The Strategy Outline
The cryptocurrency market is undergoing a structural transformation in August 2017, and Ethereum stands at the center of it. As Bitcoin recovers from its hard fork to hit new all-time highs above $3,400, Ethereum has quietly posted a 31.97% weekly gain, trading above $260 with a market capitalization approaching $24.5 billion. But the real story for DeFi-minded investors is what the data reveals about correlation — or the lack of it — between Bitcoin and Ethereum, and what that means for portfolio construction in the decentralized finance space.
The total cryptocurrency market cap has swelled to nearly $118 billion, and for the first time, a credible case can be made that a diversified crypto portfolio outperforms a Bitcoin-only strategy on a risk-adjusted basis. The Cryptocoin Index, a benchmark tracking top digital assets, gained roughly 20% in a single week and reached 3,379 points, validating the diversification thesis that DeFi protocols and decentralized investment vehicles are built upon.
Smart Contract Architecture
Ethereum’s smart contract platform is the backbone of the emerging decentralized finance ecosystem, and its technical fundamentals have never been stronger. The network processes transactions through its Turing-complete virtual machine, enabling complex financial instruments to be coded directly into the blockchain. With over 93.8 million ETH in circulating supply and 24-hour trading volume exceeding $1.48 billion, Ethereum’s liquidity depth rivals that of many traditional financial instruments.
The platform hosts a growing array of decentralized applications — from prediction markets like Augur to decentralized exchange protocols and tokenized asset platforms. Golem, Status, OmiseGO, and Basic Attention Token are all building on Ethereum’s infrastructure, creating network effects that strengthen with each new deployment. The ERC-20 token standard has become the de facto framework for token launches, with dozens of initial coin offerings raising capital on the Ethereum blockchain throughout 2017.
Smart contract security remains an ongoing concern following the DAO hack of 2016, but the ecosystem has matured significantly. Formal verification tools, security audits, and improved development practices are becoming standard. Ethereum Classic, the original chain that persisted after the DAO hard fork, maintains a market cap of $1.4 billion — a testament to the value some participants place on immutability over intervention.
Risk vs. Reward
Research published in August 2017 reveals a fascinating insight: the correlation between Bitcoin and Ethereum returns is remarkably low at just 0.1 over the full sample period, rising modestly to 0.2 in bullish markets. In bearish conditions, the correlation actually turns negative at -0.4, meaning Ethereum tends to generate positive returns when Bitcoin is declining. This negative correlation in downturns creates a natural hedge that portfolio managers in traditional finance spend enormous resources trying to construct.
A risk-adjusted analysis comparing Bitcoin investment, a diversified Cryptocoin Index, and an actively managed index strategy shows that diversification delivers higher average returns with lower overall risk. The weekly Sharpe ratio of the diversified index consistently outperforms Bitcoin alone, even before accounting for transaction costs. For DeFi protocols that automatically rebalance across multiple assets, this data provides the empirical foundation for their investment thesis.
The risk landscape is not without challenges. Regulatory uncertainty, smart contract vulnerabilities, and the nascent state of decentralized governance all pose threats. The total value locked in DeFi protocols remains modest compared to traditional finance, and the user experience for most decentralized applications is still far from consumer-friendly.
Step-by-Step Execution
For investors looking to capitalize on the diversification opportunity, the approach is straightforward. First, establish core positions in both Bitcoin and Ethereum — the two assets that together represent over 80% of the Cryptocoin Index weightings. Bitcoin provides the anchor of market stability and institutional recognition, while Ethereum offers smart contract utility and lower correlation.
Second, allocate a smaller portion to high-conviction altcoins that serve distinct functions. IOTA’s tangle-based architecture for IoT transactions, Neo’s smart economy vision for the Chinese market, and Monero’s privacy-focused blockchain each offer exposure to different technological theses. The data supports this approach: IOTA gained 67% this week, Neo surged 111%, and NEM climbed 52%, demonstrating that diversification across blockchain architectures captures upside that a single-asset strategy misses.
Third, monitor the Bitcoin Cash situation closely. BCH has fallen 35.71% since its creation on August 1, and its declining hash rate relative to Bitcoin suggests the market is consolidating around the original chain. However, BCH’s $3.5 billion market cap means it cannot be ignored entirely, and any reversal could impact the broader altcoin landscape.
Final Thoughts
The week of August 7, 2017 marks an inflection point for crypto portfolio strategy. The data now clearly supports what DeFi proponents have been arguing: a diversified approach to cryptocurrency investment delivers superior risk-adjusted returns compared to a Bitcoin-only strategy. With ETH/BTC correlation near zero in bullish markets and negative in bearish ones, the mathematical case for holding both assets — and extending into carefully selected altcoins — has never been stronger.
The coming months will test this thesis. The November SegWit2x activation could create new volatility, Ethereum’s Metropolis upgrade promises significant protocol improvements, and the ICO market continues to expand the Ethereum ecosystem at a breakneck pace. For DeFi builders and investors alike, the opportunity is to construct portfolios and protocols that capture the diversification premium the data now reveals.

31.97% weekly gain on ETH while everyone was obsessing over the Bitcoin fork. classic misdirection by the market
eth was doing its own thing the whole time while every headline screamed bitcoin fork this, bitcoin fork that. classic recency bias from the media
btc fork was the loudest narrative of 2017 and eth still quietly outperformed. tells you everything about where media attention vs actual returns diverge
The correlation data is what matters here. BTC and ETH moving independently is exactly what portfolio theory predicts as the space matures.
^ agreed. been saying this since the eth/btc ratio started moving on its own. diversification actually works when assets decouple
the correlation breakdown between btc and eth was the most underrated signal of that cycle. most portfolios were just 100% btc and missed the diversification alpha entirely
Cryptocoin Index at 3,379 points with a 20% weekly jump. wonder how many people actually tracked that benchmark back then
almost nobody tracked it. most people in 2017 could barely tell you the top 10 coins by market cap let alone a benchmark index. we were all just guessing
