3. GENERAL TERMS
1. Blockchain (balances)
2. Private keys (Transactions)
3. Mining (Processing)
4. Bitcoin space
5. Bitcoin Wallet - BTW
6. Bitcoin Exchange- BTE

4. Blockchain (balances)
The Blockchain is a shared public ledger on which the
entire Bitcoin network relies. All confirmed transactions
are included in the Blockchain. The integrity and the
chronological order of the block chain are enforced
with cryptography
This way:
• Bitcoin wallets can calculate their spendable balance
• New transactions can be verified to be spending
bitcoins that are actually owned by the spender. The
integrity and the chronological order of the block
chain are enforced with cryptography

5. Private keys (Transactions)
A transaction is a transfer of value between Bitcoin
wallets. Bitcoin wallets keep a secret piece of data
called a private key or seed, which is used to sign
transactions (=providing a mathematical proof
that they have come from the owner of the
wallet).
All transactions are broadcast between users and
usually begin to be confirmed by the network in
the following 10 minutes, through a process
called mining.

6. Mining (Processing)
Mining is a system that is used to confirm waiting
transactions by including them in the Blockchain.
Mining:
• Enforces a chronological order in the Blockchain
• Protects the neutrality of the network
• Allows different computers to agree on the state of the
system.
• Prevents any individual from adding new blocks in the
Blockchain
• Secure the element when no one can control what is
included in the Blockchain

7. Bitcoin Space (How to get in)
In and Out: Exchanges, P2P, Local Bitcoins,
ATM’s, Cash, Convenient stores, E-wallets, Value
cards, Donations, Faucets, games, etc…

8. Bitcoin Wallet - BTW
A “wallet” is Bitcoin bank account.
BTW allows you to receive bitcoins, store them, and then send them
to others.
• Software wallet is one that you install on your own computer or
mobile device. You are in complete control over the security of
your coins.
• Web wallet is hosted by a third party. They are often much easier
to use, but you have to trust the provider.
• Key Device is an external hardware or disk

9. Bitcoin Wallet - BTE
This is the safest and easiest online way in and
out to the Bitcoin space:
1. Dual or more currencies
2. Geo located in most cases
3. Can have additional crypto currencies
4. P2P / P2E

10. Blockchain.info
All information needed from the blockchain is open and available to
us all
• All Transaction per wallet, per block, etc
• Total Transactions and values
• Number of Transactions
• Estimated Transaction Volume
• Market Price
• USD volume trade
• Mining information: difficulty, revenue, etc
• Unique addresses
• News and updates

11. When you use Bitcoin
1. Securing your wallet
2. Bitcoin price is volatile
3. Bitcoin payments are irreversible
4. Bitcoin is not anonymous
5. Unconfirmed transactions aren't secure
6. Bitcoin is still experimental
7. Government taxes and regulations

12. Securing your wallet
Like in real life, your wallet must be secured.
Bitcoin makes it possible to transfer value
anywhere in a very easy way and it allows you to
be in control of your money.
• User + Pass
• IP restricted
• 2FA
• SMS Verification
• More

13. Bitcoin price is volatile
The price of a bitcoin can unpredictably
increase or decrease over a short period of
time.
$1,232-$1,262 (+3%)– How long ?

14. Bitcoin payments are
irreversible
Any transaction issued with Bitcoin cannot be
reversed, they can only be refunded by the
person receiving the funds.

15. Bitcoin is not anonymous
Some effort is required to protect your privacy
with Bitcoin. All Bitcoin transactions are stored
publicly and permanently on the network,
which means anyone can see the balance and
transactions of any Bitcoin address.
BUT, the identity of the user behind an address
remains unknown. This is one reason why
Bitcoin addresses should only be used once.

16. Unconfirmed transactions aren't
secure
Transactions don't start out as irreversible.
Instead, they get a confirmation score that
indicates how hard it is to reverse them.
Confirmation takes between a few seconds and
90 minutes, with 10 minutes being the average.

18. Bitcoin is still experimental
Bitcoin is an experimental new currency that is
in active development ( less than 6 years ).
Each improvement makes Bitcoin more
appealing but also reveals new challenges as
Bitcoin adoption grows.
Lots is happening every day, still nobody can
predict Bitcoin's future.

19. Government taxes and
regulations
Bitcoin is not an official currency. That said,
most jurisdictions still require you to pay
income, sales, payroll, and capital gains taxes
on anything that has value, including bitcoins.
Depends on the central bank and the country
adoption of the crypto technology.

20. Get educated
Crypto market is moving fast, changing fast and
new players are joining on daily basis. Don’t let it
go
