But having said that, the thing is that other investors are getting it wrong investing in Doge only cause of Elon's interest in it, without intensive research, nor examining their long term sustainability; if you don't find Dogecoin to be a 'great project', then forget about Elon Musk and don't invest in it, DYOR, and pick coins that are in tandem with your interest.
indeed at that time Dogecoin had risen and now it has actually decreased significantly,
I don't know what will happen in the future, I hope the price of Dogecoin can go up
It's similar to a TV commercial in which if the most famous celebrity is the one advertising it, people will buy it because of that celebrity, well what is the hype then people will jump in even if they don't need it in their life.In the case of Doge, it is not a bad thing if they bought the coin during Elon's hype. It is also a smart move to jump in and then sell it, rather than holding it because it was a bad move. Similarly to Bitcoin, when Tesla recognized it as a payment method, it was later removed by Elon Musk.
