I am pretty sure it is a scam. They will divorce and will sell off stock at the peak and cash in. I think the same thing is the reason behind the Bezos divorce as well. Purely business.
Most of these marriages are for convenience anyways. Looking at Bill lately and he isn't looking too good but then again his former wife looks like she has more testosterone than him.
Not to mention Bills relationship with Jeffrey Epstein that has been exposed. Who knows what is really going on.
