Are there Ethereum millionaires?

Excuse me, I'm a bit curious. With the rise of Ethereum and its associated cryptocurrencies, I've been hearing about people making millions through investing in this field. But I'm just a layman, so I don't really know the details. Can you confirm if there are indeed Ethereum millionaires out there? And if so, how did they achieve such remarkable success? Was it pure luck, or did they possess some unique skills or insights that allowed them to make such lucrative investments? I'm just really interested in understanding how the crypto world works, and I think hearing about real-life examples like Ethereum millionaires would greatly assist me in that.
