I'm Nate Martin and I'll be your guide through this video series
[5]
Bitcoin Whiteboard Tuesday.
[8]
We're going to cover a lot of topics such as
[10]
Bitcoin mining, Bitcoin wallets, how to trade Bitcoin and a lot more.
[14]
Today we're going to start from scratch
[16]
and answer the third most searched term on Google today, what is Bitcoin?
[22]
If you’re worried that we’re going to get too technical
[24]
and use a lot of complicated words, don’t.
[27]
Here at 99Bitcoins we translate Bitcoin into plain English
[31]
so even if you have no technical background
[33]
you’ll be able to understand everything.
[36]
By the end of this course,
[37]
you’ll know more about Bitcoin and how it works
[40]
than 99% of the population.
[42]
So let’s get started

[50]
Before we talk about Bitcoin
[52]
I want to take a moment and talk about money.
[54]
What is money exactly?
[56]
At its core, money represents value.
[59]
If I do some work for you,
[60]
you give me money in exchange for the value I gave you.
[64]
I can then use that money to get something of value
[66]
from someone else in the future.
[69]
Throughout history, value has taken many forms
[71]
and people used a lot of different materials to represent money.
[75]
Salt, wheat, shells and of course gold
[78]
have all been used as a medium of exchange.
[81]
However, in order for something to represent value
[84]
people have to trust that it is indeed valuable
[87]
and will stay valuable long enough for them to
[89]
redeem that value in the future.
[91]
Up until a hundred years ago or so
[93]
we always trusted in someTHING to represent money.
[96]
However something happened along the way
[98]
and we’ve changed our trust model
[100]
from trusting someTHING to trusting in someONE.
[103]
Let me explain.
[104]
Over time, people found it too cumbersome
[107]
to walk around the world carrying bars of gold
[109]
or other forms of money, so paper money was invented.
[112]
Here’s how it worked:
[114]
a bank or government would offer to take possession of your bar of gold;
[117]
let’s say worth $1000,
[119]
and in return, that bank would give you receipt certificates,
[122]
which we call bills, amounting to $1000.
[126]
Not only were these pieces of paper much easier to carry,
[128]
but you could spend a dollar on a cup of coffee
[130]
and not have to cut your gold bar into a thousand pieces.
[134]
And if you wanted your gold back,
[135]
you simply took $1000 in bills back to the bank
[138]
to redeem them for the actual form of money,
[141]
in this case that gold bar, whenever you needed

[143]
And so, paper began its use as money
[146]
as an instrument of practicality and convenience.
[149]
However as time progressed, and due to macroeconomic changes,
[153]
this bond between the paper receipt and the gold it stands for was broken.
[157]
Now, to explain the path that led us away from the gold standard
[160]
is extremely complex, but suffice to say that
[163]
governments told their people that
[165]
the government itself would be liable for the value of that paper money.
[169]
Basically we all said
[170]
“let’s just forget about gold and trade paper instead”.
[173]
So people continued to
[175]
trade with receipts that are backed by nothing but the government’s promise.
[179]
And why did that continue to work?
[181]
Well, because of trust.
[183]
Even though there is no actual commodity backing paper money,
[187]
people trusted the government and that’s how fiat money was created.
[191]
Fiat is a Latin word that means “by decree”.
[195]
Meaning the dollars, or euros or any other currency for that matter
[198]
have value because the government orders it to.
[202]
It’s what is known as “legal tender” -
[204]
coins or banknotes that must be accepted
[206]
if offered as payment.
[208]
So the value of today’s money
[210]
actually comes from a legal status given to it by a central authority,
[214]
in this case, the government.
[215]
And so the trust model has changed,
[218]
from trusting someTHING to trusting someONE,
[220]
in this case, the government.
[222]
Fiat money has two main drawbacks:
[225]
1. It is centralized:
[228]
You have a central authority that controls and issues it.
[231]
In this case the government or central bank.
[233]
And two, it is not limited by quantity:
[237]
The government or central bank can print as much as they want
[240]
whenever needed and inflate the money supply on the market.
[243]
The problem with printing money is that
[245]
because you’re flooding the market with more money
[247]
the value of each dollar drops, so your own money is worth less.
[252]
When you see prices rising throughout the years
[255]
it’s not necessarily that prices are rising as much as that
[258]
the purchasing power of your money is dropping.
[261]
You need more dollars to buy something that used to “cost less”.
[265]
Once fiat money was in place,
[267]
the move to digital money was pretty simple.
[270]
We already have a central authority that issues money,
[272]
so why not make money mostly digital
[275]
and let that authority keep track of who owns what.
[278]
Today we mainly use credit cards, wire transfers, Paypal
[282]
and others forms of digital money.
[284]
The amount of physical money in the world is almost negligible
[287]
and is getting smaller with each year that passes.
[290]
So if money today is digital, how does that even work?
[293]
I mean, if I have a file that represents a dollar,
[296]
what’s to stop me from copying it a million times
[298]
and having a million dollars?
[300]
This is called the “double spend problem”.
[303]
The solution that banks use today is a “centralized” solution;
[307]
they keep a ledger on their computer which keeps track of who owns what.
[312]
Everyone has an account
[313]
and this ledger keeps a tally for each account.
[316]
We all trust the bank and the bank trusts their computer,
[319]
and so the solution is centralized on this ledger in this computer.
[324]
You may not know this,
[325]
but there were many attempts to create alternative forms of digital currencies,
[329]
however none were successful in solving the double spend problem
[332]
without a central authority.
[335]
Whenever you give a anyone control over the money supply
[338]
you’re giving them enormous power and this creates three major issues:
[343]
The first issue is corruption;
[345]
power corrupts, and absolute power corrupts absolutely.
[350]
When banks have a mandate to create money, or value,
[353]
they basically control the flow of value in the world,
[356]
which gives them almost unlimited power.
[359]
A small example of how power corrupts
[361]
can be seen in the Wells Fargo’s scandal
[363]
where employees secretly created
[365]
millions of unauthorized bank and credit card accounts
[368]
in order to inflate the bank’s revenue stream,
[370]
without their customers knowing about it for years.
[374]
The second issue of a centralised system is mismanagement.
[377]
If the central authority’s interest isn’t aligned with the people it controls
[381]
there may be a case of mismanagement of the money.
[384]
For example, printing a lot of money
[386]
in order to save a certain bank or institution from collapsing,
[390]
as what happened in 2008.
[392]
The problem with printing too much money is that
[394]
it causes inflation and basically erodes the value of the citizen’s money.
[399]
One extreme example for this is Venezuela,
[402]
where the government has printed so much money,
[404]
and the value of it has dropped so much,
[406]
that people are no longer counting money but are weighing it instead.
[410]
The last issue is control.
[412]
You are basically giving away all control of your money
[415]
to the government or bank.
[417]
At any point in time
[418]
the government can decide to freeze your account
[420]
and deny you access to your funds.
[423]
Even if you use only cold hard cash
[425]
the government can cancel the legal status of your currency
[428]
as was done in India a few years back.
[431]
This was the state of things until 2009.
[434]
Creating an alternative to the current monetary system
[437]
seemed like a lost cause.
[438]
But then everything changed
.
[441]
In October 2008
[443]
a document was published online by a guy calling himself Satoshi Nakamoto.
[448]
The document, also called a whitepaper,
[450]
suggested a way of creating a system
[452]
for a decentralised currency called Bitcoin.
[456]
This system claimed to create digital money that solves
[459]
the double spend problem without the need for a central authority.
[464]
At its core Bitcoin is a transparent ledger without a central authority,
[469]
but what does this confusing phrase even really mean?
[472]
Well, let’s compare Bitcoin to the bank.
[475]
Since most money today is already digital,
[477]
the bank basically manages its own ledger of balances and transactions.
[481]
However the bank’s ledger is not transparent
[484]
and it is stored on the bank’s main computer.
[486]
You can’t sneak a peek into the bank’s ledger,
[488]
and only the bank has complete control over it.
[492]
Bitcoin on the other hand is a transparent ledger.
[494]
At any point in time I can sneak a peek into the ledger
[497]
and see all of the transactions and balances that are taking place.
[501]
The only thing you can’t figure out is
[503]
who owns these balances and who is behind each transaction.
[507]
This means Bitcoin is pseudo-anonymous;
[510]
everything is open, transparent and trackable
[513]
but you still can’t tell who is sending what to whom.
[516]
Let’s explain this with an example.
[518]
You can see on your screen certain rows from Bitcoin’s ledger.
[522]
We can see that a certain Bitcoin address
[524]
sent 10,000 Bitcoins to another Bitcoin address
[527]
in May of 2010.
[529]
This specific transaction is the first purchase
[532]
that was ever made with Bitcoin
[533]
and it was used to buy 2 pizzas by a guy named Laszlo.
[538]
Laszlo published a post back in 2010
[540]
asking for someone to sell him 2 pizzas in exchange for 10,000 Bitcoins.
[544]
Well, someone did, and now the price of these two Pizzas
[548]
is worth well over 100 million dollars today.
[552]
Bitcoin is also decentralized;
[555]
there’s no one computer that holds the ledger.
[557]
With Bitcoin, every computer that participates in the system
[561]
is also keeping a copy of the ledger, also known as the Blockchain.
[565]
So if you want to take down the system or hack the ledger
[568]
you’ll have to take down thousands of computers
[571]
which are keeping a copy and constantly updating it.
[574]
Like most money today, Bitcoin is also digital.
[578]
This means there’s nothing physical that you can touch in Bitcoin.
[582]
There are no actual coins,
[583]
there are only rows of transactions and balances.
[586]
When you “own” Bitcoin
[588]
it means that you own the right to access
[590]
a specific Bitcoin address record in the ledger
[593]
and send funds from it to a different address.
[596]
So what does all of this mean?
[598]
Why is Bitcoin such big news?
[600]
Well for the first time since digital money came into existence
[604]
we now have an alternative to the current system.
[608]
Bitcoin is a form of money that no government or bank can control.
[612]
Think about the time before the Internet,
[614]
how centralized the flow of information was.
[617]
Basically if you wanted information
[619]
you could get it from a few major players
[621]
like the New York Times, The Washington Post
[623]
and others like them.
[624]
Today, thanks to the Internet, information is decentralized
[628]
and you can communicate and consume knowledge
[630]
from around the world with the click of a button.
[633]
Bitcoin is the Internet of money
[635]
and it’s offering a decentralized solution to money.
[639]
Bitcoin has several advantages over the current system.
[642]
First, it gives you complete control over your money.
[646]
With Bitcoin, you and you alone can access your funds.
[650]
How you actually do this will be explained in a later video.
[653]
No government or bank can decide to freeze your account
[656]
or confiscate your holdings.
[658]
Bitcoin also cuts a lot of the middlemen from the process of transferring money.
[663]
This means that in many cases
[664]
Bitcoin is cheaper to use than traditional wire transfers or money orders.
[669]
Also, unlike fiat currencies,
[671]
Bitcoin was designed to be digital by nature,
[674]
this means you can add additional layers of programming on top of it
[678]
and turn it into “smart money”, but more on that in later videos.
[682]
Finally, Bitcoin opens up digital commerce to
[685]
2.5 billion people around the world
[687]
who don’t have access to the current banking system.
[690]
These people are unbanked or underbanked
[693]
because of where they leave and the reality that they have been born into.
[697]
However, today, with a mobile phone and a click of a button
[700]
they can start trading using Bitcoin, no permission needed.
[705]
Today there are several merchants online and offline that accept Bitcoin.
[710]
You can order a flight or book a hotel with Bitcoin if you like.
[713]
There are even Bitcoin debit cards
[715]
that allow you to pay at almost any store with your Bitcoin balance.
[719]
However the road toward acceptance by the majority of the public
[722]
is still a long one.
[724]
As we continue in this video series,
[726]
we will break down exactly how Bitcoin works and how to use it.
[730]
We will learn about Bitcoin mining, Bitcoin wallets, how to buy Bitcoins
[734]
and much more.
[735]
The revolution of money began in 2009
[738]
and these days we are seeing it change money as we know it.
