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
You are dreaming. Here we have a thread where gmaxwell and other inveterate cryptocurrency developers point out that XRB in inherently insecure. https://bitcointalk.org/index.php?topic=1219264 These problems cannot be ignored and no serious exchange can list a coin like this (suicide).
