Very it seems that Doge its growth played the most the first from all coins. And now will sleep for a very long time. So I think it will be even later the opportunity to buy again these old coins.

Not for now if you buy DOGE, because my experience this year bought at 35 Satoshi prices.
Now the Doge price is at 58 satoshi, if there is a possibility of going down it might be better to wait to buy at 35 satoshi.
Yes, the price was much lower that year,this is the trend on all coins almost.Waiting for takeoff on New year,and nothing will prevent.
I now buy and I save up, all the same profit will be.
