lately, I found most articles the Bitcoin can make the economy more freedom and it will replace traditional financial institutions like banks etc. but what I have seen in the last few years is almost all of the cryptocurrency controlled by the crypto exchange and some related industries about blockchain, so this what is called freedom (most people only think they can print money easily and quickly) ?
of course if the future bitcoin continues to be developed and becomes perfect, then the paper currency or coins will be replaced, why? because bitcoin has a supply and is temporarily limited to paper money, metal can be produced without restrictions.
