Ripple's fundamentals, as good as they were before the dec 17' run, have become exponentially stronger through 2018.  Even if they just maintain this pace of RippleNet adoption and companies deciding to use XRP in their payment flows than Metcalfe's Law will take shape before Q3 this year.  Once that happens its an avalanche of growth regardless of the market sentiment.  Buy now people, maybe there will be another month or 3 of low prices but when the train leaves this time its not coming back because of all the utility driven demand of XRP in enterprise client's payment flows.
