I mean, they are so rich, they can start to mine Bitcoin, even if they lose some money they shouldn't care, they are ok with all those money they already have.
Am I wrong?
If you became rich and you are doing the dream life that everyone wants is thanks to Bitcoin, don't let him die.
What is the relation between rich amd mining to improve bitcoin? I think it has no relation in my opinion.
Mining is not improve bitcoin itself, mining just help to confirm the transaction. Mining does not help bitcoin to improve but they do mining because they like to get income from it.
