Something is definitely cooking with XEL these days. A stable flow of tweets almost on a daily basis, a new wiki, new tutorials and even a test run on the traveling salesman problem a few days back... I have a really big bag of this project and I don't plan to sell anytime soon as I have really high hopes of what it can achieve in the future!
My suggestion, buy a few thousand coins, hodl and don't look back for the next year. I bet you won't regret it !
