The future of money looks very different in
The combined market value of all cryptocurrencies in circulation reached US$170 billion by the end of August 2017, 850% higher than at the beginning of the year, according to CoinMarketCap, a leading cryptocoin prices and market capitalisation tracker website. It is no surprise that this kind of growth sparked much hand-wringing among regulators and central banks, who are still undecided whether cryptocurrencies should be classified as a commodity, an asset or a form of currency.
That might seem like an odd discussion to be having. But one of the basic functions of currency is to facilitate transactions in a timely manner. And to protect the security of the blockchain (the technology behind cryptocurrencies such as Bitcoin), the processing of Bitcoin transactions is sometimes very slow.
