The New York Stock Exchange has announced that it plans to make available a Bitcoin index on the NYSE, giving further legitimacy to the crypto-currency.

From today the NYSE will feature the Bitcoin index in the NYSE Global Index. It will also be temporarily available publicly on the NYSE’s website.

The index is calculated once a day, to four decimals and will be published within 2 hours of 4PM U.K. time (11am Eastern).

NYSE Group President Thomas Farley said that “Bitcoin values are quickly becoming a data point that our customers want to follow as they consider transacting, trading or investing with this emerging asset class.”

The Bitcoin index pulls data from Coinbase, in which the NYSE happens to have made a minor investment earlier this year.
