We will discuss...
• What is money?
• What is Bitcoin?
• What makes bitcoin a different kind of money?
• How does bitcoin work? (micro + macro)
• Fresh numbers from the bitcoin economy
• Why bitcoin is so good, that it simply can’t fail
• Why bitcoin can fail
• The State of the Industry

3.
Let’s talk about money first
• Money is a medium to store and exchange
economic value
• Was invented to replace barter (inefficient)
• Money can be exchanged for goods and services (including
other money)
• Historic examples: shells, boards, gold
• 7 things that a good currency must be:
• Acceptable, Divisible, Durable, in limited supply, Portable,
Uniform, Stable

4.
Let’s talk about money first (Cont.)
• Value of a currency: balance between supply and
demand
• Does money come with guarantee of value?
• Strong guarantee: intrinsic (Gold)
• Medium guarantee: convertible into a resource with intrinsic
value (old USD -> Gold)
• Low guarantee (“Fiat money”): USD, EUR, AUD, CAD,
bitcoin?

5.
What is Bitcoin?
• Bitcoin (BIG B) is the technology
• “bitcoin” (little b) is the (token)
• Currently it is only the first wave of
innovation coming from the technology

6.
bitcoin is?
• From the Washington Post:
“bitcoin is: an electronic cash system that allows online
payments to be sent directly from one person to another
without going through a financial institution (like a bank) or a
third party (like PayPal).”
• It has (almost) all the properties of a
good currency
• The Problem of Double Spending
Solved

7.
But it’s a different kind of token
What makes it different?
• It’s completely digital (owning bitcoin is owning a private key)
• It’s completely decentralized and not owned by anyone (company,
country)
• It’s based on open sourced software and an open network
• It was started by an anonymous entity (Satoshi Nakamoto, 2008)

8.
Micro: how do you use bitcoin?
• Install an open source wallet software (or choose an online
wallet)
• The wallet will create:
• Your address: 13v8NB9ScRa21JDi86GmnZ5d8Z4CjhZMEd
• Your private key:
5KJvsngHeMpm884wtkJNzQGaCErckhHJBGFsvd3VyK5qMZXj3hS
• Receiving bitcoin is like receiving email: just give your
address to someone else
• Sending bitcoin is like sending email: just put the recipient’s
address, choose amount and press “send”
• How to buy bitcoin in the first place?

9.
Macro: bitcoin in numbers
• BTC/USD rate: 230 USD
• Total bitcoins today: ~14.5M
• Market cap today: ~3.3 bn USD
• Total bitcoins wallets (accounts): 3.5M~ (source: Tim Swanson)
• bitcoin transactions daily: 85-107k (100k-200k BTC, 50-100M
USD)
• Businesses accepting bitcoins globally: ~100k
• You can divide 1 bitcoin down to the level of 0.00000001 BTC
• Investor-backed bitcoin companies raised $375 million in 52 deals
between January and June of 2015

bitcoin just can’t fail #1
“The big 5” trillion-dollar economies that don’t like
bitcoin:
1. Credit cards: bitcoin has very low (close to zero)
transaction fees (CC: min $0.2 + 2-3%)
2. Micropayments: bitcoin is micropayments-ready
3. Banking & Financial Inclusion: half of the world
doesn’t have a bank account
4. Money remittance
5. Gold

11.
bitcoin just can’t fail #2
• It’s anonymous (sort of)
• It’s inflation free (21M BTC in circulation by 2140- that’s it)
• It has no single point of failure (banking system,
countries)
• It’s international (globalization-ready)
• Chargebacks will be more rare (transactions are
irreversible but third party will provide services & off-chain
transactions)
• It publishes its entire history (easier to track)
• It’s innovation-ready (transparency & protocol)

12.
Well, actually bitcoin can fail
• PKI cryptography could get hacked (very
unlikely)
• Private keys could get hacked (quite likely)
• Countries and regulators
• Can be used for illegal activity
• Affects taxing, consumer protection, AML
laws

13.
Well, actually bitcoin can fail (cont.)
• Consumers & merchants
• Software is clumsy and hard to use
• Considered too risky, unstable or “just a Ponzi
scheme”
• Crazy volatility (BTC/USD rate) and high
sensitivity
• Exchanges halts or closes and “bitcoins lost”
• Apple takes blockchain.info wallet off the AppStore
• Regulation talks
• We don’t know what we don’t know

14.
The State of the Industry
bitcoin Scalability
Hardware Wallets
The Blockchain

15.
bitcoin Scalability
Core change to the design blueprint or hard fork
is needed
• Permanently keeping the 1MB (anti-spam) restriction is a
great idea, if you are a bank since it keeps it at 2 to 4
transactions per second (tps)
• VISA alone does 2,000 tps on average
Agreement is that the block size has to be
increased

16.
bitcoin Scalability (cont.)
Long term there is: The Bitcoin Lightning Network
A decentralized system whereby transactions are sent over
a network of “payment channels” whose transfer of value
occurs off-blockchain
Bitcoin transactions may occur between untrusted parties
and secured by the bitcoin blockchain

17.
Hardware Wallets
Manage private key generation, private key
storage, and transaction signing.
Examples:
The Ledger Wallet
keepkey
Trezor wallet
“Hardware devices like the TREZOR that cannot be infected by
malware will make holding bitcoins as easy and secure as holding
paper money. They are an exciting step in the evolution of Bitcoin
from an experiment for geeks to a payment system anybody can
use.” - Gavin Andresen

18.
The Blockchain
Blockchain 2.0 Other applications (Utilities)
● Distributed fair voting
● Stock ownership
● Asset registration and notarization
● Smart Property
● And others we have not thought about

startups.” -Forbes
Banking Superpowers Unite Behind Bitcoin’s
Blockchain Tech -The Cointelegraph
Goldman Sachs, Barclays, J.P. Morgan Chase,

“First Global Credit CEO Gavin Smith Goes on the
Record About Bitcoin’s Coming of Age” -Coinbase
“Traditional financial products and instruments
need to be offered through the medium of
bitcoin to advance the transition of bitcoin from
early adopter novelty to a fully integrated part of
the world financial ecosystem.” Says Smith
