I think you are only looking at the downside of the possibility that's can happen but I would like to remind you that fiat wasn't actually the first currency in use from the first period of time and still humans adapted to it and have since used it despite the disadvantages that it first pose during its adoption in the world.

Change is a constant thing in life and thats what no one can fight although am not sure of whether bitcoin can take over the world but if eventually it does then I think the impact of positivity will be more than disadvantages.

Defining domination of the entire world will help us a lot. Bitcoin still cannot have scalability for all daily transactions. In fact, any decentralized system will fail in this and therefore second layer solutions and a lot of development will be needed before we reach this stage, not to mention that this will require For years until we reach trillions of dollars in market capacity, which may happen after 10 years, 20 years or more.
Therefore, when that time comes and technology develops, many things will change about our current world, and therefore we cannot rely on the values ​​that exist now to predict the future.

Has this stop the new and innovative ways of doing things from taking over the old fashion way. The world is constantly evolving, we have to move with the flow and learn new skills so we can stay employable. The bankers just have to learn new skills and they'll be good.


Developing and underdeveloped countries are those that'll benefit more from the adoption of Bitcoin. The lack of understanding can easily be addressed by enlightenment program been organized across the country so this isn't a problem and when the benefits of Bitcoin adoption are been understood by them they won't see Bitcoin as a curse but a blessing.


People don't trust the bank because they know the banks are controlled by the government but Bitcoin isn't control by the government but puts the power over your finances in your hands. It'll be easier for people's that distrust the banks to trust Bitcoin because they'll see the difference between the two currencies.

Any major change brings both new opportunities and devastation to those who represent whatever the change is replacing. That's why it's important to have measures that will ensure that people who are suddenly suffering from the change receive support to adapt to the new normal. But let's see the specific points the op raised.
1. Banks won't necessarily be miserable, they'd just have to rebrand and provide services of crypto holding. Some people will always choose centralized services because they don't want the responsibility of securing their own funds, making sure they can restore access if they lose it, etc.
2. Some people would probably lose jobs, but that's where unemployment benefits come in, and perhaps special programs to retrain people who were employed in the industries that are no longer relevant would be required.
3. Actually, there doesn't seem to be a correlation between the strength of the economy and attitude toward Bitcoin. Some strong economies embrace Bitcoin, some weak economies are against it, but the opposite is also true.
4. Those who don't trust the banks would be delighted to know that they can hold their own cryptos in non-custodial wallets, and they don't have to trust anyone but themselves this way.

As the technology advances over time, there's a lot of people that are left behind with the knowledge causes for them can't keep up and lose the benefits they could get like for example for the adoption of Bitcoin. For sure in a long run people could still manage to learn how crypto industry works by exploring it in the meantime. Still there's a number of people that are confused about the system of Bitcoin, so employment rate would be affected as well the economy of a country. While for the banks I think they could still manage when Bitcoin started to get mass adopted, cause here in my country PH, There's already banks that are open and acknowledging crypto which gave them a high rates and good feedback. Some banks would take time to do the same as well as they gather more information about Bitcoin if they can't handle the volatility.

The world will continue its spins without Bitcoin or cryptocurrency and you can live well without it. There are even people who dislike Bitcoin and cryptocurrency but their life just has never been worse or stopped.

What belongs to future will be adapted by people who live and work in future. It's not too hard to adapt if it is something relates to your jobs and income. When you must do it to maintain your livelihoods, you will do it even you dislike it.

Work from home, work remotely, you can do it during pandemic time and after the pandemic. I am sure people can do it with Bitcoin and cryptocurrency, if the time comes. Like how they have to do it with the Internet, Windows, Microsoft office ...

Some people are knowledgeable about Bitcoin but still rely on traditional banks. However, I believe there is a significant distinction between the two, and eventually, banks may adopt cryptocurrencies for other services.

Eventually, individuals will begin to adopt it and use it to their advantage.

Many countries will embrace crypto-currency once they understand its importance, and transition is not a curse. Transitioning can provide us with greater freedom, more opportunities, and numerous benefits.

If your acquaintances cannot trust banks, they will not trust this currency system. They continue to depend on either cash or gold.

Feel free to ask questions in this forum, but please search first since many questions from newbies have already been answered.

In general, the people are already bitterly facing the huge problems brought by the current monetary system. If Bitcoin will one day dominate the world, there'll be disruptions which might be interpreted as sheer havoc wreaked by Bitcoin, especially by its critics. The truth is that these will be minor ones as compared to the continuous damage caused by fiat. And these are necessary, too. But we surely won't be crying a river when the money printer operator would finally lose his/her job.


I think the banks won't go. Their roles may significantly change, though. Custodians will never be completely erased from the face of the earth. Plus there are also banking services that Bitcoin might not be able to replace. But, again, that the staff of banks will have to move jobs because of Bitcoin is never a heavy toll as compared to sticking with the status quo in which the people's currency is devalued nonstop.

 

Don't liken Bitcoin adoption to a bomb dropped from the sky. Why would people be surprised when the growth of Bitcoin is gradual? Right now, we're heading that way already. This has been going on since Bitcoin came into existence. It has been 14 years already. So, why would they be shocked when Bitcoin reaches a certain level of success? Bitcoin is a movement.   


Lack of understanding is easy to address. They only have to spare some time learning about it. Governments must have already heard about Bitcoin. They can easily invite experts to provide them better enlightenment. What's hard to address is stubbornly sticking to the fiat standard despite fully knowing how damaging and poor of a monetary system it is. The only way governments are closed-minded is when their leaders are benefiting so much from a rotten currency.


Gold and cash may be good but hard to keep. Moreover, they can easily be seized or stolen. They can also be damaged in many ways. They can't easily be moved anywhere, especially across international borders. They can easily be confiscated as well. As to cash, it might be replaced with a digital version sooner or later. As to gold, it can't be used as a currency. In which case, Bitcoin is much much better.

This lies on the "IF" idea that crypto would dominate the world. And even if it did, it doesn't take into account that there's a huge gap in time between the now and the then instance of this happening. All of the factors OP said pretty much involve ignorance of what crypto is. Said gap in time is more than enough imo for people to learn crypto if the world was actually swerving towards to using it for the majority of transactions.

If it was idk, late 19s or something then it might be hard, but even now you'd be hard-pressed to find someone who would have a hard time learning the basics of something they want if they needed to, but now? The internet itself helps a lot already, imagine what other types of helpful tools can be developed by the time that crypto is deemed as necessary, if ever.

Adopting Bitcoin even in large scale basis by the mainstream population does not really translate for banks to get closed out of business and resulting into a number of unemployed people. In my view, that thinking is very simplistic. Remember that banks have so many functions that Bitcoin could not cover...in fact many banks are now so diversified in their services all because they are also convinced that putting eggs in one basket can be a very risky proposition. Now, having said that, banks can now also be be dealing with Bitcoin and cryptocurrency acting as a broker using their name and reputation as a big leverage. We are a very diversified economy, there are so many thinks that banks can do in doing business and making sure they can pay their employees.
