What Is Cryptocurrency?
- A digital asset secured by cryptography and recorded on a decentralized blockchain
- Transactions are verified through consensus mechanisms without a central intermediary
- Thousands of cryptocurrencies exist, but market cap is heavily concentrated in a few
- Bitcoin is a peer-to-peer store of value; Ethereum enables smart contracts and applications
Portfolio Role and Allocation Sizing
- Crypto has shown low long-term correlation with stocks and bonds in some periods
- Extreme volatility means even small allocations can meaningfully affect portfolio risk
- Many advisors who include crypto suggest limiting it to 1 to 5% of a diversified portfolio
- Position sizing should reflect willingness to accept potentially total loss
Volatility and Risk Profile
- Bitcoin has experienced drawdowns exceeding 70% multiple times in its history
- Daily price swings of 5 to 10% are not uncommon, far exceeding most traditional assets
- Volatility has modestly declined over time as market cap and adoption have grown
- Investors should be prepared for extended bear markets lasting a year or longer
Custody Options
- Centralized exchanges offer convenience but expose assets to counterparty and hack risk
- Hardware wallets store private keys offline, giving the owner full control
- Institutional custodians provide insured storage required by many regulated funds
- Lost private keys mean permanently lost assets, self-custody requires careful management
Regulatory Landscape
- The IRS treats cryptocurrency as property, making every sale or exchange taxable
- SEC, CFTC, and state regulators have overlapping and evolving jurisdictional claims
- Spot Bitcoin ETFs were approved in the US in 2024, broadening regulated access
- Regulatory frameworks differ significantly across countries and continue to change
Common Investment Approaches
- Buy-and-hold treats crypto as a long-term position, avoiding frequent taxable events
- Dollar-cost averaging spreads purchases over time to reduce volatility impact
- ETFs and publicly traded funds provide exposure without direct custody responsibilities
- Active trading carries high transaction costs, tax complexity, and timing risk
Key Risks and Tax Considerations
- Exchange hacks and platform insolvencies have caused billions in investor losses
- Regulatory bans or restrictive legislation could significantly reduce asset values
- Crypto-to-crypto swaps, staking rewards, and airdrops are all taxable events
- Detailed transaction records are critical because exchanges may not provide complete 1099s
