This known facts since the existence of Bitcoin because Satoshi wants a decentralized financial world which obviously an anti bank movement. Its too late know for bank to lessen the popularity of Bitcoin it was being adopt already by many counties including US. Banks is starting to adapt on it and using the blockchain to match Bitcoin with there CBDC that use private blockchain.
Banks will never beat Bitcoin since people will choose decentralized over centralized in long term perspective.
True, something like this hasn't happened just once or twice in Bitcoin history, so my view is that this isn't something that should surprise me, as they usually do FUD at bad times to spread investors' fear for their money.
I came across this news on CNBC where standard chartered bank claims that bitcoin will reach 5000$. Being a bank, this can be their wish and not a reality. Banks do not want bitcoin to become popular and therefore they spread this negative information so people panic sell and do not adopt bitcoin.

Banks are just another body of government. Due to the decentralised nature of Bitcoins, no government can control Bitcoin, that is they cannot impose tax on it. This is the reason for which the government is against Bitcoins, and not making it as a legal tender. They advising all the banks to thoroughly moderate all the transactions associated with cryptocurrencies.
Yes, banks and governments are one unit in co-opting global and local finance, of course, this is clearly their plan to scare us bitcoin believers, my analysis after they scared the crypto market, they will declare a CBDC shortly future as an alternative transaction tool as opposed to Bitcoin.
But my view is when people use CBDC as a legal means of transaction it will make people easier to access Bitcoin than FIAT money, why do I think that? because many people have made Bitcoin an investment asset, of course Bitcoin is easier to access with CBDC, In the end, Banks and governments will admit it.
"And maybe the goal of satoshi will be closer to making Bitcoin a non-central transaction tool when everyone understands what and why bitcoin was created"
