Crypto is still at its early adoption so there's no reason for banks to feel threatened. Yes, crypto adoption is increasing but majority of the people are still relying on banks with their finances. Some banks are open and have positive view towards crypto. And in fact, some banks are adopting as well and slowly becoming crypto friendly for their users who are also into crypto. Tho there are instances where banks tend to be more cautious when it's involved in crypto. Their relationship is like having to co-exist together, now that the technology is getting more advanced. It's like, both of them are there but it doesn't mean that they have to be "close" or have that happily ever after situation. Crypto is crypto, bank is bank. Some situations may get them involved with each other but not every time.
Banks have been under threat for a very long time, and the ETF and other activities will make bitcoin even more unique. Bitcoin can act as a currency and an asset, which is something that fait cannot do. If fait implements such kind of futures, it could potentially destroy the entire financial system, and we live in a new era where practically everything is evolving. even though they are a part of the financial system, I am aware that the most of them will use bitcoin and pretend to be against it. The entire potential of bitcoin has not yet been shown, but even in the event that it is adopted, we can all agree that it won't have an impact on our banking system because bitcoin is similar to government-issued money.
The government is the only entity opposing bitcoin, and we all know what they want: the ability to control the cryptocurrency and begin levying taxes on it. I don't even think banks have a problem with bitcoin. And when bitcoin first gained popularity, many banks had no problems with it until the government began to restrict it. After that, though, the rest realized they had no control over the matter, and in my country, the ban was lifted, allowing you to do whatever you wanted with your bitcoin at the bank. yet even before then, it is rare to hear of someone being detained for using Bitcoin alone.
Both banks and bitcoin depend on each other to function; without one, the other is impossible. I'm confident that the bank will receive a certain percentage from traders, as that is what the government has requested and is currently receiving. Furthermore, the fact that bitcoin is now more widely viewed as an investment than a medium of exchange makes things better.
