“Google Trends shows that searches for the term ‘bitcoin’ stayed pretty steady throughout the month until October 28, when it more than trippled almost overnight. And a chart of Wikipedia pageviews mirrors that trend—slow and steady until the very end of last month, when the number of people visiting the site’s bitcoin entry leaped from 18,000 to 113,274—an appreciable 700 percent increase. Somewhat interestingly, the charts show that although bitcoin’s value has been climbing relatively steadily, its hyper-trendiness just kicked in this past week. That might be a clue that people’s interest in the crytocurrency was piqued after a good long run on the market. Or it might not.”
