I have asked at least 20 people individually about what they understand with bitcoin.  So surprising to find out that all they know is that bitcoin is scam.  It only leads me to the conclusion that it really needs to study and make research to something you didn't know before giving your point of view to something.  The fact that what they only see in TV news and social media are the bad side of bitcoin due to people using it for scams.  If people would just do their research about it, they would reconsider that bitcoin is not that bad at all.
