He has a great opportunity to do that and has bright hopes if Elon Musk makes his own digital currency, besides Elon Musk is no stranger to his followers, Elon Musk is also very famous among digital currency enthusiasts. that's why he might be more successful if he created his own coin
I don't believe that if he make your own it will be a good hope, because an @elonmusk only uses what he has with a lot of followers and tweets, if it is accepted by his followers then he may be successful, but if he keeps doing that it is certain that it will not continue to be successful, especially by making your own coin.
if he created his own, it's better if its not just a meme coin, maybe a coin for space thing, it will be better, after all he's known for his vision about exploring the space. If it's just a meme coin, there's already so many meme coins out there and maybe many also created within a day, there's no need for more meme coins thats being used for speculative purpose.
By relying on the followers that he have, I don't believe that making coins, especially coin memes, will work well because it could be that he only has a discourse to only do that from looking for profits to be obtained. not to really rely on making their own coins, what was done was only speculative and just happened to be spectacular.
