I'm a newb, and curious what happens to bitcoin after they're all mined (considering that it's mostly wealth to absurdly wealthy people mining them now and has been for a while, aside from cloud mining sure but that's not that many is it? IDK), but curious what is the vision 10-15 years down the road it's possible that most the very wealthy people own BTCs? Seeing how more and more transactions are going to be paid via bitcoin (and rich people own most of the companies that GET paid in these transactions) - so I'm curious how it's going to be different?

Thanks!
