I think calling bitcoin a bubble is a pretty big misconception that derives from misunderstanding how money actually works.
I agree with you. Many of my acquaintances still adhere to it. I also used to think so until I started to delve into and understand the world of cryptocurrencies. I am glad that now I have such an opportunity 
The only reason why people don't trust and believe crypto is they are not fully education regarding Crypto information.
there are too many incidents that were related by crypto that people are getting scammed so although we can't blame them but my point is, authorities should somehow show crypto advantages in order for some people will be brightened on what's the good side of investing Bitcoin or crypto and clearing it out from their minds that it is not a scam nor a fraud.
