The perception of Bitcoin varies among individuals and groups, and it's not accurate to say that the entire world sees it as a scam. However, there are still some people who view it with suspicion due to its association with illicit activities and its decentralized nature, which makes it harder to regulate and control.
That said, there has been a significant shift in the perception of Bitcoin in recent years, with more and more people recognizing its potential as a legitimate asset class and store of value. Large financial institutions and corporations have invested in Bitcoin, and it has gained widespread acceptance as a means of payment in certain industries and regions.
Overall, it's fair to say that the perception of Bitcoin is evolving, and while there may still be some skepticism and lack of interest among some segments of the population, it's increasingly being seen as a legitimate and valuable asset by a growing number of individuals and organizations.
