In my opinion, most people who have a lot of bitcoin are hiding their identities, because the anonymous nature of bitcoin is an option for many people in the world or maybe other people who have many famous bitcoin celebrities.
that's right, I agree with you because not nearly everyone does not want to show that they have bitcoin or are involved in cryptocurrency, everyone has their own reasons and for me in a country that has not received bitcoin then I do not expose that I have bitcoin.
Many celebrities do not hide that they own Bitcoin and other cryptocurrencies. For instance, Paris Hilton, Mike Tyson, Ashton Kutcher, Donald Glover state that they have already made money on the crypto.
