I don't think so but to my mind the answer is obvious because the number of scams has increased. It is difficult to define who is who. That's why a lot of people think that it is necessary to be careful with everyone
Yes,and today alot of fakes news spreading in social media and sometimes bitcoin is the topic.And because this people dont have any idea about bitcoin they believe on what they hear or see and sometimes they watch.So that they dont want to involved in cryptocurrency.
Well i think that some of them are not actually or never heard about bitcoin and what are the benefits you might gain that`s why they think that bitcoin is a scam and because of having so many reports in social media as what you have said and also it might be seen at the news today.
