I don't think doge will get overtaken by any of the new coins, well they will overtake buti don't think they will kill it. If its lasted this long is obviously proven its worth and it still hasa huge following . I might even buy back in just in case.
yes you are right may be it will take some more time to raise, but currency it does not look like that doge can show a remarkable increase in its price, as there is very little volume in it.
