Could digital currencies put banks out of business?

 

The fundamental principles of banking have been the same for centuries and revolve around the greatest magic trick of all how to create money:

It’s called fractional reserve banking.
Here is how it started Hundreds of years ago banks stored gold for investorsBut they realised it was unlikely everyone would claim their gold back at the same time,So they began to loan some of these gold deposits out to other people.This made money for the bank through interest and helped power the economy by allowing idle deposits to fuel new business and trade. As time went on, the banks started issuing bank notes or IOUs—rather than physically giving out gold and these IOUs started being traded in the economy.This meant the amount of money in circulation was much larger than the value of the gold held by the banks,So the banks’ lending had in effect created new money.Nowadays, most money is digital.When the bank makes a loan it creates a new asset on its balance sheet and credits the borrower’s account with new funds which creates a new deposit.The fundamental principle is the same.Every time the bank makes a new loan it creates new money In fact, 90% of money in the world is digital deposits that have been created by banks in this way.This is hugely important for the economy.What it means is that banks are able to respond to demands for money in an economy and that means that the supply of money in the economy is very elastic.There is no set amount of money in circulation,So if the economy is booming and more goods are being created then thanks to fractional reserve banking the supply of money should also increase as people take out loans and make new investments.The ease with which commercial banks can create money is largely controlled by central banks like the Federal Reserve, which set interest rates.If interest rates are high banks pass those costs onto  makes it borrowers.Thismore expensive for them to borrow money to buy things and so banks create less new money.Central banks also supply money for use in the economy,They print the physical paper cash people carry around and so banks and central banks balance the need to create money between them, That sort of balance means that, you know, money can grow easily with demand but also that the central bank has sort of a direct presencei n payments and transactions, But this delicate balance is under threat thanks to a revolution in the way people use money.For a start an increasing number of businesses no longer rely on banks for loans.This is because businesses, historically used to create concrete assets—like machinery against which banks were happy to lend,They could always claim the assets if the borrower stopped repaying.We know you are reliable,I’m glad you think so but intangible assets like software can’t easily be posted as security for a bank loan.The world has shifted in a way that does makes it hard for banks to fund the, sort of, most innovative parts of the economy.If you want to get funding as a Silicon Valley startup in general, you’ll need to go to people who are equity investors…
so they take a slice of your business in
 return for some money and it is not just innovative startups that are turning elsewhere for funding.
Since the 1950s the share of bank loans as
 a percentage of GDP has been relatively stable,At the same time, non-bank loans and securities have risen sharply,This means the role banks play in financing important businesses is receding and that’s not all,The way people move and spend their money is
 changing too—thanks in part to a new class 
of mega-apps from China.One of the most popular is Alipa from Chinese tech giant Ant Group It has over a billion users and handled $16trn in payments in 2019.I am Alipay I have a dream to create a world where mobile payment replaces cash paymentRather than using bank cards to make payments Alipay customers carry out transactions…by loading money into digital wallets.They can then do anything from buying lunch to investing in stocks and shares—all without leaving the app and rather than paying expensive international transaction fees to their bank Alipay users can also use the app overseas.You’re already seeing this even in America.You know, Walgreens in the States accept Alipay.This, sort of, new digital payments ecosystem sort of completely disregards nation states and national borders It’s not just Alipay Facebook is developing its own digital currency and Amazon is also working on financial services.Some worry this could concentrate too much power in the hands of a few tech companies.But, for central bankers, the problem is even more acute.they fear these developments could cut the cord between the central bank and the economy altogether.The super apps in China, they started off just doing payments and now they do provision of loans,they do provision of investment services, they provide insurance.You know, they do all the things that banks do,Central bankers feel as though their, sort of, ability to oversee and conduct monetary policy and oversight is, you know, fundamentally slipping away,So some central banks have taken radical action by creating their own digital currencies to rival the tech giants’ payment systems in the hope this will secure their grasp on the economy.
Central bankers’ level of discomfort is
 potentially prompting them to, sort of, act to change this, you know, economic system the monetary system that has underpinned modern economies for, you know, 250 years,China is one of the largest economies leading the way by trialling a digital yuan.You might have heard of Bitcoin or other digital money that is supposed to disrupt finance,But digital currency issued by governments in this way might be even more radical.
Here’s how it works:
Most central-bank money is held by commercial banks as
 reserves against customer deposits.You can only access a small amount of this government-made money via physical notes and coins,As this physical cash is issued by the central bank in the UK bank notes are even signed by the chief cashier of the Bank of England.A central bank digital currency—or CBDC—is a bit like digital cash as it gives the consumer a direct relationship with the central bank.
So in theory, instead of keeping your money in
 a commercial bank you could hold all your money in the Federal Reserve or the Bank of England CBDCs are only being used or trialled in a handful of countries worldwide,But they’re growing fast 80% of central banks are considering issuing them in the future.The Bank for International Settlements which is a club of central bankers says that within three years a fifth of the world will live in countries that have this central-bank digital money,This could change everything,If everyone put their money into a CBDC then fractional reserve banks could potentially be out of a job.This could affect economic growth as they could not rely on consumer deposits to finance their loans,And
 this would be particularly pronounced in
 the developing world where most lending still comes from banks,But that’s just the beginning,There are also concerns about potentially, you know, cyber-warfare,Because if you can take down the servers that support the central bank digital-wallet system then you could shut down an entire economy.Digital currencies could also increase the potential for state intervention in everyday transactions,It becomes much easier for governments to completely block your ability to pay for something,It’s very easy to imagine that, you know, perhaps you could program, you know money in China so that it can’t be used to pay for books or newspapers from foreign sellers,Supporters of CBDCs claim they could lead to a world where more people have access to financial services and it’s cheaper and easier to move money across borders,But innovations like this could also disrupt the financial equilibrium and give governments far greater control over their citizens’ money and lives So, although it’s possible for the first time in modern history to imagine a world without banks you might just find you’d miss them,if they were gone.

Bitcoin mining

 What is Bitcoin mining?

Bitcoin operates as a peer to peer network.
This means that everyone who uses Bitcoin is a tiny fraction of the bank of Bitcoin.But where do Bitcoins come from?
With paper money a government decides when to print and distribute money.
Bitcoin doesn't have a central government.With Bitcoin, miners use special software to solve math problems.And are issued a certain number a bitcoins in exchange.This provides a smart way to issue the currency.And also creates an incentive for more people to mine.Since miners are required to approve Bitcoin transactions more miners means a more secure network.
The Bitcoin network automatically changes the difficulty of the math problems depending
 on how fast they are being solved.In the early days, Bitcoin miners solved these math problems with the processors and their computers.Soon miners discovered that graphics cards used for gaming were much better suited to this kind of working.Graphics cards are faster, they use more electricity and generate a lot of heat.The first commercial Bitcoin mining products included chips that were reprogrammed for mining Bitcoin.These chips were faster but still power-hungry.ASIC, or application specific integrated circuit, chips are designed specifically for Bitcoin mining.ASIC technology has made Bitcoin mining even faster while using less power.As the popularity of Bitcoin increases, more miners join the network making it more difficult for individuals to solve the math problems.To overcome this, miners have developed a way to work together in pools.Pools of miners find solutions faster than their individual members and each miner is rewarded proportionate to the amount of work he or she provides.Mining is an important and integral part of Bitcoin that ensures fairness while keeping the Bitcoin network stable, safe and secure.

Bitcoin explained and made simple


many people have tried to work out how to
 have a payment system without that middleman but then there's another problem. how do you prove that you've paid for something or even that you have that money at all without someone vouching for you it's so serious it has a name the double spending problem then in 2008 a solution was offered by an anonymous programmer going by the name of Satoshi Nakamoto Nakamoto left a paper on a popular cryptography blog which proposed a system of currency that solve all of these fiddly problems his proposal was that instead of a bank or credit card company recording every transaction in one central ledger all of the users would record all of the transactions at the same time as a result any attempt to fool the community would be noticed and the payment rejected no one user government or bank can force a fee on a payment or control its flow the result is a cheaper quicker and easier way to spend money even across national borders so this is Bitcoin and it's already starting to have an impact on people's lives
 within months of the proposal it was
 being used to buy and sell goods although
 not always from the most scrupulous
 of traders but it's not all shady
 businesses some shopping sites take
 it you can buy pints in London and even
 pay for your university tuition as you
 might have heard there are problems while
 some are profiting from getting involved
 early others are losing out from
 this volatile in young market and people
 are found in companies to buy up lots
 of bitcoins but as it's designed to have
 a limited amount ever in circulation
 that might cause problems down
 the road there's so much 
uncertainty around Bitcoin some people genuinely
 think this is the future others
 are terrified it could destroy our
 economy but many from both sides 
agree that if we could get Bitcoin to work
 or something like it if we can trust
 a digital currency to work without the
 middlemen then the way the world economy
 functions could be transformed for
 the better. 

What’s behind the Bitcoin hype?

Let’s talk about Bitcoin
It’s the most popular digital currency on the planet.
Bitcoin’s made some people real rich, real fast.And some major companies are buying in.But plenty of big names won’t go near it.
So can Bitcoin be trusted? How does it work? And what’s Bitcoin really worth?
There are thousands of cryptocurrencies out there but the one most people are talking about is Bitcoin.
It’s a digital currency but instead of dollars and cents it's Bitcoins and satoshis and one Bitcoin is worth 100 million satoshis.But unlike the dollar, euro or yen this currency isn’t controlled by a government.That’s what makes Bitcoin revolutionary. And to some people — a bit scary.It used to be simple. Countries would peg their currencies to the gold stashed in their central bank.But currencies are now just paper, metal or a number in your bank account and its value is guaranteed by a government.It’s why we trust it.We also trust the banking system to move our money — especially online.
So when person A sends $100 to person B the banks make sure that amount is subtracted from one account and added to the other.
And banks update their ledgers to make sure people aren’t spending money they no longer have.And, of course, banks charge fees for all that work to verify transactions.So what if there was a way to cut out the banks? Well, that was the original thinking behind Bitcoin.
The idea was posted online in 2008, describing a peer-to-peer version of electronic cash that you can send from one party to another without going through a financial institution.
Its creator, or creators, used the name Satoshi Nakamoto.It was a wake-up call exposing risky banking practices.Many people lost everything, including their faith in the financial system.Coincidence or not, Bitcoin turned up at the same time and 10 years later it’s still going.So, Bitcoin is not controlled by a government. It’s not a bank or a company.Instead it’s open-source software that runs itself — or more accurately, is run by lots of people.Here’s how.So first up it’s called a cryptocurrency because Bitcoin uses encryption to keep it secure.And instead of bank accounts people trading Bitcoin have two keys. One’s private and one is public.They’re not actual keys but bits of encrypted code that fit together.If person A needs to get Bitcoin to person B they send it to B’s public key. Think of it like the number on an ATM card.Person A uses their private key to encrypt the transaction and person B uses their private key to decrypt it and get their Bitcoin.Those private keys are like the PIN to the ATM card.Now instead of a bank verifying that transaction it’s done by a huge network of computers around the world.And they all have identical copies of Bitcoin’s ledger. It’s a record of every transaction ever made that’s constantly being updated.So if there’s any kind of fraud the whole network knows about it.That decentralised ledger is called blockchain.Bitcoin transactions are bundled into blocks and linked together.And each block contains a bit of code from the previous one, creating a chronology that’s supposed to be impossible to mess with.
So who are these witnesses?
Well, they’re actual people called miners with powerful computers.
Miners used to do it all on their own. Some still do.But Bitcoin’s grown. And now it takes so much more computing power and much more energy.So miners often band together in what are called pools.Some of them build huge warehouses of servers called farms.The big ones are in China, Russia but also places like Iceland where it’s just easier to cool those servers.There’s also a lot of energy involved.A Cambridge University study says the entire global Bitcoin network uses more electricity than Argentina.But what’s in it for all those miners?
Well, remember Bitcoin isn’t a company so miners don’t get a salary for adding to the blockchain.
Instead the system rewards them in Bitcoin.So, transactions are actually floating around on the Bitcoin network — like in a waiting room ready to be verified.Miners look for new transactions to bundle them in blocks.But before they can add a block to the chain there’s an extra security check that’s pretty unconventional.Mining computers have to compete to solve a coding puzzle.If a miner solves that puzzle first the block and all the transactions inside it are added to the blockchain and that miner is rewarded with some Bitcoin.Another appeal among crypto fans is this idea that Bitcoin is seen as a hedge against inflation.Other currencies suffer when, for example, more money is printed, diluting the pool and weakening its value.Bitcoin gets around the inflation problem by capping its supply at 21 million Bitcoins.At the moment roughly 17 million Bitcoins are already in circulation but there are a few million missing because some people have lost their private keys.So how does all the remaining Bitcoin keep its value? Well, the system slows that supply down.One way is by cutting the mining rewards in half every four years.In 2009 the reward was 50 Bitcoins for every block of transactions added to the blockchain. Four years later it was 25 and so on.In other words it’s basic supply and demand. Bitcoin’s supply is capped while demand grows. For now at least.So more people are coming around to the idea that Bitcoin could rival gold — eventually.But so far Bitcoin’s value against other currencies has been far from stable. It’s gone up and down like crazy.One of the big runs was when PayPal said it would allow users to buy, hold and sell Bitcoin.Others followed suit, including Tesla, owned by Elon Musk, which said it would start accepting Bitcoin as payment too.But is it? Not everyone gets it or believes in it.Yes, companies like Microsoft, PayPal and Mastercard accept Bitcoin. You can use Bitcoin to buy gift cards at Nike or Starbucks.But its use is limited.And while crypto enthusiasts think Bitcoin’s value is going to climb even higher — maybe even to the point where one Bitcoin is worth a few hundred thousand dollars — others say it’s just a bubble.There are other concerns with Bitcoin too.
If something goes wrong — you forget or lose your private key for example — there’s no customer service to call.
Another issue is Bitcoin being misused. Criminals like it because it’s anonymous.So regulators are already looking into it.In the grand scheme of things Bitcoin is still a pretty new concept.Some people are willing to take a big financial risk to chase a potential fortune.Others think there’s no way a piece of code is worth tens of thousands of dollars. It boils down to trust. Like any currency — for Bitcoin to work, enough people have to buy into it. There’s obviously a lot more to Bitcoin and cryptocurrencies, plenty of stuff that we didn’t have time to get into.

Difference between digital currency and cryptocurrency

Difference between digital and cryptocurrency


today i'm going to talk
about the differences between digital
 currencies and cryptocurrencies:
In a world of digital currencies in fact up
 here in canada we
 no longer even use the penny it's
 too expensive to make so slowly but truly
 that hard
 physical currency is disappearing we
 had the evolution of paper currency and
 then credit cards and now we even have
 wiring
 and paypal and venmo so
 the digital currency is being 
accepted now why is
 something a digital currency versus a cryptocurrency
 what's
 the main difference well the digital
 currencies are
 regulated by the federal banks of the
 con of
 the country so the u.s bank is going to
 control the
 u.s dollar the bank of canada the
 canadian dollar and so on so they are
 tracking
 all of this currency what's crossing
 the borders you
 know how much many times if you transfer
 an amount larger than ten thousand
 dollars they start to ask questions
 in
 fact even over nine thousand dollars many
 times they will ask you what
 is the purpose of this transfer why are
 you transferring it or
 any sort of cross-border transfer they
 will usually ask you and say why are
 you transferring this money which
 then brings us to cryptocurrency right
 cryptocurrency
 is decentralized there is no
 central
 bank that is following this currency
 
so it goes through an encryption process and
 it's all encryption
 between point to point for the
 transfers, that's
 the only way to track it and you store
 this digital currency in
 a crypto wallet sorry the
 cryptocurrency in a crypto wallet it is
 a form of digital currency but again
 it's not regulated which is why it's
 a crypto currency
 so that's part of the reason why
many people are skeptical of cryptocurrencies
 is because they aren't being
 regulated by 
anybody and some think that this is a perfect
 way.
for people to launder money because it does
 not go through
 a central bank. 

Could digital currencies put banks out of business?
