Yes, I think so. Bitcoins trend and popularity in the market catch an individual's interest to buy, trade and invest. And I believe that celebrities and other famous individuals owns a huge amount of Bitcoins in Crypto World. Even here in our Country, there's a rumor that the Top 2 Most Wealthy Man here, which is a former Politician (Senator) and a Real State Magnate here, owned a huge amount of Bitcoins and as they say, its the main reason why he is more wealthier. Definitely, owning and using bitcoins has no limits and exemptions in the community, as long as we know exactly how to access the technology and have enough knowledge in Blockchain industry, we can all be owners of Bitcoins.
There will be really a lot of them that are not known to the crypto community. Some prefer to be holding anonymous so the government will not be after them or just for privacy purposes. There may be celebrities that are open to it, but I believe there are many of them that are secretly stashing crypto not only bitcoin but other popular alts like eth or monero.
