Bitcoin did a lot of growing up in 2017, but there was one trade this week that could go a long way toward stabilizing the market for the cryptocurrency and further establish its credibility in mainstream finance.

Sure, the meteoric rise in bitcoin prices has everyone debating whether it's one of history biggest bubbles, but just look at all the accomplishments that have put it on the cusp of joining the global financial system. LedgerX opened the first U.S. Commodity Futures Trading Commission-approved clearinghouse for cryptocurrencies in October, and began trading in swaps and options. Cboe Global Markets and CME Group have started trading in bitcoin futures. The New York Stock Exchange, Intercontinental Exchange -- and no doubt others -- plan to offer exchange-traded funds based on bitcoin futures.
