Elon Musk is a famous man and one of the richest men in the world and very popular.
Popular as Taylor Swift popular ? No! Popular by becoming on of the most hated persona outthere, yeah!
He has slowing become hated by every group out there on different levels, the fudged everything with politics, his management over twitter, and not to mention he had a part in the BTC price crash when Tesla sold part of its Bitcoin investments! Add the whole thing of stopping BTC payments and the drama with the energy consumption and it gets darker and darker.!
Rather than a drive behind the coin Musk is slowly becoming a liability!
Price pump and dump of altcoin is not usually predictable, but for dogecoin, I think one day the price will surely climb to $1-$2.
And where are the 200 billions going to come from?
Also, some really forget one thing, Doge is inflationary, every year it adds 5 billion doge to the supply, at 2$ per coin that's 10 billion every year, or the equivalent for the current market cap every year!
