This is just my honest opinion but I don't think the Dogecoin will still soar, the one that keeps it from going up is because of the tweet of Elon Musk and without the tweet of Elon musk the supporters of Elon and Dogecoin will think that the Dogecoin was neglected by Elon Musk and could result to huge price drop.
When Elon Musk is getting tired of Dogecoin and has got another bigger job, then he will ignore Dogecoin for a while, because it is possible to retweet Dogecoin at a later time, but the impact will not be as big as before, because there are many people who have lost as a result of following Elon Musk's tweets.
