Most people know that having organizations, governments, or anyone else trying to own more of the bitcoin supply is not good for bitcoin or us. But the problem is we don't seem to have any way to prevent it so instead we should ignore the things we can't solve and learn to adapt to things.
Bitcoin is a decentralized blockchain which is censorship resistant too. There is no existing dictator to prohibit or set up a max cap of bitcoin for one investor. It is decentralized and opened for all investors if they have belief in Bitcoin and have capital for investment, welcome them to Bitcoin market.
They will have to buy existing bitcoin from current investors, traders or have to accumulate new released bitcoin from future Bitcoin block subsidy. Challenge will be bigger with time when Bitcoin adoption grows more, and there will be more new investors, bigger new demand on Bitcoin.
As new investors, they must feel happy when there are current investors who shake hands and sell their coins on the market. With less supply if there are less sellers and less bitcoin for sales, they will have to buy more expensive bitcoin.
