What is Bitcoin?

Simple Definition

Bitcoin is a decentralized digital currency that allows value transfers over the internet without the need for intermediaries like banks.

In simpler terms: Bitcoin is digital money that works over the internet. You can use it to buy things, send to other people, or store as an investment.

Main Characteristics

1. Digital:

Bitcoin exists only digitally
There are no physical coins or bills
Everything is stored and transferred over the internet

2. Decentralized:

No central bank controlling it
No government or company behind it
Network maintained by thousands of computers around the world

3. Peer-to-Peer (P2P):

You can send directly to another person
No need for intermediary
Like sending physical money, but over the internet

4. Limited:

There will be at most 21 million Bitcoins
Scarcity controlled by code
Similar to gold (limited resource)

5. Transparent:

All transactions are public
Anyone can see the history
But identities are private (pseudonyms)

Why Was Bitcoin Created?

Bitcoin was created in 2009 by a person (or group) using the pseudonym Satoshi Nakamoto, in response to the 2008 financial crisis. The idea was to create a financial system that:

Didn't depend on banks or governments
Worked without trusting intermediaries
Was transparent and verifiable
Allowed direct transactions between people
Had fixed and predictable rules

Bitcoin vs Traditional Money

Traditional Money (Dollar, Euro, etc.):

Controlled by government/central bank
Can be printed without limit
Depends on banks for transfers
Transactions can be tracked and blocked
Limited operating hours

Bitcoin:

Not controlled by anyone
Limited quantity (21 million)
Direct transfers, no banks
Pseudonymous (not fully anonymous)
Works 24 hours a day, 7 days a week

Is It Real Money?

Bitcoin can be used as money because it has three important characteristics:

Store of value: You can store it and value is maintained (or may increase/decrease)
Medium of exchange: You can use it to buy things (where accepted)
Unit of account: You can measure value in Bitcoin

However, it's still not widely accepted as a form of payment. Many people use it mainly as an investment or store of value.

How Does Bitcoin Work?

Basic Concepts

Blockchain (Chain of Blocks):

It's a digital record book
All transactions are recorded here
It's public and verifiable by anyone
Blocks are linked in sequence (like a chain)

Mining:

Process that validates transactions and creates new Bitcoins
Miners solve complex mathematical problems
First one to solve wins Bitcoin reward
Ensures network security

Private and Public Keys:

Public key: like your email address (can share)
Private key: like your password (NEVER share!)
Private key controls your Bitcoins
Whoever has private key controls the funds

Wallets:

Programs or devices that store your keys
Allow sending and receiving Bitcoin
Don't store Bitcoin itself, store keys that give access

How Transactions Work

Simplified process:

You want to send Bitcoin: Open your wallet and create transaction
Transaction is announced: Goes to Bitcoin network (mempool)
Miners validate: Verify if you have enough Bitcoin
Block is created: Transaction is included in a block
Block is added: Goes to blockchain permanently
Transaction confirmed: Recipient receives Bitcoin

Average time: 10 minutes for first confirmation (varies)

Why Is It Secure?

Cryptography:

Uses advanced mathematics for protection
Private keys are practically impossible to guess
Transactions are mathematically verified

Decentralization:

No single point of failure
Many computers maintain copy of blockchain
Makes attacks difficult

Proof of Work:

Attacks would cost billions in energy
It's cheaper to play honestly
Economics protects the network

How to Buy Bitcoin?

Where to Buy

1. Exchanges:

Online platforms to buy/sell Bitcoin
Easiest for beginners
Examples: Coinbase, Binance, Kraken
Allows buying with card or bank transfer

2. P2P (Peer-to-Peer):

Direct purchase from another person
Exchange facilitates connection (but not intermediary)
More control, but more care needed

3. Bitcoin ATMs:

Physical machines where you insert money
Receive Bitcoin in wallet
Usually have high fees

For beginners: Start with exchange. It's easier and safer.

Step-by-Step: Buying on Exchange

1. Choose an Exchange:

Research trustworthy exchanges
Check if regulated
See reviews and history
For U.S. users: prefer regulated exchanges

2. Create Account:

Access exchange website
Fill in basic data (name, email, password)
Create strong and unique password

3. Verify Your Identity (KYC):

Send documents (ID, proof of address)
Take selfie (some exchanges request)
Wait for approval (can take hours or days)

4. Make Deposit:

Connect bank account or card
Make deposit (bank transfer, card)
Wait for confirmation (usually fast)

5. Buy Bitcoin:

Go to "Buy" or "Trade" area
Choose amount in dollars
Confirm purchase
Bitcoin will appear in your account

6. Store or Transfer:

Leave on exchange (easier, less secure)
Transfer to personal wallet (more secure)

Payment Methods

Bank Transfer:

Fastest in U.S. (minutes to hours)
Usually no fee
Ideal for deposits

Debit/Credit Card:

Faster
Usually higher fee
Some exchanges don't accept

Wire Transfer:

Slower (can take days)
Usually no fee
Less used today

How Much to Buy?

Tip for beginners:

Start small ($20, $50, $100)
Learn to use first
Increase gradually
Only invest what you can lose

Don't buy everything at once:

Consider DCA (Dollar-Cost Averaging)
Buy regularly small amounts
Reduces risk of buying at peak

Fees When Buying

Types of fees:

Deposit fee: to put money on exchange
Trading fee: when buying/selling Bitcoin
Withdrawal fee: to withdraw money
Withdrawal fee: to transfer Bitcoin to wallet

How to reduce:

Compare exchanges
Use bank transfer (usually no deposit fee)
Avoid credit card (higher fee)
Keep on exchange for a while before transferring (reduces transfers)

How to Store Bitcoin?

What is a Wallet?

Bitcoin wallet is a program or device that stores your private keys and allows sending/receiving Bitcoin.

Important: wallets don't store Bitcoin itself. Bitcoin exists on the blockchain. Wallets store the keys that give access to your Bitcoins.

Types of Wallets

1. Custodial Wallets (Exchange):

Exchange stores your keys
You don't fully control
Easier, less secure
Good for beginners to start

Advantages:

Very easy to use
Don't need to worry about backup
Quick access

Disadvantages:

Exchange controls your keys
If exchange is hacked, you may lose
"Not your keys, not your Bitcoins"

2. Hot Wallets:

Connected to internet
More convenient
Less secure than cold

Examples:

Mobile apps (e.g., Trust Wallet, BlueWallet)
Browser extensions (e.g., MetaMask)
Software on computer (e.g., Electrum)

For beginners: Mobile apps are easier.

3. Cold Wallets:

Not connected to internet
More secure
For larger amounts

Examples:

Hardware wallets (e.g., Ledger, Trezor)
Paper wallets
Wallets on offline computer

For beginners: Consider after gaining more experience.

Wallets for Beginners

Recommendations to start:

1. Exchange (to start):

Use to buy and learn
Transfer to personal wallet later
Don't store large amounts for long time

2. Mobile App (next step):

Easy to use
Always with you
Good for small amounts
Examples: Trust Wallet, BlueWallet, Exodus

3. Hardware Wallet (when you have more):

More secure
For larger amounts
Requires more knowledge
Examples: Ledger Nano, Trezor

Seed Phrase (Recovery Phrase)

What it is:

List of 12 or 24 words that give access to your wallet
Like master password
Whoever has seed phrase has access to your Bitcoins

VERY IMPORTANT:

Write on paper
Store in safe place
NEVER share with anyone
NEVER type on public computers
Make copy and store in different place

If you lose seed phrase:

You lose access to your Bitcoins
No way to recover
It's permanent

How to store:

Write on paper (don't print)
Store in safe or secure location
Make copy in different location
Consider metal plate (fire/waterproof)

How to Transfer Bitcoin to Wallet

Process:

Install wallet: Download app or software
Configure wallet: Create new wallet
Write seed phrase: Write on paper and store
Copy address: Receiving address of wallet
Go to exchange: Go to "Withdraw" or "Send"
Paste address: Paste your wallet address
Confirm amount: Choose how much to send
Confirm send: Review everything before confirming
Wait for confirmation: May take 10-30 minutes

Important tips:

Test first with small amount
Always verify address (first and last characters)
Confirm it's Bitcoin network (not another blockchain)
Never send Bitcoin to address of another currency

How to Send and Receive Bitcoin?

How to Receive Bitcoin

1. Get Your Address:

High fee: faster (10 minutes)
During congestion, fees may be high

5. Review and Confirm:

Verify address again
Verify amount
Verify fee
Confirm send

6. Wait for Confirmation:

Transaction goes to mempool
Wait to be included in block
After confirmations, recipient receives

Transaction Fees

What they are:

Paid to miners to include transaction in block
Not fixed, you choose how much to pay
The more you pay, the faster it confirms

How they work:

Low fee: may wait hours or days
Medium fee: usually confirms in 10-30 minutes
High fee: confirms in ~10 minutes
During congestion, need to pay more

How to save:

Don't send during peak hours

All work, but some have lower fees

Important:

Always verify address before sending
Wrong address = permanent loss
Can have multiple addresses
Addresses are reusable, but better to create new ones

Confirmations

What they are:

Each time block is added after your transaction = 1 confirmation
More confirmations = more secure
After 1 confirmation, usually safe
After 6 confirmations, very safe

Why it matters:

Protects against transaction reversal
More confirmations, harder to reverse
For small amounts: 1 confirmation is enough
For large amounts: wait 3-6 confirmations

Time:

Frequently Asked Questions

Do I need to buy a whole Bitcoin?

No. You can buy fractions of Bitcoin. For example, you can buy 0.001 Bitcoin. The smallest unit is the satoshi (0.00000001 Bitcoin).

Will Bitcoin go to zero?

It's possible, but unlikely considering its growing adoption. Bitcoin is a risky investment - can lose value, but can also gain a lot.

Can I lose my Bitcoins?

Yes, if you lose your seed phrase or send to wrong address. That's why security is so important.

Is Bitcoin anonymous?

Not completely. Transactions are public, but identities are pseudonymous. Not fully anonymous like physical cash.

Do I need to mine Bitcoin?

No. You can just buy. Mining is for people/companies with specialized equipment.

How much do I need to start?

You can start with any amount ($20, $50, $100). Don't need much to learn.
