Had you invested 1,000 US dollars in Bitcoin in 2013, you'd have over 18,000 US dollars now. According to Michael Mollet with CBOE Global Markets, people love investing in Bitcoin as it’s decentralized cryptocurrency. It's not controlled by any central government and it can be traded across currencies in the same way that the fiat currencies can. However, Bitcoin futures started trading late Sunday on the financial market giant Chicago Mercantile Exchange Group (CME), following its debut on the CBOE, marking another step in Bitcoin's path toward mainstream investing.
