I think that there will be no repeated excitement. The second time, nobody will not react to the words of Elon Musk as at first time
A tweet left by Elon Musk on April 1
https://twitter.com/elonmusk/status/1377567762919292938 the pro that "SpaceX is going to put a literal Dogecoin on the literal moon" led to a 31% Dogecoin pump. So Elon Musk followers still react to his posts, despite the fact that he was dedicated to April Fools Day
Dogecoin? Sure. Bitcoin? I do not think so. I mean sure tesla buying 1.5 billion dollars worth of bitcoin was a big deal and I would assume anything like that again would increase the price. But I am not sure if he would be really increasing a ton of stuff for people if he just tweeted something like "bitcoin is awesome" or whatever, I don't know what is required to make it happen but I think he can't just write something cool about bitcoin and get it increase like crazy.
Doge on the other hand is a small coin, there is nothing that would make him really change a lot, it's going to be just doge and since it is easy he would tweet and it will skyrocket that's going to be the case for a long time. Obviously doge and bitcoin are different things, I think he could even pump ethereum if he wants and that's second biggest coin, but not bitcoin.
