Saiph Savage, University of West Virginia: Cross-border transactions and e-commerce are the best solutions for using cryptocurrencies

According to the financial community, Saiph Savage, a professor of finance at West Virginia University and a visiting professor at the computer science department at Carnegie Mellon University, said in an interview that whether governments should regulate the use of cryptocurrencies remains a debate. Cross-border transactions and e-commerce are the best ways to use cryptocurrencies. The advantage of cryptocurrency is instant settlement, because the design and implementation of blockchain technology can eliminate third parties and reduce the process of cross-border transactions. However, the volatility of cryptocurrencies is too high, trading time is long, not suitable for daily consumption (but still faster than traditional cross-border transactions), there is still a long way to go to popularize. Due to anonymity, cryptocurrencies are also used for money laundering or illegal transactions. This is the main reason why governments have called for a ban on cryptocurrencies.
