How many people own Ethereum?

Excuse me, I am quite interested in Ethereum and want to know how many people own Ethereum. Could you please tell me about the distribution of Ethereum ownership? Is it possible to get some statistics or data on this? I am also curious about the trend of Ethereum ownership in recent years. Has it been increasing or decreasing? Finally, do you think Ethereum ownership will continue to grow in the future? Thank you very much for your help.
