OP didn't mention BNB, which is worth for an investment rather than having Dogecoin. I'd never think if that is not accepted in India or it was just the OP's watchlist
Anyway, we have done with Elon, Dogecoin will become dead soon, only just to happens that the market still on the bullish side that is why traders are enjoyed using Doge for trading. If this will be over, and I don't know if Dogecoin holders were still able to keep it on their hands or they will sell and dump it.
I would say doge is the least worthy of a good long term investment, it skyrocketed all due to meme status it had with people and Elon Musk pumping it, nothing more. We need it to go more and more higher to keep everyone satisfied and it can't do that, it was already at the top for a while around 4th rank or so and that was it, you can't expect it to go beyond bitcoin or something, which is why doge already saw its peak and not going to see that again.
Others, the btc, eth, bnb type of high level ones are fine, those are things that we can all agree to say it is great, and I do not think that people would argue against that, it made us all money and they are all very good coins that has a very good reason to be high, not just joking or memes but actual use case where people need to keep buying to make it go up. That is why they are at the top, and very good investment for long term.
I also see the same thing with DOGE, Elon musk and his followers are the only ones making DOGE pump but recently we can see that Elon's tweets aren't much effective as before. Maybe due to the losses of other people's last crash that makes his old followers doubt about his manipulation. Doge isn't really the best for the long term, there are many good mainstream tokens to choose from so why would people go to DOGE for long-term investment. BTC is always the go-to in investment and long-term hold but if we talk about alternatives, ETH, BNB, and other fundamentally strong token are pretty good to hold.
