Are billionaires buying Ethereum?

I've heard rumors that billionaires are snapping up Ethereum. Is there any truth to this? Are they really investing in this cryptocurrency? If so, why? Is Ethereum really a worthwhile investment, or is this just a fad? And if billionaires are indeed buying Ethereum, what does that mean for the rest of us? Should we also consider investing in it? Or is it too risky? I'm really curious to know your thoughts on this matter.
