While Bitcoin did return to the limelight in 2016 after a lull, it is only a year later that it grabbed the entire world's attention as its price soared and there were some measures of acceptance into the mainstream asset market. A clone of the currency, named bitcoin cash, also emerged in August 2017.The price of Bitcoin hit a record high of $20,0089 on December 17, 2017, according to CoinMarketCap. Amid repeated calls for caution, the price of Bitcoin plummeted nearly 15 percent on December 22 to below $13,000, just days after futures trading in the cryptocurrency began. Chicago exchanges CME Group and CBOE Global Markets launched futures trading in Bitcoin in December. In mid-January 2018, the price of Bitcoin fell below $10,000 for a few days amid a broad sell-off in the cryptocurrency market over concerns of strict regulation being planned in South Korea and China.
