This sort of change of heart should tell you one thing: The rich have way too much money and love diversifying their assets in an effort to make even more. At this point they must have a lot of clients saying "I heard my friend in the golf club say he made ten million after he bought some dogecoin for under 1 cent a piece using some pocket change". The investment banks are always trying to stay on the right side of the US government, as they've paid many fines and had legal charges against them in the past. Something must be telling them that the US government is likely to regulate this source of funds rather than try to ban it outright, which would devastate the price. I'd totally remove Elon from the equation because he changes his mind more than the tides.
