Now, I don't know his true intentions for shilling this coin but whatever it is, Musk is doing a good work at it.
And talking about Musk himself, I'd say he's quite ambitious and I wouldn't write his ambitions off as being impossible. All of the inventions that were ever made have been thought off has been utterly impossible at some time. If he believes we can have a multi-planetary civilization, the I believe it can happen, although it might take some time.
Isn't funny how Elon Musks shilling of Dogecoin had made a big impact to the crypro and what is more thing about was people are believing him, believing any recommendations or insights he have especially on cryptocurrency.
He really have a lot of charm to attract new investors for Doge, really a major influencer that lift up dogecoins exhange market rate.
If giving a dogecoin to his mother is what he thinks the best mother's day gift he could give to his mother then it isn't bad at all.
