This may be a question that bothers me in my heart and mind who thinks that Bitcoin as part of cryptocurrency has deviated from its initial goal which was intended to fight banks
That is a wrong perception in which you are having, bitcoin is never targetted in fighting against banks or governemtn, instead it was discovered to serve as an alternative menas of making payment from the use of fiat currencies, if you think about having privacy and control over your financial economy, then think of bitcoin.
and I think it has now moved towards a commodity project for example (DeFi, NFT and etc) rather than being a legal alternative means of payment
Do you really have to compare a decentralized digital currency to centralized altcoins and projects, i think you have to read on PoW and PoS.
from that question I want to get enlightenment from all members about whether bitcoin and other cryptocurrencies have changed from their original goals? Hopefully this will be material for constructive and enlightening discussion
Nothing has change, you are to read better and make more findings about many things that remains unclear to you concerning bitcoin and the crypto networks.
