I'd say there is a 25% chance that XRP is valued higher than BTC by the end of 2019 and I'd say there is a 80-90% chance its valued higher than BTC by 2021.  Proof of work has proven to be insecure (see ETC) and lead to greater centralization.  It's now scary how easy and profitable carrying out a 51% attack on POW coins including BTC.  Also, the XRP ledger is much more decentralized than either BTC or ETH.  Currently Ripple only controls 5% of the validators on the XRP ledger and its getting smaller and smaller.  The fact is that the Lightning Network is a mess and can't offer certainty.  Without this there is zero chance that BTC fulfills its original use case.  On the other hand XRP's ecosystem is expanding rapidly and soon network effects (Metcalfe's Law) will take shape.  It's game over from this point.  Until now crypto has been based completely on speculation and now it will be utility driven demand which drives the price.  XRP is uniquely positioned to solve the $27 TRILLION dollar nostro/vostro problem. 

Oh and for everyone spouting incorrect FUD such as they will create more... please read and educate yourselves.
