Many of the people don't know the whole story behind this. I still wonder what would be a reason for the world's Richest Man Getting Involved with a Meme Cryptocurrency?
Whether you believe it or not, Elon musk is an highly influential figure in cryptospace. Even his one tweet on any crypto or stocks can plunged the markets l. With a reported net worth of $191 billion and the coveted title of world's richest person, coincidentally, Musk is also the owner of Twitter after acquiring it for a more than $44 billion.
Here is the his first tweet of Elon Musk and How he Got involved with Doge Coin.

This was the first time when elon musk added doge coin on his tweet. In which Musk replied the tweet saying, “Dogecoin might be my fav cryptocurrency. It’s pretty cool.”
The response from Musk was to a Twitter poll that declared Musk the winner as the CEO of Dogecoin with 49% of the vote.This was the just the beginning of Musk getting involved in doge coin.
The Second time Musk tweeted about the meme coin on his own is another starting point for Dogecoin. Outside of the response, Musk's first tweet about Dogecoin was on July 17, 2020, when he shared a meme of Dogecoin passing through the global financial system, saying, "It's inevitable."
