A few days ago, Stephen Pair — who is the CEO of cryptocurrency payments provider BitPay — gave an interview to CNBC, where he discussed the future of both cryptocurrencies and cryptocurrency payments. He said that what drives the price of Bitcoin is not its "actual utility" but its future adoption. He added that Bitcoin investors are speculating on the digital currency's future usage and how the technology will be adopted. CNBC further asked Fair about Bitcoin exchange-traded funds (ETFs) and whether their introduction could spark a rally in the price of the cryptocurrency. Fair answered in the affirmative but added that not only could ETF launches drive prices higher but so could greater adoption of digital currencies in general. He believes that the currencies could return to their historic highs if this happens. CNBC then asked Fair about the future use of cryptocurrencies in common daily transactions. Fair said that within 5 years he expects the mass adoption of digital currencies in everyday use. He once thought that it would take 10 years for it to happen, but he now believes that mass adoption will more like happen 3-5 years from now. By mass adoption Fair means that someone could walk into any restaurant or retail establishment and expect that they could buy things there with digital currencies. Fair noted that these types of payments would not just be in Bitcoins or in the wide range of alternative cryptocurrencies available. He said that these payments could also be dollar- or euro-denominated, using monies that have been registered on a blockchain. Hester Peirce, who is a commissioner for the U.S. Securities and Exchange Commission (SEC), has said that approval of a Bitcoin ETF is not necessarily imminent. Earlier this month, Peirce indicated that approval could be either tomorrow or 20 years from now. He further urged those involved with cryptocurrencies not to "hold [their] breath." This past week, the Cambridge Centre for Alternative Finance published a study that indicated that the amount of verifiable digital currency users doubled this year. Bloomberg believes that, because of this, a recovery in prices could eventually occur.
