DOGE is fun and will continue up for a bit, but I think it's decline will begin in the next year as people get bored of it.

Ripple will have a big year as more gateways come on board, volumes increase and client is improved.  More gateways will also allow for small scale remittance to start up, showing some of it's real potential.  Along with greater trading of bitcoin and alt coins.  Hard to beat instant transactions and relatively user friendly trading platform.  Ripple has also finally come up with a good way to distribute XRP with the BOINC giveaway.  It has a solid 'mining' type process that actually puts computing power to good use.
