Welcome to Day 3 of the 365-Day Crypto Trading Guide
Welcome to Day 3 of our 365-Day Cryptocurrency Trading Guide.
In Day 1, we learned the basics of cryptocurrency and blockchain.
In Day 2, we studied Bitcoin, including Bitcoin's blockchain, mining, supply, halving, wallets, and basic BTC trading concepts.
Today, we are moving to another major cryptocurrency:
What Is Ethereum?
Ethereum is a decentralized blockchain network designed to support programmable applications, smart contracts, and digital assets.
Its native cryptocurrency is called Ether, with the ticker symbol ETH.
Bitcoin is primarily known for decentralized digital money and a scarce monetary asset.
Ethereum expanded the blockchain concept by allowing developers to create programmable applications that operate on a blockchain.
This difference is one of the most important things beginners should understand.
What Is ETH?
ETH is the native cryptocurrency of the Ethereum network.
You may see it written as:
Ethereum = Network
Ether = Cryptocurrency
ETH = Ticker symbol
ETH is used within the Ethereum ecosystem for various purposes, including paying transaction fees and participating in network activities.
ETH is also widely traded on cryptocurrency markets.
Who Created Ethereum?
Ethereum was proposed by Vitalik Buterin and developed with contributions from a broader group of developers and contributors.
The Ethereum network launched in 2015.
Unlike Bitcoin, Ethereum was designed from the beginning to support programmable blockchain applications.
Why Was Ethereum Created?
Bitcoin demonstrated that blockchain technology could support decentralized digital money.
Ethereum took the idea further.
The Ethereum network was designed to provide a platform where developers could build applications that use blockchain-based rules and smart contracts.
These applications can include:
Decentralized finance
NFT applications
Blockchain games
Decentralized exchanges
Token systems
Governance systems
Other decentralized applications
This makes Ethereum more than simply a cryptocurrency.
What Is a Smart Contract?
A smart contract is a program deployed on a blockchain that can automatically execute according to predefined rules.
Think of a smart contract as a digital agreement whose logic is written into computer code.
For example, a smart contract might be designed so that:
If condition A happens → perform action B.
The actual logic depends on how the contract was programmed.
Smart contracts are powerful, but they are not automatically safe.
A programming error or vulnerability can create serious risks.
Simple Smart Contract Example
Imagine a simple blockchain-based application.
A user deposits a certain amount of digital assets into a smart contract.
The contract follows programmed rules to determine what happens next.
There may be no traditional employee manually processing every transaction.
Instead, the blockchain network processes transactions according to the contract's code and network rules.
This is one reason Ethereum became important to the development of decentralized applications.
What Are Decentralized Applications?
Decentralized applications are commonly called dApps.
They use blockchain networks and smart contracts to provide certain functions.
Examples of areas where dApps can exist include:
Finance
Gaming
Collectibles
Trading
Lending
Borrowing
Governance
Digital identity
Not every application described as decentralized has the same degree of decentralization.
Always research a project before interacting with it.
What Is Ethereum Gas?
One of the most important Ethereum concepts for beginners is gas.
Gas refers to the computational work required to execute transactions and operations on the Ethereum network.
Users pay transaction fees for this activity.
Ethereum transaction fees are commonly referred to as gas fees.
The amount paid can vary depending on network activity and the complexity of the transaction.
Why Do Ethereum Gas Fees Change?
Ethereum gas fees can increase when network demand becomes high.
Imagine a road.
When only a few cars are using it, traffic is low.
When thousands of cars arrive at the same time, congestion increases.
Blockchain networks can experience a similar effect.
When many users are competing to have transactions processed, fees can change.
Therefore, before making an Ethereum transaction, always check the expected network fee.
What Is Ethereum's Consensus Mechanism?
Ethereum currently uses Proof of Stake (PoS).
This differs from Bitcoin's Proof of Work system.
Under Proof of Stake, participants known as validators help secure and operate the network by staking ETH according to Ethereum's protocol.
What Is Ethereum Staking?
Ethereum staking involves committing ETH to participate in network validation under Ethereum's Proof of Stake system.
In return, validators can potentially receive protocol rewards.
However, staking is not the same as guaranteed passive income.
There are technical, market, operational, and protocol-related risks.
The value of ETH can also fall even if staking rewards are being earned.
Ethereum vs Bitcoin
This is one of the most common questions beginners ask.
| Feature | Bitcoin | Ethereum |
|---|---|---|
| Main asset | BTC | ETH |
| Launch | 2009 | 2015 |
| Main concept | Decentralized digital money | Programmable blockchain |
| Consensus | Proof of Work | Proof of Stake |
| Smart contracts | Limited compared with Ethereum | Major feature |
| dApps | Not its primary purpose | Major ecosystem |
| Supply design | Maximum supply around 21 million BTC | Different monetary design |
| Gas | Bitcoin transaction fees | Ethereum gas fees |
This is a simplified comparison.
Bitcoin and Ethereum are both important blockchain networks, but their designs and purposes are different.
Is Ethereum a Cryptocurrency?
Yes.
ETH is a cryptocurrency.
However, Ethereum itself refers to the blockchain network and ecosystem.
A simple way to remember it is:
Ethereum = Blockchain network
ETH = Native cryptocurrency
What Is an ERC-20 Token?
ERC-20 is a commonly used technical standard for fungible tokens on Ethereum.
Many crypto projects have created tokens using Ethereum's token standards.
This means Ethereum can host many different digital assets in addition to ETH.
For example, a token may represent:
Utility
Governance
Access
Digital assets
Other functions
However, simply being an Ethereum token does not mean a project is trustworthy.
What Are NFTs?
NFT stands for Non-Fungible Token.
Unlike interchangeable units of a currency, NFTs are designed to represent unique digital items or records.
NFTs have been used for:
Digital art
Collectibles
Gaming items
Memberships
Tickets
Digital ownership systems
The value of an NFT can be highly speculative.
What Is DeFi?
DeFi stands for Decentralized Finance.
It refers to blockchain-based financial applications that aim to provide functions such as:
Trading
Lending
Borrowing
Liquidity provision
Asset management
Ethereum has historically been one of the major platforms for DeFi applications.
However, DeFi can involve smart-contract risk, liquidity risk, market risk, and other technical risks.
How Does ETH Get Its Value?
ETH's market price is influenced by many factors.
These include:
Supply and demand
Ethereum network activity
Market sentiment
DeFi activity
Developer adoption
Network usage
Competition
Regulation
Broader crypto-market conditions
Bitcoin's price movement
Macro-economic conditions
No single factor can reliably predict the future price of ETH.
Ethereum Trading
ETH is widely traded in cryptocurrency markets.
A beginner may encounter trading pairs such as:
ETH/USDT
ETH/USD
ETH/BTC
ETH/USDC
For example:
ETH/USDT
means the market is showing the price of ETH relative to USDT.
What Is ETH Spot Trading?
Spot trading means buying or selling ETH in the spot market.
For example, suppose ETH is trading at a hypothetical price of:
$3,000
A trader purchases ETH.
If ETH later rises to:
$3,300
the position has increased in value before considering fees and taxes.
If ETH instead falls to:
$2,700
the position has lost value.
This simple example demonstrates why trading always involves risk.
ETH Market Order
A market order attempts to execute immediately at available market prices.
The actual execution price may differ from the displayed price because of:
Market movement
Liquidity
Order-book conditions
Slippage
ETH Limit Order
A limit order allows a trader to specify the price at which they are willing to buy or sell.
For example:
ETH current price: $3,000
You might place a hypothetical buy limit order at:
$2,900
If the market never reaches $2,900, the order may remain unfilled.
ETH Futures Trading
ETH can also be traded through futures and other derivatives.
These products can allow traders to speculate on price movements without directly holding ETH in the same way as spot trading.
Futures can involve leverage.
For beginners, this creates additional risks such as:
Liquidation
Margin requirements
Funding costs
Rapid losses
Emotional pressure
Understanding spot trading and risk management should come before experimenting with leveraged products.
What Is ETH Leverage?
Leverage allows traders to control a position larger than the amount of capital deposited as margin.
For example, using hypothetical 5× leverage means:
₹10,000 margin → approximately ₹50,000 notional position.
But if the market moves against the position, losses can also increase rapidly.
Leverage is not free buying power.
It is a risk multiplier.
Ethereum Technical Analysis
Traders may use technical analysis to study ETH price behavior.
Common tools include:
Support and Resistance
Identify areas where buying or selling pressure has previously appeared.
Moving Averages
Used to study trends.
RSI
Used to analyze momentum.
MACD
Used to study momentum and trend relationships.
Volume
Used to analyze market participation.
Fibonacci Retracement
Used by some traders to identify potential retracement zones.
No indicator guarantees the next price movement.
Ethereum Market Structure
Before using indicators, learn basic market structure.
Uptrend
A series of higher highs and higher lows.
Downtrend
A series of lower highs and lower lows.
Range
Price moves between relatively defined support and resistance zones.
Understanding market structure can help you avoid relying entirely on indicators.
Example ETH Trading Setup
Let's use a hypothetical example.
Suppose:
ETH Entry = $3,000
Planned stop:
$2,900
Potential target:
$3,200
Risk per ETH:
$3,000 − $2,900 = $100
Potential reward:
$3,200 − $3,000 = $200
Planned reward-to-risk ratio:
$200 ÷ $100 = 2:1
This example does not predict that ETH will reach $3,200.
It simply demonstrates how a trader can define risk and reward before entering a trade.
Ethereum Position Sizing
Suppose your hypothetical trading account contains:
₹50,000
You decide your maximum planned loss on one trade is:
1%
Maximum planned loss:
₹500
Your position size should then be calculated according to the distance between your entry and invalidation/stop level.
This approach helps prevent one trade from causing an unnecessarily large portion of your account to be lost.
Common Ethereum Trading Mistakes
1. Buying ETH Because It Is Trending
A rising market does not guarantee continued gains.
2. Using Excessive Leverage
Leverage can magnify losses and increase liquidation risk.
3. Ignoring Gas Fees
Ethereum transactions can have network fees that affect smaller transactions significantly.
4. Trusting Random Token Promotions
Many tokens promoted online carry substantial risk.
5. Connecting Your Wallet to Unknown Websites
A malicious smart contract interaction can potentially put your assets at risk.
6. Sharing Your Seed Phrase
Never share your recovery phrase.
7. Trading Without a Stop Plan
Know when your trade idea is invalid before entering.
8. Revenge Trading
Do not increase position size simply because the previous trade lost money.
Ethereum Security Tips
Ethereum's ecosystem includes thousands of applications, tokens, and smart contracts.
That creates opportunities—but also security risks.
Verify Websites
Use official sources to find the correct website.
Check Contract Addresses
When interacting with tokens or smart contracts, verify the correct contract address from reliable sources.
Avoid Unknown Airdrops
Unexpected tokens or NFTs may be designed to trick users into interacting with malicious contracts or websites.
Use Wallet Permissions Carefully
Review wallet approvals and permissions.
Keep Your Seed Phrase Private
This is one of the most important security rules.
Ethereum vs Ethereum Classic
Beginners sometimes confuse:
Ethereum (ETH)
with
Ethereum Classic (ETC)
They are separate blockchain projects.
Always check the ticker and network carefully before sending assets or trading.
What Is Wrapped ETH?
You may also hear about Wrapped Ether, commonly called WETH.
WETH is a tokenized representation of ETH designed to interact with applications that use token standards such as ERC-20.
ETH and WETH are related, but they are not identical in form.
When using decentralized applications, always understand which asset and network you are interacting with.
Why Ethereum Is Important for Crypto Traders
Ethereum is important because its ecosystem has influenced many areas of cryptocurrency, including:
DeFi
NFTs
Smart contracts
Token creation
Decentralized exchanges
Web3 applications
Understanding Ethereum therefore helps beginners understand much more than just the ETH price chart.
