People are not stupid, they are scared of smth new to try. When i heard about bitcoin first time on my head was things like "lame, don't work, etc."
people dont like doing new things and are easily maniupalted by the media in the actions that they take. People are unwilling to learn new knowledge by themselves and would rather be led to beleive false fake info.
I think it's reasonable when you first hear about new things. then you're going to try to protect yourself. but if you want to find out what it bitcoin. I'm sure you will be convinced with bitcoin and immediately try it.
people are so lazy to find out what it bitcoin. so they have not been able to join and use bitcoin
