My  opinion is XRP
For XRP, with the xRapid and untill Q3 of 2018, their revenue increased to double in compare to Q2.They got a good team with many project, currently 2 finance company just joined their RippleNet, one from malaysia and the other from England. Can  say that  the XRP  network  is grow up every day now. I'm thinking about hold more xrp for next year.
