Banks are concerned that crypto can affect their source of income, they are concern that it will affect their business and people won't want to deposit large amount of money in the banks anymore, remember that Banks are very good at using their customers funds to make more money, especially those amounts in fixed accounts locked for a long period of time.
Crypto is eye opening, as banks as made many people believe that interest way is the way to make money off your deposited amount, the longer you leave the money in your account the more you get get some percentage annually, now we all know it's nonsense, crypto gets people to where they wanted to get to, and faster.
Government is worried about a few different things too, they pretend that they are saving the people from a big bubble but that's not true, there is more to their concerns, they control banks and they have no control over Bitcoin because it's decentralized, Bitcoin also brings better ROI than Real estate and co, meaning many lives can change if done right, the poorer people gets the better for the government.
Yes man, banks use people's money to make their own money, and not only that, their transactions are limited and it can be easily accessible, someone can easily access the amount of money in your account (people like customer service), but in Bitcoin wallets your transactions are not limited and no body can access it if they don't have your seed phrase.
It is true that the banks are worried about Bitcoin from their customers and this is one of the reasons why Bitcoin is not allowed in some countries, and the government, too, are also benefiting from the banks. That's why the government is doing everything possible to stop the adoption of Bitcoin, but since Bitcoin is unstoppable, its awareness is still spreading in society. Bitcoin has given a lot of people another chance in society.
It reminds us that Bitcoin's blockchain technology is decentralized and peer-to-peer. In traditional banking, select staff can examine account details, but data protection rules control these interactions.
Bitcoin promises decentralization and autonomy, but sacrifices personal responsibility. If you lose that seed phrase, you cant recover the funds or call customer assistance. Imagine locking your keys in an indestructible vault.
Yes, financial sovereignty and control are government issues that cause regulatory barriers. Many nations are trying to understand and regulate Bitcoin, not just fight it. As society gains information and insight, Bitcoin opinions may change.
