Today most companies, business, individuals etc no don't know much about Bitcoin, their interest is just for profits and making money,
They have no interest on the future of the coin how to keep it decentralised, how to fulfill the real purpose of the coin.
In the nearest future if everyone decide to only investment to make money, Bitcoin will become so volatile because at that point it will be all about speculation/emotions vs big players, it will just be a game of manipulation and speculation there for the reducing the interest of developers, and reducing adoption. The profits we all look up to might not be there anymore. Government will find it more easier to control, there by increasing the risk of centralisation.
So it will be a good Idea to shear to users that there is more to it than just profits, and keeping the coin decentralised should be priority
Use Bitcoin don't just invest and hold, if there are more users globally it will be hard for the coin to be centralised, there have to be transaction everyday, payments, subscription, transfers etc. tell more people about Bitcoin, empower developers to protect it simplicity and openness, and with this Bitcoin survives
Bitcoin cannot be controlled by any individual or any government because it is a decentralised asset and it's decentralised is the main reason bitcoin hasn't crashed. If the government can't control bitcoin I don't think they can manipulate it either. Nobody can't manipulate what is beyond their reached. people don't have to keep bitcoin decentralised, it is already decentralised . The major reason why people are investing in bitcoin is profit driven and I believe no person would invest in bitcoin other than that. The big companies who are investing in bitcoin aren't foolish,they invested in bitcoin because they are seeking alternative of generating profits for their various companies and they wouldn't invest in bitcoin if they don't have clue about it
