There are people in the world who think that fiat and paper currency is the real money, rest all is scam or short term money making opportunity. Due to their lack of high vision thinking they are unable to realize that the future is of digital currency and bitcoin will be the king of those currency. Even with institutions adopting it, they still think it is a scam, strange
I don't think many people consider bitcoin a scam... It's just that most people are used to the old stuff... The same way people used to not trust plastic cards, and even earlier they didn't trust paper money... It was the same with the Internet and cell phone service... I am sure that bitcoin has a good future!
