Since the beginning of the Bitcoin journey till now, Bitcoin adoption has faced many limitations and challenges. And the biggest challenge is its acceptance. The Bitcoin network is not centralized, which is why many countries around the world have declared Bitcoin illegal (only a handful of countries have legalized it).
As well as the trustworthiness, privacy, awareness, and popularity of Bitcoin use for many people, it has not reached the peak. They consider Bitcoin a fraudulent investment.
 However, behind this lies the abuse of several fraudulent online platforms.Also, lack of adequate education (understanding about wallets, valid transactions, and market conditions) of using Bitcoin hinders its adoption.
