Seizing this opportunity I think the profits will come very quickly but not sustainable, those experienced enough in the market are always confident about the decisions they make. Looking at the fomo people follow, groups, yt channels, social networks spreading it to the masses,... unfortunately the truth is that only a few succeed with the news. Personally, I'm not a fan of surprises, but I know what to do with them, I'll take some profits and continue to observe the subsequent reaction of the market. With this market, there are indeed many opportunities for everyone, but first do your research and start with small goals.
Buying when the hype has already reached a certain point is definitely not a wise move, especially in scenarios like these where the hype is for a very short period of time, and only those who get in early can profit from the market movements caused by the hype. So, the people who are buying doge now when the hype is just about to end, are most likely going to lose value for their investments.
Though the logo is still there, the hype won't stay very long, and the price has already started to drop I think, so it would only be wise to just be a speculator at the moment and stay away from trading the token.
Buying doge in any time is definitely a wise move. Just on the off chance that maybe elon would say or tweet or do something about doge that could take it higher is not a smart reason to invest into doge, that would mean that you would have to wait for him to do something and he eventually did but we all know that people got lucky with this one, it wasn't an expected move.
So all in all, nobody should buy dogecoin right now, and nobody should do it after a while neither, and nobody should have done it previously neither. If people stop caring about Elon and his tweets, I would guess that price would also stagnate a lot as well. It just doesn't make sense to purchase something like this, looks like a silly move.
