Understanding Cryptocurrency Basics

Cryptocurrency is digital currency secured by cryptography, operating on decentralized networks called blockchain. Unlike traditional currency controlled by governments, cryptocurrencies are decentralized and transparent.

What Makes Crypto Different

Traditional Currency:

• Controlled by central banks
• Government-backed
• Centralized ledger
• Subject to inflation
• Can be printed without limit

Cryptocurrency:

• Decentralized network
• Cryptographically secured
• Transparent transactions
• Fixed supply (many coins)
• No central authority

How Blockchain Works

Blockchain is a distributed ledger recording all transactions:

1. Transaction Initiated: User sends digital asset
2. Broadcasting: Network nodes receive transaction
3. Verification: Nodes validate transaction using cryptographic algorithms
4. Block Creation: Valid transactions bundled into block
5. Consensus: Network reaches consensus (Proof of Work, Proof of Stake)
6. Chain Addition: Block added to chain permanently
7. Immutable Record: Cryptographically linked to previous blocks

This system makes blockchain:

• Transparent: All transactions visible
• Immutable: Cannot alter past transactions
• Secure: Cryptographic protection
• Decentralized: No single point of failure

Cryptocurrency Investment Strategies

Strategy 1: Dollar-Cost Averaging (DCA)

Investing fixed amount regularly reduces timing risk.

Example DCA Strategy:

• Invest $500 monthly
• No matter price fluctuation
• Reduces impact of volatility
• Average cost per coin decreases with dips

DCA Benefits:

• Removes emotion from investing
• Works regardless of market conditions
• Suitable for volatile assets
• Builds wealth systematically

Historical Example: Investing $500/month in Bitcoin:

• 2017 bull market through 2022 bear: Still profitable
• Weathered 70%+ price decline
• Recovered with 2023-2024 rally
• Long-term winner despite volatility

Strategy 2: Core and Satellite Approach

Core (80% of crypto allocation):

• Bitcoin and Ethereum only
• Largest, most established
• Proven longevity
• Institutional adoption

Satellite (20% of crypto allocation):

• Alternative projects with potential
• Higher risk, higher reward
• Emerging blockchain solutions
• DeFi or Web3 projects

Allocation Example: $10,000 total crypto allocation:

• Bitcoin: $5,000 (50%)
• Ethereum: $3,000 (30%)
• Altcoins: $2,000 (20%)

Strategy 3: Fundamental Analysis

Evaluating long-term viability of projects.

Key Questions:

1. Problem & Solution:

   • What problem does this solve?
   • Advantage over alternatives?
   • Real demand for solution?

2. Team Quality:

   • Experienced developers?
   • Track record in industry?
   • Sufficient funding?

3. Technology:

   • Sound architecture?
   • Security audits passed?
   • Scalability solutions?

4. Adoption:

   • Growing user base?
   • Developer engagement?
   • Enterprise partnerships?

5. Tokenomics:

   • Reasonable supply structure?
   • Lock-up schedules for early investors?
   • Inflation sustainable?

6. Competition:

   • Unique advantage?
   • Competitive barriers?
   • Survivability in crowded space?

Strategy 4: Technical Analysis

Analyzing price patterns for timing.

Common Indicators:

Support & Resistance:

• Support: Price level where buying increases (floor)
• Resistance: Price level where selling increases (ceiling)
• Break above resistance = bullish
• Break below support = bearish

Moving Averages:

• Average price over period (50, 100, 200-day)
• Price above moving average = uptrend
• Price below moving average = downtrend

RSI (Relative Strength Index):

• Measures momentum (0-100 scale)

• 70 = overbought (potential pullback)

• < 30 = oversold (potential bounce)
• 40-60 = neutral

MACD (Moving Average Convergence Divergence):

• Momentum and trend indicator
• Bullish when MACD > signal line
• Bearish when MACD < signal line

Note: Crypto is volatile; technical analysis is tool, not guarantee.

Tax Implications of Crypto

Taxable Events

Capital Gains:

• Selling cryptocurrency at profit = capital gains tax
• Long-term (>1 year): Favorable rates (15-20%)
• Short-term (<1 year): Ordinary income rates (up to 37%)

Trading:

• Exchanging one coin for another = taxable event
• Even if profit not realized
• Requires tracking each transaction

Mining/Staking:

• Rewards counted as income
• Taxed as ordinary income in year received
• Later sale may incur capital gains

Airdrops/Forks:

• Free coins = income
• Taxed at fair market value at receipt
• Later sale = capital gains/loss

Tax-Efficient Strategies

Long-Term Holding:

• Hold Bitcoin/Ethereum > 1 year
• Capital gains rate (15-20%) vs ordinary income (37%)
• Significant tax savings

Tax-Loss Harvesting:

• Sell losing positions
• Use loss to offset gains
• Can deduct up to $3,000/year in losses
• Reinvest in similar (different) coins

Donation Strategy:

• Donate appreciated coin to charity
• Avoid capital gains tax entirely
• Take charitable deduction
• Maximize impact of giving

Records & Documentation:

• Keep detailed transaction records
• Use crypto tax software (CoinTracker, Koinly)
• Track cost basis and dates
• Prepare for audit

Tax Software Options
