In 2015, the number of merchants accepting bitcoin exceeded 100,000. Instead of 2–3% typically imposed by credit card processors, merchants accepting bitcoins often pay fees under 2%, down to 0%. Firms that accepted payments in bitcoin as of December 2014 included PayPal, Microsoft, Dell, and Newegg. In 2017 bitcoin's acceptance among major online retailers included three out of the top 500 online merchants, down from five in 2016. Reasons for this fall include high transaction fees due to bitcoin's scalability issues, long transaction times and a rise in value making consumers unwilling to spend it. In November 2017 PwC accepted bitcoin at its Hong Kong office in exchange for providing advisory services to local companies who are specialists in blockchain technology and cryptocurrencies, the first time any Big Four accounting firm accepted the cryptocurrency as payment.
