1. Investment Thesis: Fundamentals Over Hype
In 2019, the crypto market was transitioning from the initial coin offering (ICO) frenzy of 2017–2018 to a more mature, utility-driven landscape. A robust investment thesis focused on problem-solution fit, network effects, and developer activity rather than speculative narratives.
🔍 Core questions to ask
- Does the protocol solve a real, durable problem?
- Is there a clear use case that cannot be easily replicated?
- Who are the competitors, and what is the moat?
- Is the team credible and transparent?
📈 2019 market context
- Bitcoin dominance rose from ~50% to over 70% during 2019.
- Ethereum transitioned toward Proof-of-Stake preparations.
- Binance Coin (BNB) gained traction due to exchange utility.
- Privacy coins (Monero, Zcash) faced regulatory scrutiny.
2. Time Horizon: Matching Strategy to Goals
Your time horizon is the single most important factor in determining which crypto assets are suitable. In 2019, the market exhibited clear cyclical behaviour, with the halving narrative (Bitcoin halving in May 2020) driving long-term expectations.
Short-Term (≤1 year)
Traders focused on momentum, news events, and technical analysis. In 2019, short-term opportunities arose from regulatory announcements, exchange listings, and protocol upgrades. However, trading carries significant risk—timing the market is notoriously difficult.
Medium-Term (1–3 years)
Investors with a 1- to 3-year horizon looked at adoption curves, network growth, and upcoming milestones. The Bitcoin halving in May 2020 was a key event that many believed would drive price appreciation, though historical patterns are not guarantees.
Long-Term (3+ years)
Long-term holders (often called "HODLers") in 2019 prioritised assets with the strongest network effects and institutional adoption potential. Bitcoin and Ethereum were the primary candidates, with some allocating to projects like Chainlink (LINK) or Tezos (XTZ) for longer-term technological bets.
3. Diversification Across Crypto Sectors
Diversification is a cornerstone of risk management. In 2019, crypto could be broadly categorised into several sectors, each with distinct risk-return profiles.
| Sector | Primary Role | 2019 Representative | Risk Profile |
|---|---|---|---|
| Store of Value | Digital gold, inflation hedge | Bitcoin (BTC) | Lower volatility, high liquidity |
| Smart Contract Platforms | Decentralised applications (dApps) | Ethereum (ETH), EOS | Medium volatility, ecosystem risk |
| Exchange Tokens | Fee discounts, utility | Binance Coin (BNB) | Correlated with exchange performance |
| Privacy & Anonymity | Confidential transactions | Monero (XMR), Zcash (ZEC) | Regulatory risk, niche adoption |
| Oracles & Infrastructure | Connecting blockchains to external data | Chainlink (LINK) | High growth potential, speculative |
A balanced 2019 portfolio might have allocated 60–70% to core assets (BTC, ETH) and the remainder to high-conviction altcoins with clear utility. Over-diversification into dozens of small-cap coins often increases correlation and reduces alpha.
4. Valuation Frameworks for Crypto Assets
Traditional valuation metrics (P/E ratios, discounted cash flows) often fail for crypto assets. In 2019, investors relied on on-chain and network-based metrics.
Network Value to Transactions (NVT)
NVT ratio compares network value (market cap) to transaction volume. A high NVT may indicate overvaluation relative to economic activity on the network. In 2019, Bitcoin's NVT fluctuated widely, and analysts used it to gauge speculative froth.
Market Value to Realised Value (MVRV)
MVRV compares market cap to realised cap (the total acquisition cost of all coins). An MVRV above 3–4 often signals an overextended market, while values below 1 indicate undervaluation relative to historical cost basis.
Stock-to-Flow (S2F) Model
The S2F model, popularised in 2019, relates the existing stock of an asset to its annual flow of new production. For Bitcoin, the 2020 halving was projected to increase S2F, implying a higher price. Caution: This model has been heavily criticised and is not a reliable predictor. Always treat such models as one input among many.
5. Rebalancing to Control Risk
Rebalancing involves periodically adjusting your portfolio back to target weights. In the volatile 2019 market, rebalancing helped lock in gains from outperforming assets and buy into laggards at lower prices.
- Time-based rebalancing: e.g., quarterly or semi-annually. This removes emotion and enforces discipline.
- Threshold-based rebalancing: e.g., when an asset deviates by more than 20% from its target weight, rebalance back.
For a 60/40 BTC/ETH portfolio in 2019, if BTC outperformed and became 70%, you would sell some BTC and buy ETH to restore the 60/40 split. Rebalancing incurs transaction costs and potential CGT events (where applicable).
6. Downside Risk and Scenario Planning
Crypto markets are notoriously volatile. In 2019, the market experienced several sharp corrections, including a drop from ~$14,000 in June to ~$6,600 in December. Effective downside management is essential.
Black Swan Scenarios
- Regulatory crackdowns: In 2019, the US SEC, China's central bank, and other regulators issued guidance that affected market sentiment.
- Technical failures: Network hacks, consensus failures, or critical vulnerabilities.
- Macroeconomic shocks: Global interest rates, trade wars, or liquidity crunches.
🛡️ Stress-testing your portfolio
- Simulate a 50% drawdown – how would your portfolio respond?
- What is your maximum tolerable loss before you panic?
- Set stop-losses or use options/futures (only if you understand the products).
- Maintain a cash buffer to deploy during extreme dips.
7. Common Mistakes
- ❌ Chasing past performance: In 2019, many investors bought coins that had already surged 10x, only to see them correct. Past returns are not indicative of future results.
- ❌ Neglecting liquidity: Investing in low-market-cap altcoins that are difficult to sell without moving the price.
- ❌ Over-reliance on social media hype: Telegram groups, Twitter influencers, and YouTube "gurus" often promote coins for personal gain.
- ❌ Ignoring tax implications: Disposals, trades, and swaps can trigger taxable events. In many jurisdictions, crypto-to-crypto trades are taxable.
- ❌ Not securing private keys: Leaving assets on exchanges exposes you to hack or insolvency risk. In 2019, several exchanges were compromised.
- ❌ Letting emotions drive decisions: Fear of missing out (FOMO) and panic selling are the two biggest destroyers of returns.
8. Practical Scenario: Building a 2019 Portfolio
📘 Scenario: Alex's $10,000 Investment Plan
In January 2019, Alex has $10,000 to invest in crypto. Using the framework, Alex sets:
- Time horizon: 3 years (until 2022).
- Risk tolerance: Moderate – can accept a 40% drawdown.
- Target allocation:
- 50% Bitcoin (BTC) – core store of value.
- 25% Ethereum (ETH) – smart contract platform.
- 15% Binance Coin (BNB) – exchange utility and growth.
- 10% Chainlink (LINK) – high-conviction infrastructure play.
Rebalancing: Alex rebalances quarterly.
Downside scenario: Alex stress-tests a 50% market crash.
The portfolio drops to ~$6,500, but Alex holds and continues to rebalance, buying more BTC and ETH during the dip.
Outcome (retrospective): By December 2021, the portfolio would have significantly appreciated, though past results do not guarantee future outcomes. The key lesson is that the process of disciplined allocation, rebalancing, and risk management provided structure in a chaotic market.

9. Risk Warning
⚠️ Key Risks in Crypto Investing
- Extreme volatility: Crypto prices can fluctuate by 20–50% in a single day. You must be prepared for total loss of capital.
- Regulatory uncertainty: Laws vary by jurisdiction and can change rapidly. In 2019, global regulators were still formulating frameworks.
- Technology risks: Smart contract bugs, 51% attacks, and consensus failures can render a project worthless.
- Exchange and custody risks: Hacks, exit scams, and insolvency of exchanges are real threats. Use hardware wallets and insured custodians where possible.
- Liquidity risk: Some altcoins have thin order books, making it difficult to exit positions without substantial slippage.
- Tax complexity: In many countries, every crypto disposal is a taxable event. Failure to report can result in penalties.

10. Frequently Asked Questions
Was Bitcoin the best cryptocurrency to invest in during 2019?
Bitcoin was the best-performing major asset in 2019, gaining over 90% by year-end. However, altcoins like BNB and Chainlink outperformed BTC in percentage terms. The "best" asset depends on your risk tolerance and time horizon. Bitcoin offered relatively lower volatility and higher liquidity, making it a core holding for many.
How did the 2019 crypto market differ from today?
In 2019, the market was smaller, with total crypto market cap around $150–$300 billion (compared to over $2 trillion today). DeFi was nascent, NFTs were not yet mainstream, and institutional products (like futures and ETFs) were limited. Regulatory clarity was also much lower.
What valuation metric was most reliable in 2019?
No single metric was perfectly reliable. On-chain metrics like MVRV and NVT provided insight into market psychology, while the Stock-to-Flow model gained popularity. However, all models have limitations, and many investors combined multiple indicators with fundamental research.
Should I have invested in initial coin offerings (ICOs) in 2019?
By 2019, the ICO boom had largely faded, and many previous ICOs were trading below their offering prices. While some legitimate projects conducted security token offerings (STOs) or simple agreements for future tokens (SAFTs), the ICO model carried high fraud risk and regulatory scrutiny. Most prudent investors avoided ICOs in 2019.
How did the Bitcoin halving affect 2019 investment decisions?
The Bitcoin halving (scheduled for May 2020) was a major narrative in 2019. Many investors accumulated BTC in anticipation of supply-side scarcity. Historical data showed that prior halvings (2012, 2016) preceded significant bull runs, but historical patterns are not guarantees. The halving narrative influenced both short-term trading and long-term holding strategies.
Is diversification across crypto sectors effective?
Yes, diversification can reduce idiosyncratic risk. In 2019, a portfolio with a mix of store-of-value (BTC), smart contract (ETH), and utility tokens (BNB, LINK) would have captured multiple growth drivers. However, over-diversification (e.g., holding 50+ coins) often dilutes returns and increases complexity without adding meaningful protection.
What was the biggest risk in 2019 that investors ignored?
Regulatory intervention was a persistent, underappreciated risk. The SEC's enforcement actions against Kik and other projects, as well as China's crackdown on crypto exchanges, caused sharp but temporary sell-offs. Many investors underestimated how quickly regulatory news could impact prices.
How can I apply a 2019-style framework to today's market?
The framework—thesis, time horizon, diversification, valuation, rebalancing, and downside planning—remains timeless. However, you must update your data: research current market caps, new protocols, regulatory changes, and macroeconomic conditions. Always verify current prices, fees, and platform availability before making any decisions.
