We all know how deceitful Elon Musk can be
Exactly. I would not be surprised if it was more an attempt to pump the price of Twitter shares in order to sell afterwards, for example.
We simply don't know what his plans are and expecting that they're indeed related to crypto may be a bit much.
Whatever his plans may be, one thing is certain it will always be to improve his own wealth by taking advantage of what seems to be more trending and useful today. Well, selling Twitter afterwards after increasing its price might also one of his plans, or making dogecoin hype again by the use of Twitter. However, the Twitter committee don't have plans to sell it to Elon. Not that they hate Elon, but they know exactly who Elon is.
