WHAT THE FAMOUS THINK
“Cryptocurrencies are used for buying Fentanyl and other drugs so
it is a rare technology that has caused deaths in a fairly direct way.
I think the speculative wave around ICOs and cryptocurrencies is
super risky for those who go long,” “Yes, anonymous cash is used
for these kinds of things but you have to be physically present to
transfer it which makes things like kidnapping payments more
difficult.”
Tesla CEO Elon Musk recently made a statement that his piggy
bank has a very modest stock of cryptocurrency – only 0.25
BTC. But asking what can be done with Ethereum.

WHAT IS A CRYPTO-CURRENCY
No CEO
No frontier
Open source
Systematically under attack
No company
Rare – Not rare
Trusted or Untrusted
No brand
Bad publicity
Peer to Peer
No single point of failure
Near anonymity
DEFINITION OF VIRTUAL CURRENCY
In 2014, the European Bank Authority defined virtual currency as :
“A digital representation of value that is neither issued by a central bank or a public
authority, nor necessarily attached to a fiat currency, but is accepted by natural or
legal persons as a means of payment and can be transferred, stored or traded
electronically.”

CRYPTO-CURRENCY : ANONYMITY V/S PRIVACY
1. A transaction is “anonymous” if no one knows who you are.
2. A transaction is “private” if what you purchased & for what amount, are unknown

FACEBOOK AND CRYPTOCURRENCIES
Facebook’s cryptocurrency secretive plan : GlobalCoin FB Coin, or Libra
 Help Facebook develop an entirely new revenue stream aside from advertising.
 Zuckerberg met with Central Bank of England Governor, MasterCard, Visa,
Western Union,...
 As much as $19 billion in additional revenue in its “upside case” for Facebook
by 2020 if its secretive cryptocurrency plans work out.
 Launched in around 12 countries.
 Conservatively, an incremental $3 billion in revenue from a successful
cryptocurrency implementation.
 Developing a cryptocurrency to use for peer-to-peer payments, tied to the value
of traditional currencies and available to use through WhatsApp
 Stablecoin : would likely be less attractive to and targeted by speculators, such
as hedge funds, because of its fixed price tied to a currency like the U.S. dollar.
 Facebook will want to be in control to gather data and simplify administration.

CRYPTOCURRENCIES – HOW TO TRADE
Through the sections :
1. Fiat to Crypto Trading.
2. Storing Cryptocurrencies.
3. Crypto to Crypto Trading.
HOW TO TRADE
Fiat to Crypto :
1. You have money to invest.
2. Chose an exchange :
 Make sure that the exchange / trader is available / allowed in Lebanon.
 Check reputation
 Check exchange rates
 Check required documents / safety
3. Create an account.
4. Wallet :
 You must have one.
 Cryptocurrencies deposited in & protected by a wallet.
 It saves your private and public keys which helps you store, send, and
receive cryptocurrencies.
5. Private key :
 Gives you the right to access and send money.
 Confidential and private.
6. Public key :
 The address where everyone will send you money.
 Public, to be given to others.

18.
HOW TO TRADE
Storing your Crypto :
1. Hot storage.
2. Cold storage.
Hot storage :
1. Like the wallet you carry around in your pocket.
2. It gives you easy access to your cash.
3. But, it is pretty vulnerable.
Cold storage :
1. Like your savings account.
2. Highly impractical for day-to-day use.
3. But, extremely safe.
HOW TO TRADE – CRYPTO TO CRYPTO
1. Open accounts in exchanges that enables crypto-to-crypto trading.
2. Check what cryptocurrencies are accepted, some allow you to buy using
Bitcoin only.
3. Preferably better different than the one used to buy crypto from fiat.
4. Like traditional fiat currencies trading, with its charts, indicators,…

POSSIBLE FUTURE OF CRYPTO-CURRENCIES - BITCOIN
What to expect ?
By following the pattern :
 Rise in November 2021
 By 1,300%
 Value ~40k$
 Market capitalization : ~800B$.
 Nothing compared to the dot.com bubble in 2001 of 9.6T$.

20.
POSSIBLE FUTURE OF CRYPTO-CURRENCIES - BITCOIN
Near anonymity :
 Take it away and no one will want to use it;
 Keep it and advanced-economy governments will not tolerate it.
Other see it more likely at ~100$.
Bitcoin is like lottery tickets that might pay off in future
Many crypto-evangelists insist that bitcoin is “digital gold,” in part because the long-
term supply is algorithmically capped at 21 million.
Unlike gold – which has always had other purposes and today is employed widely in
new technologies from iPhones to spacecraft – bitcoin has no alternative use. And even
if bitcoiners manage to find a way to lower the phenomenal energy cost of verifying
transactions, the very nature of decentralised ledger systems makes them vastly less
efficient than systems with a trusted central party like a central bank.
Real question : if and when global regulation will stamp out privately constructed
systems that are expensive for governments to trace and monitor.
In the end, advanced economies will surely coordinate on cryptocurrency regulation, as
they have on other measures to prevent money laundering and tax evasion.

POSSIBLE FUTURE OF CRYPTO-CURRENCIES - BITCOIN
This 10-years old technology pretends to replace the 4,000 years old fiat
currency.
POSSIBLE FUTURE OF CRYPTO-CURRENCIES – COUNTRIES
The Banque du Liban closing in on the launch of its own crypto-currency.
Launch of a new 100% ‘made in Lebanon’ crypto-currency in the near future.
The currency will be a “virtual Lebanese pound” destined exclusively for local use.
Its goal is to ease payment methods, to implement a technological transformation of
financial institutions and to lower the costs borne by consumers.
However, many risks have still to be taken into consideration.
First off, there are concerns about money laundering and cyber security.
Lebanon was the first country in the Middle East to issue an official warning regarding
their trade.
Tunisia has already launched its e-DINAR in 2015, followed by the e-CFA in Senegal at
the end of 2016, both based on blockchain technology.
Other states are in a trial phase such as Uruguay, Dubai with its emCash, Iran, which is
looking to bypass American sanctions, and Singapore.
The Swiss company X8 has received a “sharia-compliant” certificate awarded by the
Shariyah Review Bureau for its “stablecoin”.

CONCLUSION
Hoaxor
 Some see them disappear.
 Some see them replacing national currencies by 2030.
 Only the future will tell us, most probably they are here to stay.
 A lot of them will disappear.
 New ones will be created.
 They will play a role in the world economy.
 Interesting to follow them up and understand :
 Their evolution
 Their weaknesses and strengths
 The regulations.
 Be cautious (if you want to invest) :
 Don’t bet on risky / dark crypto-currencies, even if they have a high ROI.
 Chose more stable ones with a clear purpose and objective.

 1991 :
o Idea behind blockchain technology traced back.
o Stuart Haber and W. Scott Stornetta described the first work on a
cryptographically secured chain of blocks.
 1992 :
o They incorporated the capability of collecting several documents into a block.
 2008 :
o Satoshi Nakamoto published the Bitcoin white paper.
o Blockchain technology as we know it today gained then significance.
WHO IS BEHIND IT

24.
WHO USE IT - SECTORS
TECHNOLOGY BEHIND : BLOCKCHAIN
Internet most
promising new
development
One of the most
important
technologies to
emerge in recent
years
The applications
for blockchain
technology seem
endless
It will change our
world in the next
two decades as
much as the
Internet has over
the last two ones
It can also solve problems
and create new
opportunities in health
care, defense, supply
chain management,
luxury goods,
government, and other
industries
Businesses can use
it to streamline
operations and
create new
opportunities

25.
The technology could
give rise to what
Gartner calls “the
programmable
economy”, powered
by entirely new
business models that
eliminate all kinds of
middlemen
Machine networks in which devices engage in economic
activity, and “smart assets” in which some form of
property such as shares in a company can be traded
according to programmable or artificial intelligence-based
rules rather than the control of a centralized entity.
The 1st obvious ones are
financial : international
payments, remittances,
complex financial
products
It will offer trust to financial services.
It will be a business enabler.
WHAT DO THEY SAY ABOUT IT
It is a distributed ledger of all transactions across a peer-to-peer network.
No need for central certifying authority to confirm transactions.
What is it ?
A blockchain is a single version of the truth made possible by an immutable and
secure time-stamped ledger, copies of which are held by multiple parties.
It’s a secure, tamper-proof ledger with time-stamped transactions, distributed
amongst a number of entities.
The blockchain is intended to provide a tamperproof record of transaction metadata,
regardless of transaction type.
Bitcoin uses blockchain technology but it is not blockchain.
WHAT IS BLOCKCHAIN

26.
Cryptography secures the data and new transactions are linked to previous ones,
making it near-impossible to change older records without having to change
subsequent ones.
And because multiple “nodes” (computers) run the network, one would need to gain
control of more than half of them in order to make changes.
Transactions are batched together in a block.
Blocks are chained to preserve the temporal order.
Chaining is secure because each record depends on the previous ones.
How it works ?

HOW IT WORKS
Data
 Its content depends on the type of the blockchain
 Example of bitcoin blockchain :
o From

o Amount
Hash :
 Calculated once the block / data is created
 It is always unique
 It is like a fingerprint
 If the content is changed, the hash is changed.
 Example : e2c521bc53bb5db4c04aa497dba2ba5d48c8444db3
Hash of previous block :
 It helps create the chain

The principles of blockchain are important
Have the right team in place – most important factor
Picking the right technology – new & still immature technology :
 Faces many challenges
 Lack of qualified & experienced resources
Blockchain projects are complicated
 Follow best practice
 Dedicated project manager
 Agile : the most used methodology
Training : take time to learn and understand the technology & how it can be applied
User experience can be a killer regardless the technology underneath
Legal & compliance issues

Blockchain is seen as a threat to cloud computing.
Quantun computing is seen as a threat to blockchain.
Security :
 Cryptography will play a very important role.
 Access
 Identity
 Transparency & openness
 Integrity will be safeguarded
Blockchain is being increasingly used, but it not a magic bullet for everything.
It will definitely change economy, business and how things are being done
CONCLUSION
ICO – INITIAL COIN OFFERING
 ICO = crypto-equivalent of the IPO (Initial Public Offering).
 Purpose is to raise capital : digital proprietary tokens are sold.
 Quantity of cryptocurrency is sold in the form of "tokens"
to speculators or investors,
 No shares, no diligence, simply sell tokens which provide no ownership
rights or control.
 White paper with business plan for the company.
 No need to go to a bank or venture company (VC).
 Tokens are listed via cryptocurrency exchanges.
 Short period for getting the funds.
 It is a source of capital for start-ups.
 1st ICO = MasterCoin in 2012 or 2013 (depending on source).
 Ethereum raised money with a token sale in 2014, raising 3,700 BTC in
its first 12 hours, equal to approximately $2.3 million at the time.
 Feb. 2018 = Ethereum is the leading blockchain platform for ICOs (80%
marketshare)
