Bitcoin has been around for 11 years now, with a large ecosystem of exchanges, wallet providers, and apps behind it. There are now many governments recognizing it as legitimate, bringing a large number of investors into it. For just a short amount of time since its inception, I'd say that Bitcoin has achieved extraordinary results. While all of this sounds good, most people still seem to believe that Bitcoin is a scam or not worth their time. For instance, Warren Buffet criticizes Bitcoin telling that it'll become "worthless" over time. It's these negative comments, which make people sceptical about using Bitcoin and cryptocurrencies as serious money for day-to-day payments.
No matter how crypto-enthusiasts try to convince people to believe that Bitcoin is legitimate, everything seems to be the same. I'm starting to wonder why most people have this kind of mentality towards Bitcoin? After all, the pioneer cryptocurrency is being traded at legitimate exchanges. Even some governments have been collecting taxes from Bitcoin. But that hasn't changed people's minds about it. What are your thoughts?

What I have seen so far is that a lot of people that have heard about Bitcoin never take time out to study how it works. Lack of understanding about Bitcoin is their major issue. They will keep assuming in their ignorance until the whole world massively accepts Bitcoin.
