It seems that banks have no intention of becoming like Bitcoin. After all, banks will always be centralized. They might adopt the underlying technology, blockchain, and could even derive various benefits from Bitcoin. But, they certainly will not allow their own capabilities to be usurped by Bitcoin, in its capacity as a currency.
That is why, in some countries, governments have banned Bitcoin as a currency. They believe it would disrupt the nation's financial system, including the banks themselves. We know exactly who controls the banks globally, yet, at the same time, they also stand to gain from such developments.
but with this news looks like banks cannot hold their horses but want to adopt bitcoin as probably they see some potential for huge profit why can't they just leave bitcoin alone.?
I don't think they will, because they would lose even more trust and prestige. People would naturally prefer Bitcoin or other cryptocurrencies instead. Since they cannot profit directly from crypto, those behind the banks, who still want to extract profit from their banking systems would be unable to do so. Furthermore, they would lose their ability to exert control over people worldwide through centralized banking.
