge but not everything about Bitcoin, all we need is the basic concept and knowledge to get started while leaning other things with the passage of time.
