As I am new into bitcoin, may I know how the money supply of bitcoin is controlled since it has no central repository and it is encrypted?
There is no central banking here and that is why this is called as decentralized...meaning there is no one who is empowered to do it for us because it is actually the blockchain technology who makes things going for Bitcoin with the help of the miners located all over the world.
Please make so more research on Bitcoin and its many features and you will realize how beautiful is the distributed ledger technology and this same innovation is now being applied in many industries, organizations and people. Hopefully, you will realize that beauty that blockchain is holding for the use of the humankind.
