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
The original purpose of creating BTC wasn't for it to 'fight' banks, BTC was created to be an alternative currency to fiat, but one that is censorship resistant, permissionless and decentralized.
from that question I want to get enlightenment from all members about whether bitcoin and other cryptocurrencies have changed from their original goals?
Kind of, but it was expected, BTC does not have one use case, so people will decide how they want to use their BTC, and neither you or i has the right to tell them what to do with their coins. BTC has really developed, and there was no way it was going to stay exactly as Satoshi created it, there have been a lot of improvements and people will use it how they like.
