Doge coin is a meme coin created for fun and I don't really believe in Doge's "tothemoon", most likely this coin one day can make ×3-×4 for a short term but no more...
Dogecoin has got a strong and supportive community which will make it live for long term due to its quick transaction confirmation and low transaction fees. However, due to the lack of innovation and developments on the team, i doubt Dogecoin can make any huge price rise to the moon. Perhaps McAfee intends to create another FOMO due to his large influence.
