@SDWOUTERS
One of many DISRUPTIVE PLAYERS
@SDWOUTERS
“bitcoin is digital money”
Who has heard of Bitcoin before today?
Positive image? Negative image?
Who fundamentally
understands Bitcoin?

"Don't forget that the millions of people all over the world who are now part of the Bitcoin network were once very strong skeptics. This includes people with decades of experience in network security and cryptography." ~Andreas Antonopoulos

@SDWOUTERS
The first thing bought with 10.000 Bitcoins in 2010
@SDWOUTERS
Bitcoin’s best days must be over!
Is worth over €6 Million today at €600 per BTC
So much value, all for shady digital money?
@SDWOUTERS
Bitcoin challenges your understanding of money
Banks: Bitcoin can’t work, It’s all about the Blockchain
@SDWOUTERS
What’s the difference?
Bitcoin is a way to digitally transfer ownership
without a middleman
The blockchain is a database that records
ownership through time
A 5 minute explanation won’t make you understand why they matter
@SDWOUTERS
WHAT can we do with them?
HOW do they work?
WHY do Bitcoin & Blockchain
exist?
@SDWOUTERS
WHY do Bitcoin & Blockchain
exist?
@SDWOUTERS
Why do digital money transfers take days?
@SDWOUTERS
Why are digital money transfers expensive?
9% FEE?
@SDWOUTERS
Financial innovation is held back by rules and regulations@SDWOUTERS
@SDWOUTERSBut this is innovation!
Say that to the 40% unbanked adults worldwide…
And to the people who pay 5-25% money transfer fees
@SDWOUTERS
@SDWOUTERS
If you want to send money you have to
WAIT PAY
@SDWOUTERS
Yet we can do THIS?
@SDWOUTERS
@SDWOUTERS@SDWOUTERS
Bitcoin is about more than global payments
We have more debt than can EVER be repaid
@SDWOUTERS
Income inequality keeps growing
@SDWOUTERS
Nations have gold reserves that don’t exist
“There hasn’t been a comprehensive audit of Fort Knox in over 60 years.”
@SDWOUTERS
Currencies are not backed by anything
@SDWOUTERS
Leading to unprecedented money printing
@SDWOUTERS
The money in your bank loses value
Inflation Interest>
@SDWOUTERS
Soon you’ll be PAYING banks so they can do risky investments with your money
@SDWOUTERS
If finance is so messed up why don’t we fix it?
@SDWOUTERS
Governments are not in charge in the financial world
Governments
Corporates
Banks
National central banks
International central banks
Central bank of central banks
Regulation
Resulting in "cosy" relationships between financial businesses and regulators
@SDWOUTERS
@SDWOUTERS
Banks won’t stop messing around
Resulting in "cosy" relationships between financial businesses and regulators.
@SDWOUTERS
We are fighting a never ending flood
@SDWOUTERS
HOW do they work?
WHY do Bitcoin & Blockchain
exist?
@SDWOUTERS
Fundamentally different
Transactions Security
@SDWOUTERS
Transactions Security
@SDWOUTERS
Money is sent directly between two parties
@SDWOUTERS
Transactions are synchronised through the network
The blockchain is a global “bookkeeping” system
It records who owns what, and when
@SDWOUTERS
Anyone can own a copy of the Blockchain
@SDWOUTERS
@SDWOUTERS
How do we Record transactions
so nobody can change them?
@SDWOUTERS

The Blockchain is secured by computing power from people and companies all over the world
@SDWOUTERS
@SDWOUTERS
In return for their work, the miners earn new bitcoins and transaction fees
…
These “miners” verify the transactions and add them to the next block in the Blockchain
@SDWOUTERS
When you change a transaction the link to that block changes as well
@SDWOUTERS
The network will know that your version has been messed with and reject it
@SDWOUTERS
You then need to create a blockchain with more
computer power than the entire network combined
The network is 20.000 times stronger than the top 500 supercomputers in the world
@SDWOUTERS
Who decides what everyone does with their computer?

The Internet & Bitcoin
It started from the base code, ever since improvements have been proposed by developers around the world

github.com/bitcoin/bips
@SDWOUTERS
If the vast majority of the network
agrees, the code can be changed
@SDWOUTERS
What does this technical stuff mean for me?
Send & receive payments anywhere in the world
Nobody can stop it
Bitcoin is open to anyONE without identification or authentication
@SDWOUTERS
@SDWOUTERS
Governments and banks dislike…
because they have less control over us. They can't track what
we do with it, so people can use it for illegal activities.
CASH
because they have no control. They can track exactly what we
do with it, but we would also see what they do…
BITCOIN
Which is exactly what happened
theguardian.com/us-federal-agent-investigating-silk-road-admits-800000-bitcoin-theft
What criminal leaves permanent evidence?
@SDWOUTERS
@SDWOUTERS
Should we have forbidden these too because criminals can use them?
Technology always reflects society
Anyone can develop new applications for Bitcoin, without permission
@SDWOUTERS internetlivestats.com/internet-users/
The same force driving internet innovation for 20 years
@SDWOUTERS
Creates huge value for consumers, economic growth, jobs
I don’t really need Bitcoin
Until your life is international
Transferred money with a large fee or terrible exchange rate?
Have you ever…
Tried to understand why these transfers take days?
Paid fees or exchange rates at ATM’s or with your card abroad?
Have you ever been to a country where the majority of the population is unbanked?
Have you ever met people who cannot use their debit or credit cards abroad?
Exchanged money on the black market?
Returned home with leftover foreign currency?
@SDWOUTERS
Dealt with currency controls?
Or Hyperinflation?
@SDWOUTERS
Soon you’ll be PAYING banks so they can do risky investments with your money
@SDWOUTERS
Perhaps you & your country don’t really need it…
But it will help the world a lot if Bitcoin succeeds.

@SDWOUTERS
@SDWOUTERS
‣ Bitcoin is only 7 years old, it still needs a lot of development.
‣ We have never tried THIS before and it is about MONEY, not info.
‣ It’s like the Internet in the 90s:
‣ People don't get it. ‣ It looks ugly. ‣ We have few use cases. ‣ People don’t see how it will
change the world. ‣ Those who are disrupted by it
will do everything to stop it. ‣ Mainstream 10 years later ‣ Mass adoption 20 years later
