You petition is good and I believe it's born out of good reasoning, but I doubt if it's going to make any impact at all on Elon musk, this is if at all he even sees it, don't forget we are talking about the world's richest man here, he will probably be too busy to see this petition except some how, the petition become very big and trending in the entire crypto space and on Twitter too, then and then alone is there a guarantee he might see it.
So right now I did just say you should relax, Elon won't be hurting the market, but those who blindly put their life savings in dogecoin are the ones who will be hurting themselves, Elon only tweeted about dogecoin, he never asked or forced any one to invest in it, people out of their own free will invested, when things go south, I personally expect them to count their losses and don't blame anyone.
