Saying digital currency Bitcoin struggles with legitimacy is putting it lightly. None the less, it’s something to keep an eye on. Bank of America / Merrill Lynch analysts issued the bank’s first research report on Bitcoin this week, saying the currency has potential to become "a major means of payment for ecommerce.” This was the first report on the currency from a major Wall Street bank. Also, according to tracker Coinmetrics, there are on average 79K daily Bitcoin transactions, and, depending on the days value, those transactions can create a dollar value of over $255M, putting the currency ahead of Western Union.
