I think the majority of educational people has heard about bitcoin, but problem is most of the time is promoting as a way to money not as a solution to a real problem. That's the reason why most crypto people are at the space just for money in first place and the funny thing, they want other people to join in order to bring more money to the space so the price can moon and they become rich by selling their bitcoin at high price to those newcomers. Because the focus is on making money, Some outsiders see bitcoin as a scam and bubble that will have a sad ending.
