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.
Maybe next ten years it can be used widely, but i don't think we can guarantee bitcoin will be like that in future and maybe in future many great crypto currency created that can be rival bitcoin.
Yes, maybe bitcoin will be in the mainstream but due to technology and the fast rising of cryptocurrencies, maybe also some other crypto will be on the mainstream. Thats our MAYBE. If you are in bitcoin that maybe is for you if you are in other crypto the other maybe is for you. If you are in both maybe you are sucure. If you are not in bitcoin and crypto maybe you are lost. Maybe its better to join now.
