NEM (XEM) is known as a dark horse in the crypto community and for good reason. Despite its position as the 14th largest coin by market cap (which used to be a lot higher), very few investors actually know and understand what this cryptocurrency is all about. The coin owes its rankings to an ever increasing interest from Japan. According to Coinmarketcap.com, XEM/JPY pair accounts for more than 40% of its trade volume. Next in line is XEM/BTC at 15% and XEM/KRW at 12.5%.
