I was thinking about the Bitcoin and it's Future in Banking . can it remplace money in transactions ?

goog question, i think bitcoin could have the theoretical potential to become the next banking system.

BUT only theoreticaly, and only in a far theoretical future.

before bitcoin can become the next banking system it has to overcome major obstacles, such as raising the transaction rate.
in order to be a major bankiing system youll need a fucking high transaction rate. and im speaking about probable millions of millions
of transactions per second. before bitcoin can be there we will need a lot more nodes in the lightning network.
thats a hard obstacle to overcome if not very very hard obstacle at least with the current version of btc.

another big proboem would be the private keys, currently there is noway to keep private keys save and easy assesble at the same time.
as saver the private keys are secured as unconvinient they are to use. unless we dont find a solution for that it will stay a far future.

a next big problem is definitly the energy consumption, imagine millions of transactions on the btc blockchain. and imagine how much energy
the mining process would require.

theory is good but practically i dont see no way that btc could become the future of banking, at least not with the current code. maybe with PoS the could be a little chance but i dont think so.
maybe as digital gold btc could find a place that could fit his properities perfectly.

Yes it can, but it will never be just like a bank, because it is a protocol and everything is runned on a "blockchain". Look for more information on this forum if you are really looking to learn more.

I think that bitcoin will play the role of a cumulative tool in the future. But the rest of the altcoins can take the place of real money in the banking system.

the real question

is banking via people partnered with corporate hub in a LN smart contract, .. replacing bitcoin

only those that have fully read the LN code and understood LN, should answer
only those not fooled by the over promises and under delivered features should answer

Bitcoin may not be able to replace the banking transaction system but maybe the bitcoin applied blockchain technology can be adopted by the bank to be used as a transaction system. The advantages of this technology are also already known by some economic observers that can solve the problem of transactions so far let alone Ripple has become a good example of the adoption of blockchain technology for having established cooperation with banks from California.

Bitcoin alone may certainly not be able to replace banking transactioms for sure because it is not a monitored system which is pretty unlikely for any government to allow working in full swing overtakinh the whole banking system. However, it can work as an aid to the digital money and online transaction market as an alternative means to the normal banking transactions.

That being said, the technology that bitcoin introduced which is the blockchain technology, upon which many new cryptocurrencies are made today,  can be an inspiration and a pathway for future money. This technology can be used by different countries for creating their own digital currency and in doing that, the paper money is more likely to be replaced by digital market taking place of banking transactions

I don't think Banks will be replaced by Bitcoin soon. I think it's more likely that banks start to use blockchain technology to provide better and cheaper service.

Bitcoin will not replace the banking system. But it will certainly be used for transactions, moreover it will be the main transaction system, when the lightning network is live. However, banks will have their own cryptocurrencies for their transactions.

I doubt that bitcoin will replace the bank. Rather, he will be an alternative to him. Or the Banks will take a blockchain, and adjust to crypto-currencies. One can say only one thing, that crypto-currencies will densely enter our lives.  ;)

actually Not Bitcoin that replacing the future of the Banking system but the technology behind Bitcoin is what replaces the Banking system
that is Blockchain Technology, i think Blockchain will replace the current banking transaction system.

I dont think that is going to happen very soon since these days bitcoin is used more like an investment than like a currency to pay for different things. Money are used by everyone and you can use them everywhere by exchanging them through different currencies whilr with bitcoin you cant even buy a coffee. On the internet bitcoin is promoted as being and investment from where you can get profit. I never saw someone promoting bitcoin as a new currency that you can use to pay for things faster snd without fees because that is not true. Thats why I think bitcoin is never going to replace money or credit cards.

I don't really think that a bank needs a bitcoin kind of system for transactions (because of the decentralized manner of the blockchain system of bitcoin). What a bank needs is a safe and secure (and quick and cheap) system that can be controlled. If it works on a kind of blockchain model or not, it does not matter at the end if it meets the requirements. Of course, banks would be happy with a blockchain based cheap and centralized system, but in this case they have to develop it for themselves. (And to agree that most of the banks will use that system, to be compatible with each other's system).

Though, it is not possible to completely replace the banking transaction system with Bitcoin. Yes,however, the use of bitcoin blockkain technology can be a bit more advanced. And gradually, maybe Bitcoin will become a major means of banking transactions.But For now banks and bitcoin are two separate sectors.

I'm pretty sure the cryptocurrency will replace the use of money in every transaction in the future, big Banks that do not see this threat will definitely go bankrupt.

It may happen or not, let us see no one knows what will happen in the future, it is hard to tell conclusions or predictions right now as some countries still not embracing and still hates crypotocurrencies so let us see in the coming years.

Bitcoin will never replace the future banking system but the technology behind bitcoin the blockchain may certainly replace it, as you can see people are starting to learn it especially those who in a financial institution. There are so many advantages if blockchain could be implemented on the our conventional bank system such as lowering cost, cut middleman, acceleration etc. I'm waiting for the firs bank in this world fully adopt it.

No, the world will not allow a decentralized system to take over the financial system of each country. Bitcoin will just be an alternative to banks, once it goes mainstream (one day I hope) people will look at Bitcoin as another alternative for payments, but banks will still be around, there's just so much stuff going on behind the banking system (god things and bad things behind the scenes) that it'll be pretty difficult for it to dissapear.
I think banks will either implement the blockchain technology into their system for a centralized digital currency to try to compete with Bitcoin and other cryptocurrencies, or they'll learn to coexist with the cryptosphere.

 No it will not. Bitcoin's price is too high to replace a regular currency. Likewise, it would be difficult also that all people people in the world would own a bitcoin. In my country alone, we have 100 million people while there are only 21 million supply of bitcoin. It would impossible also to replace physical money.

I has the potential to do so, and many high profile figures think the same, but if that ever happens it would be in decades from now. Probably only after the world experienced some great crash again, or more than one. Before that, I do think banks will use blockchain to compete with Bitcoin, or to try to send the message that we don't need BTC to have fast transactions. The thing is, that BTC wasn't created to just speed up transactions. It was created to be a decentralized currency, with all the advantages that brings. Of course governments probably wont like that a lot, and banks will definitely hate it, so it will be hard for that switch to happen. I think think we will first just see BTC as an "improved PayPal". Only after it succeeds as a payment system, it can aspire to become something more.

There are also fractions of bitcoin. There is no need to have 1 bitcoin. And the limited supply is one of advantages of bitcoin. It's great that it is impossible to print money.
I personally think that bitcoin introduced the technology and probably another coin which might has not created yet, can play the role for the transactions.

I believe that Bitcoin will eventually be able to replace the transaction in the banking sector, but we need time for this, the transaction speed is still too small.

what about ripple? isnt that a mix of both inerests? i dont think their interests are absolutely opposite, both are providing a similar service and banks can profit from cryptocurrencies as xrp shows so why should they be so opposite?

It doesn't really matter what price Bitcoin is. You will start counting in satoshi as soon as the price reaches a certain point and is used worldwide as currency.

Going back to the OP question, i believe it will replace money we have nowadays for transactions in the next 10 years.

Completely replace can not, because bitcoin is not controlled, but banks can use the concept of blockchain to simplify online transfers and transac- tions

I don't think it will be able to replace the future banking system. More people will use and own it but it would remain as that, an asset or a currency and it will co-exist with fiat money. Banks would find a way to not lose their business and they are currently studying or maybe some even started already the implementation of blockchain technology to combat cryptocurrencies. Blockchain is being studied by big companies already and there is no doubt that if ever the users of cryptocurrencies will grow, maybe they would eventually launch their own crypto like what Venezuela did. It would be like a crypto but controlled by banks and government.

I do not think that will ever happen, because the interests of the current banking system and the principles that gave rise to the cryptocurrencies are absolutely opposite and irreconcilable, so I think that for a long time both financial schemes will continue to march on its own paths, although I think that with the passage of time there might be certain points of encounter and coincidence as there is a growing regulation towards the use of cryptocurrencies.

In any case, the interference of banks in the ecosystem of cryptocurrencies should never be considered as desirable given the merely speculative and immoral interests of the current banking system.

The Technology behind bitcoin blockchain is replacing future banking system soon we can see blockchain based transparency banking system

The banking system does not need bitcoin but it will certainly use this awesome blockchain technology in future. In case of bitcoin i think it will remain as the same thing as today.

I believe that time will come soon and we will completely abandon paper money and the banking system.They will be replaced by bitcoin and altcoins.More precisely, the world of digital money and digital technologies will come.The machine is already running and there is no turning back.So if someone does not know where to invest-my advice to you in cryptocurrency.

That is the intention of the crypto world and it is attracting fear to the banks and to the government and they fighting the crypto world at all  cost in other to stop it vision.

Seeing the current development of Cryptocurrency is very fast, it is not impossible if Bitcoin and Cryptocurrency will replace the banking system that is currently in use. of course the more advanced, more modern technology. and it is not a thing of perception if Cryptocurrency replaces banking.

I do not think it's possible to see many banks against bitcoins now, they probably are afraid of being replaced by a more modern blockchain system. So with the development of the times, I have seen many banks have the latest innovations developed in which the society can be easier in transactions.

 I think that bitcoin and other altkoins will necessarily replace the future banking system. They will change the entire global financial system.

I think that in the future the system of banks will be completely changed. It will become a decentralized repository. Very fast and safe.

Not replace, since majority for now is still and will use money to save or put amount in their saving account, but Bitcoin may fasten things when it come to depositing money from online to bank account since you don't need to walk to the bank to save but only send it online and check the transaction if its verified and done.

There is a high possibility of happening so. Some big banking corporations are discussing about blockchain. And there is a possibility of accepting btc in their transactions system.

yes, it  is true. the bitcoin will replace the future banking system.

            Bitcoin is not replacing the future banking system and it cannot be since banks  decides to lend money  and Bitcoin is against taking decisions about lending money. Banks are really worried about Bitcoin since these virtual currency are transacted without the involvement of a banking sector . People can transact money without a third party influence and the currency can be transferred easily with low fees around the globe. Bitcoin has many potentials one of the drawbacks that Bitcoin has the value is fluctuating and it is not stable.   

I think it can. Now days in various field use in blockchain technology to provide better service. Bitcoin surly replace in future on banking system and other altcoin also replace in real money.

Many theories that explain bitcoin will replace the bank in the future if bitcoin is received by the country. Because many advantages of bitcoin that can compete with banks. Therefore, many banks work with the government to block the bitcoin in the country.

There is a high possibility for bitcoin transactions to replace the banking transaction system but this can only happen if about 50 to 70% of the world population participate in bitcoin transaction for goods and services..

Is your money greatly secured with your online wallet? Will you be able to easily access it tru several ATM available? Would there be any insurance if your assets will be lost or stolen?

If yes then maybe it could replace the banking system.

yes, bitcoin have a chance for replace the bank system, but at first, bitcoin should make it as zero fee transaction, then Im sur bitcoin will have the possibility for being great. Or at least bank system will support the bitcoin and blockchaim system and implement it to them.

I am also a bitcoin investor. I am curious to know that I can put the operating methods in each coin but commercialize it so that it can be applied to daily life or just an invisible system that is made only for financing through ICO.

If to replace it seems quite difficult. Moreover, each country has a central bank that is used as a tool to support economic stability in the country. Another case if the country makes its own cryptocurrency. It could be an alternative to the ease and financial advancement of the system in the future.

Hello everyone, I think that in future the crypto currency will replace money. Crypto currency is much more efficient than banking systems

Yes, of course. Bitcoin can be an alternative bank in the next few years. Bitcoin is created as an alternative payment method and also as an alternative investment. And now many ICOs are using Blockchain to create the Bank in the world of cryptocurrency.

No. Bitcoin couldn't offer secured transsctions with wallets. There's no insurance bitcoin could give if my tokens will be lost or stolen. And lastly, bitcoin cannot be accessed easily unless you have internet.

Bitcoin will never replace the banking system. But the block chain technology behind bitcoin is very good, and if the blockchain can be implemented in our traditional banking system, it will be of great help to them.

To replace banking with bitcoin for the future I think it's very difficult, and I believe that bitcoins and banks have their own way, but banks will take advantage of bitcoin and also Blockchain technology.

Maybe if bitcoin is received in a country with a majority of banks, I'm sure the bank will be rivaled and will eventually be replaced by bitcoin. Because the excess bitcoin is much better than the bank that we know.

Bitcoin can replace the banking system if the system will be completely changed. I am not sure it would work with current financial system.

I'm sure it could be, because bitcoin many advantages that we know. And what I see bitcoin is better than local banks because its payment system is fast and secure too.

until whenever the bank will never be replaced when there is a digital money appears like bitcoin just the opposite bank will help us to make it easier for us to use bitcoin in any case eg in the case of converting bitcoin currency into conventional currency and change it in physical form can through bank.

I think banking system cannot replace by bitcoin, they have different functions and I think more new high technology would be introduce to us.

Bitcoin has a lot of potential to replace the banking system although it is not the reason why BTC is created many people wants it to happen because they can see that it has a better qualities than banks.

If we talk about big system how banking there right to say what it be replaced not by bitcoin, it will be replaced by common blockchain technology

Gradually it is happening and it can replace the banking system if everyone accepts decentralized money but still many people are not aware of the crypto currencies so we need more years to know that it will happen or not.But until now crypto has some rapid reputation from last year but still that adoption is not enough we need more adoption rate to get stable price for crypto currencies.

Cryptocurrencies surpass fiat currencies at some point in the future. One important consideration is that cryptocurrencies cannot be manipulated quite as easily as fiat currency, largely due to their decentralized and unregulated status. Beyond that, cryptocurrencies could better support the concept of a universal basic income than fiat currencies would. As a matter of fact, some programs have already experimented with the use of cryptocurrencies as means of distributing a universal basic income. Finally, I don't think bitcoin will completely surpass banking system.

As Lagarde emphasized, the vast majority of cryptocurrencies such as bitcoin and Ethereum are still struggling to solve their underlying scalability issues. Previously, in an interview with major South Korean financial news publication JoongAng, Ethereum co-founder Vitalik Buterin stated that it could take two to five years for public blockchain networks to scale with two-layer and on-chain scalability solutions.

Yes Bitcoin may not be able to replace the banking transaction system but possibly Blockchain technology applied Bitcoin can be adopted by the bank to be used as a transaction system. The advantages of this technology are also already known by some economic observers. That Bitcoin will play the role of the cumulative tool in the future.

if bitcoin replaces payments for the future I still have not thought at all. if bitcoin goes hand in hand with the banknote payment it is most likely to happen in the future .

Why not in one hand, but in another hand it is very hard for world economy system to perform a thing replacing like that in general...

may happen if bitcoin replaces future payments. but it still takes a long time and process. if we look in terms of the state of bitcoin now. but the value of banknotes also we can not deny will still go along with bitcoin .

Bitcoin for sure can not replace banking transactions for sure because it is not a monitored system in short anonymousity of transaction. government will not allow anonymous transactions for cash flows. But it can work  and help as an alternative to pay for online transactiond through the help of your government

If everyone can transact independently and do not need to go to the banks then this will certainly have a major impact on the financial system in the future, banks will be lonely and abandoned by customers so that someday banks will disappear.

I think Bitcoin can replace the bank in the future. But if the Bitcoin price is high then the cost of sending and receiving will be very expensive. So I think the bank will still exist to adjust Bitcoin prices

Well bitcoins was designed to provide the basic financial freedom to its users , so that they get more privacy and no interference between then and their earnings .
 we should also take a look at the advantages offered by bitcoins to its users , at this rate of increase in users , yes it is possible that BTC can replace banks , or for survival banks would opt bitcoins .

Bitcoin can not replace the banking system. It is simply not suitable for this purpose and has no corresponding functions. Bitcoin is a very peculiar means of payment and nothing more. However, simply money can not replace the banking system. This is silly. Another thing is that the banking system can use blockchein technology to improve its efficiency in the work. To do this, there is a specialized ripple crypto currency, which is now used by many large banks.

It depends on merchants if they accept cryptocurrencies then all people start to use crypto but it is not possible until our government accept crypto as legal currency. I think it's a never ending story so the Bitcoin will not affect the banking system and banks will never disappear.

maybe the bitcoin applied blockchain technology can be adopted by the bank to be used as a transaction system. The advantages of this technology is also already known by some economic observers who can solve the problem of transactions so far.

Banks are be one of the biggest victims and rivals of BTC, as you don't need services of banks or any other intermediary if you are sending BTC. If BTC is accepted as global currency, banks will cease to exist and this is something banks won't let happen.

Bitcoin has the potential to do so, but I think traditional banking system will prevail and also they will manage some way to collect bitcoin for interest from people.

Does Bitcoin replace the banking system of the future?
I think not, because the bitcoin payment system through the bank, while the bank does not create bitcoin and can not send the funds in the form of bitcoin.

it may happen that bitcoin will replace the banking system but all are only limited to digital, this is called the banking topology front.
I am sure it will happen in the future

There is possibility that bitcoin could replace the banking system. But this will only happen if all seemingly problems and battles are won. Bitcoin needs major perfection before it can replace the banking system. It has some advantages that will really help it , but some defects also needs to be taken care of like transactions fee, major reduction in the value, wallet safety to avoid hacking and so on. If all this can be solved, then maybe it could be considered as a new banking system.

Idk about bitcoin, but blockchain will be in these structures ctures for sure  8)

Banks are thier own ways of transactions and bitcoin has it's own transactions it may not be going to happen they are on different ways  to find improvements to serve the community.

I think the point is that bitcoin can't replace money, and in transactions.. I think it will have a certain system or a particular support regardless of the banking system that only manages the common currency/fiat. But maybe if officially the whole of the countries bitcoin really get support, the banks will add a special system to handle bitcoin.

for me bitcoin can't replace the banking system in the future, why? because banking system in a country is very important to regulate the money in a country. and maybe bitcoin can be beside the banking system with mutual benefit, if the user wantt to make investment with secure system they acn use bitcoin and use banking system to use it daily

Bitcoin will never replace the banking system. On the one hand, bitcoin is simply not capable of this. Can, for example, bitcoin credit the development of the country's agriculture? Will he be able to serve the country's budget?
On the other hand, if bitcoin could replace all banks, the state would not allow it. Without banks, the state can not function fully. Banks are now an integral part of it. No state will allow uncontrolled circulation of money inside the country and especially its movement outside the state. Monetary and financial systems are the guarantee of stability and power of each state. Therefore, if bitcoin threatens the existence of banks, the state will be forced to restrict or even prohibit the circulation of bitcoins.

Banking system has been in the industry for generation, and it has greater impact in the economy, people, and the country. Bitcoin is an innovation, has so much contribution and offers great opportunities. It has so much potential to grow but its total mass adoption may take years and replacing banking system may not be an easy task. Banking system is strongly regulated by the government, is already an established system, and does not need internet or electricity to process any transactions by the use of cash. I think, despite the differences in technicalities, both can still function on its own very unique ways, either centralized or decentralized.

Can it replace fiat currency in transactions? I think yes. We're already seeing that happening right now, as people are buying a range of stuff online with bitcoin for the sake of convenience. And this adoption is only going to increase as time goes on.

Though, it is probably not going to replace the current fiat banking system altogether.

In some ways, bitcoin is going to be like gold, except much more convenient and just better in general as it is fully decentralized. It will probably co-exist with the fiat banking system, unless it collapses, where bitcoin has a legitimate chance at becoming the single global currency of choice.

maybe in the future? no one knows? but I think that it will be a alternative not that replacing the banking system. Banks having a different specialty and operations the same  as bitcoin. I will be happy if this thing come true with the range of 10-20 years.

Bitcoin as the leading cryptocurrency may still not be the leading form of exchange and store of value since banking  comes first and has already deep-rooted for centuries. Bitcoin can hardly overpower banking system because it is strictly regulated and also the adoption is wider and bigger. I think there's no easy way for bitcoin to replace banking system, or maybe if it could it would take longer time, longer patience, more hardwork, and more challenges to face along the journey.

Why are people always mixing banks and cryptocurrencies? These are two different things and systems and the purpose ofis cryptocurrencies is not to replace anything. Not Bitcoin or any other cryptocurrency will not push out the traditional financial system. It can make it function differently and more adjusted to current needs and modern technologies but that is all.
Banks will continue to exist as the basic financial pillar and the cryptocurrencies will be the alternative and paralel decentralized system.

I think BTC is very difficult to replace banking!

The BTC and cryptocurrency haven't been accepted by many.

The bank is the national financial environment an important car rental part, the economic development cannot leave the bank!

You are totally right about their differences and purpose, but I think the question as to whether there is a possibility of bitcoin replacing the banking system in the future. The future can be in like 50 to 100 years time to come, by then there will be more advanced technologies available and more people will be exposed to the world of cryptocurrencies. The question wanted to know the possibility of replacing the old centralized system to a decentralized system in relation to bitcoin..

BTC can become a good alternative in the future, but not replacement.

Yes, I think it will happen. Bitcoin replacing banking system in the future. Because bitcoin is the future technology. we will see.

After we look at bitcoin developments from the beginning to the present, I also believe that even now the price is down but someday the price will surely blow up again, I believe bitcoin will rise again quickly.

I think yes, in the future everyone will use crypto-currencies and the need in the bank will simply disappear.

it is likely to be said that way because today the technology is increasingly sophisticated so that the bank is not too in need anymore if it has entered the era of digital currency and the existence of blockchain system.

I don?t think bitcoin will replace the previous curreny sustem, but we are going to meet new innovation because of it.

I don't think bitcoin will replace banking system in the future. However, banking industry will make use bitcoin whereby consumer can be depositing and withdrawing bitcoin. Also banking will adopt blockchain technology into their system.

I think it is not possible now, It may happen in future, customers may drop and withdraw bitcoin, if it is accepted by the bank. But Cryptocurrencies not control by a organization or a individual person, Bitcoin is digital currency. Banking system is totally different form digital currency. so don't confuse both.

I don’t think bitcoin will replace the banking industry, I only feel it will reduce the work load for them since we can only use their system when we want to collect fiat.

yes it could, maybe the system will be different from the Bank, because the Bitcoin system is run by Blockchain, and maybe the Bank can cooperate with Bitcoin, by implementing Blockchain technology on the banking transaction system.

There is no doubt that bitcoin has a potential to become a banking system.  However,  there would be alot of things to be considered. Like how would it be able for clients to take out loans and stuff,  since bitcoin as of today is known as a mode of payment into digital world,  it is still designed to do such thing and it would make a major transition to make it as a banking system considering all the restrictions that the government may imposed.

I believe it's already replacing the system. Banks are heavily investing in using blockchain technology for their internal needs. They won't get bankrupt because of bitcoin, they're trying to find the ways to apply blockchain, so when bitcoin takes over fiat in some parts of the world, they will still be able to offer derivates and other markets.

Bitcoin blockchain could be used for future transactions with money, but not bitcoin itself.
Governments and banks already testing blockchain in their needs, performing test transactions from one country to another using blockchain.
One of reason to do so is, human factor - with usage of blockchain there will be no human mistakes in payment operations.
Highly unlikely that governments will use bitcoin for transactions, as they can't control it, as well as highly volatile price of this asset.

The most valuable thing about Bitcoin is that he introduced the technology of blockchain to the world. here it is just able to improve the existing banking system. It greatly improves the speed, confidentiality and security of sending money. Blockchain is power. Its potential to change the world can be compared with the potential of the Internet.

you have a point it can actually be used for but not bitcoin by itself to used in a transaction where we can be able to see and used this as like as a fiat and as just how the internet must have some development this is where bitcoin may does too.

Why does anybody think that something needs to be replaced, these two can both work with the presence of the other. We need to get the most out of both therefore let them work best at what they do and use them as is. Bitcoin can be used as your digital currency and store using wallets, and banks can do banking stuff where you store your physical money.

Certainly not in my country. If you will visit a rural bank in my country , you will find that 90 % of them cannot even fill the bank forms by themselves. I do not expect them to use bitcoins ever in their life. I am not talking about old people only but even the younger generation is not that tech savvy in developing countries.

not anytime soon, but does have a potential

Bitcoin and the banking system perform completely different tasks and functions. Therefore, bitcoin has no chance to replace the banking system as a whole. Bitcoin is primarily a means of payment, that is, money and, in addition, it is now largely used as a repository of value. In addition to these functions, banks perform many different other functions. First of all, in any state, banks define the credit and financial policy, they credit certain sectors of the economy, help the state fulfill the plans for the country's economic development. Bitcoin of these functions can not perform. Moreover, due to its high volatility, it is capable of completely imbalancing the economy of any strong state.

Yes. I do believe that bitcoin is in a way replacing the future banking system and it also has the right amount of potential of doing so. This is because since bitcoin has started. It has gained a lot of popularity among the people all around the world because of which it has gained a lot of potential investors and potential users who are ready to invest in bitcoin. This signifies that bitcoin’ Demand among the people is increasing a lot. All this is evident from the increasing price of bitcoin daily.

There are more rumors about bitcoin will replace the existing money that we used and called as fiat. But I think it will be hard for bitcoin to replace fiat since bitcoin is being banned on other country and many countries until now do not have trust on digital currency. I think bitcoin will not lose because many people uses bitcoin and also it has many investors as well as supporters. Bitcoin can also replace the future banking since bitcoin is used to pay bills and any other.

Each country has a central bank that is used as a tool to support economic stability in the country. Another case if the country makes its own crypto currency it could be an alternative to the ease and financial advancement of the system in the future.Bitcoin cannot be accessed easily unless we have internet.

 There are so many advantages if blockchain could be implemented on the our conventional bank system such as lowering cost, cut middleman, acceleration etc. I'm waiting for the firs bank in this world fully adopt it.

Im sure the bitcoin will replace any banking system, too much lack in it, and i think right now bitcoin is only great on campaign of decentralized exchange.
all the rest still in the bank system, we need to great at all that already exist in the banking system. anyway, there's still a lot people which more pros on banking system than bitcoin.

no bitcoin is only disrupting them, bitcoin isnt capable doing that, as promised in the marketing campaign, "bitcoin the a future world currency"

Well, having this new innovation in the real world, we may expect that this prediction would somehow come into reality. But it's not that easy to change the recent banking system because they have to be broad in gathering information on how this system works if they are going to adopt this technology.

Yes it can replace money especially in terms of online transactions. Since bitcoin transactions are cheaper and easier, it would be more convenient to use. If people just know the benefit of having a purchase in bitcoin. Although I do think that it can replace money in the future, I believe that its not in the near future.
