Especially with the current ramifications of Twitter, plus Elon Musk who continues to show his support for Dogecoin, I think from a profit perspective, Doge can be a good investment if you buy and sell it properly
Without any doubt, i can agree with this as we need to take advantage of any situation without any kind of fomo. 
Whenever Elon Musk made tweets about Dogecoin which pumped it as well as eventually dumped afterwards and surely, many of us made huge profit by taking short postion on degecoin future trading. So, it's a great oppertunity to make profits, but it's not good to hodl dogecoin for long term purpose. 
Not good if you failed to make your sell in the right timing.
It's tough since Doge it's been played a lots of time, each tweets coming from Musk create market movements for this project. There are opportunities if you know how to buy low and sell high. Easy to say but very risky for those who are not capable of holding and waiting for
the pump.
