Well... Actually I'm Doge hodler/user since 2014. So I may be biased. But honestly, there is no reason for Dogecoin not to be around 1$ level. if BTC is Gold and LTC is silver, then Doge can and should be copper :P.
This coin is fast, relatively cheap, has no problems with scaling, you can buy and sell it almost everywhere (I recommend shapeshift.io) and should be used for everyday shopping (snacks, coffee, tipping etc).

One drawback I know isn't a drawback really.
They say there are to many coins floating around, but you know, at this moment even 5 billion new coins produced annually doesn't change much (in terms of %).
When Chinese New Year of the Doge ticks in February, Asia will buy it all anyway :)
