The issue with DOGE is its low value
It's not an issue to doge, consider it's supply is never ending so it's value is just normal and low. Base on that thing it managed to be at the top 50 of the coin market cap.
I think ardor in the next year will show steady growth. I'm waiting for the price of$ 50 by the winter of 2018
It's current price is $1.6 and you are asking for $50 which is too much growth though it's possible to happen. This coin looks good and I haven't did some research about it.
