yes you are correct change is inevitable and there is nothing we can do to stop it. It is either you accept the changes or continue to dwell in the past. But I don't see money disappearing, instead I see it go hand in hand with bitcoin and cryptocurrency. Money has been used for so long and has established a lot to just disappear.

Not surprisingly, the most popular debit cards in the US. They can also contain the main types of crypto currency. As the infrastructure for crypto currency is still poorly developed, it is now very difficult to buy goods and services directly in the crypto currency. Debit cards eliminate this drawback. They combine the possibilities of crypto currency with ordinary money, because it indicates the currency and your funds increase along with the increase in the value of the crypto currency, and at the same time you can calculate at any outlet in the usual currency, however, a certain number is being withdrawn from your account and a crypto currency. It is very profitable.

There is a long way in replacement of real money with cryptocurrencies. However, we have a good start. Hopefully, we will reach a good result.

First, I want to express my opinion about this, in my country of course. i am a citizen of indonesia. the population of Indonesia is about 262 million people. while internet users in Indonesia reach 143 million people, about 50% of the population use the internet.
Blockchain technology in bitcoin requires users to use the internet, so half of our population should what if using bitcoin as a means of payment, I think this problem is faced by many other countries.

Second, the population of debit card and credit card users in our country is only familiar in urban areas. how many people still like to use physical money.

Third, bitcoin users in our country is still small, but has a tremendous level of assets. daily transaction 1.2 billion US dollars.

I think the use of bitcoin cryptocurrency technology should reflect the interests of the whole community. if imposed will bring destruction on such technology because of transaction scalability. I can not say which bitcoin and physical money are better, but I want to say they have their own value in the hearts of people.

Bitcoin is something that we can use through online payment that the advantages is you don’t need cash before paying some bills, in just one minute the trasaction is done. Real money is what we use since we have it and knew how to use it.

In fact, bitcoin is a digital money and it is like fiat that can be also used in different kind of transactions. Furthermore, fiat have exact value on market and it can be used both online and offline transactions while bitcoin you can't use it in offline transactions like paying in restaurants, fast food chain and many more. Lastly, I think bitcoin will become our future money but I guess it will never replace fiat.

Knowing the difference or to which is which bitcoin or money could be good may basically answered by the person who both use bitcoin and money, preferably those are the bitcoin users. Since bitcoin users itself uses money. Well my opinion is that this two are good use for transaction but will always be depending on the one who is using to make it good. That is why both could be use well and be sufficient if and only if we are using it in good.

For me, bitcoin is the real money, and bitcoin is the product of our technological progress, whether we like it or not, and the monetary system will change in the near future.

With the increasing use of technology this is bound to happen, digital payment options like bitcoin will flourish, I will not be surprised if the percentage rises to 60-70 % in next 10 years.
