According to a study conducted by researchers at Imperial College London, cryptocurrency has the potential to become a form of payment that is widely used for decades to come. In their research report entitled "Cryptocurrency: Overcoming Barriers to Trust and Adoption" Professor Imperial College London, William Knottenbelt, and Imperial College Business School Dr. Zeynup Gurguc, argue that cryptocurrency has so far acted as a store of value like a fiat currency.
I think this will soon come true, but people are not really ready to accept the crypto because they are concerned that the appearance of crypto is going to affect their work or income. So I think btc or cryptocurrency needs more time to complete so that people can access it more easily.
