1. Another indicator of bitcoin’s momentum is the number of mainstream businesses that accept it. In 2014, Microsoft MSFT -0.84% , PayPal, Dell, and Dish Network DISH 2.24% , among many others, announced they would accept bitcoin as payment for a range of products. Those companies joined companies such as Target (which accepts Gyft, which can be purchased with bitcoin), Overstock.com, and WordPress. Even the publisher of Fortune, Time Inc. TIME -0.40% ,began accepting the cryptocurrency for magazine subscriptions. Yahoo YHOO -1.02% also added bitcoin to its Yahoo Finance tracking site last year, lending the currency additional legitimacy, and Google Finance GOOG -1.30% quickly followed suit. “Adoption of bitcoin is becoming more commonplace, and we feel it is relevant to our industry and to our users,” a Yahoo spokesperson told CoinDesk. Don’t be at all surprised if Yahoo soon goes even bigger on bitcoin—whether by acquiring a bitcoin startup or some other announcement—as part of CEO Marissa Mayer’s ongoing effort to make the stalling search giant more hip.
