You'll Never Guess Which Giant Investment Firm Has Begun Mining Bitcoin and Ethereum

This year may very well go down in the books as the year of the cryptocurrency. After beginning the year with an aggregate market cap of $17.6 billion for all cryptocurrencies combined, the more than 1,100 digital currencies -- as of Sept. 30, 2017 -- accounted for $146.5 billion in market cap. That's a nine-month increase of 732%. Comparatively, the broad-based S&P 500 has taken well over two decades to deliver that sort of return.

Of course, the one-two punch within digital currencies belongs to bitcoin and Ethereum. Bitcoin, the largest cryptocurrency by market cap, is up more than 300% year to date, while Ethereum, the second-largest, has gained more than 3,600% in nine months. Together, bitcoin and Ethereum make up $100 billion of the aforementioned $146.5 billion cryptocurrency market cap.
