I invested in Xaurum a while back, but took a real hit when it got delisted from Bittrex and it's gone downhill ever since. Still holding, but would like to see it listed on more exchanges, the volume is so low at the moment. Not as confident as I was when I bought it, but not really any point selling now, so will see where it goes over the coming months. They occasionally announce updates via their social media channels, but nothing that has caused any real reactions in the market yet. Hoping that it starts to creep back up throughout the year.
