It depends on who do you introduce bitcoin to, and the way how you introduced bitcoin to the. Not all people is tech savvy, I've introduced bitcoin into some of my friends and only a couple of the really got involved in crypto currency. Even I who really believes in crypto was skeptical on it when it was first introduced by my brother.
in my case my friend introduced me to bitcoin and i like it i read articles about cryptocurrencies and i joined this forum to explore and learn more but when i introduced it to my other friend they show no interest in it and i gave up because i can't force them to understand it
That is because they are close minded about bitcoin, if a person is open enough to listen and understand bitcoin then they will be able to understand is little by little but if they are close minded then no matter how simple you explain it to them then they won't understand it. Bitcoin for me isn't as hard to understand it just depends on the person on how they see it.
