Almost everything Elon touches turns to gold eventually. I don’t think he will integrate DOGE into the payment system of Twitter though.
I half think Elon just enjoys mild trolling & the narcissistic traits he has make him continue pumping DOGE because the community treats him like a God. He loves the attention.
Well, he is a businessman and he saw opportunity in cryptocurrency particularly in DOGE that's why he is maximizing it.
There was a time though where his tweet that has DOGE has no effect on the coin whatsoever but for an unknown reason, people always link DOGE to Elon Musk especially now that he already got Twitter, many are saying that he might integrate it into the platform.
I don't know how he will integrate DOGE as a payment system or will he ever integrate crypto in the platform, but one thing's for sure. He will continue to keep himself richer with the help of DOGE, and those investors who are following him will lose their money.
Elon is the only businessmen I know that he always includes some weird in what he is doing. I still can't forget the time where he carried a sink while going to his office just after he bought Twitter.
