The coin is very interesting and promising, the acquaintance took 6000 coins, a year ago, now he is shocked that so the coin has grown in price. That means a good investment!

XRB is the most worthy investment altcoin at the moment because I am sure the XRB will soon be listed on Binance and I am keeping a lot of XRB from 6 months ago. I hope the XRB could soon reach $ 50 in 2018 because big investors are very interested in this altcoin
