Key points to remember:
-
A sharp decline in Bitcoin often triggers systemic contagion, causing altcoins to decline via liquidity and trust channels.
-
In times of crisis, the market tends to view crypto as a single risk asset rather than valuing individual utility, as shown by the high BTC-ETH and BTC-XRP correlations.
-
Correlation and beta analyzes are essential to quantify the extent to which Ether and XRP depend on Bitcoin’s performance.
-
Monitoring correlation indicators, using derivatives, and maintaining stable or yield-generating assets can help protect against Bitcoin-related shocks.
The dominance of Bitcoin (BTC) in the cryptocurrency market has long been the defining characteristic of crypto cycles. But what will happen if Bitcoin’s dominance fades or its price drops by 50%? In this scenario, two of the largest coins, Ether (ETH) and XRP (XRP), become critical test cases for how the market reshuffles.
This article explains how to evaluate ETH and XRP during a Bitcoin shock, measure dependence, assess risk, and design effective hedging strategies.
Why Bitcoin Dominance Matters
In traditional equity markets, when the largest player in a sector stumbles, the repercussions are immediate. Small businesses often lose value because they depend on the leader’s ecosystem, investor trust, supply chain links, and reputation. The same logic applies to crypto: Bitcoin serves as an “anchor asset.” When Bitcoin weakens, the entire market loses its sense of stability and direction.
Historically, Bitcoin held a significant share of the crypto market capitalization, known as a measure of “dominance.” Most altcoins, including Ether and XRP, have shown a strong correlation with Bitcoin’s price movements.
For example, following the October 10, 2025 tariff announcement, the crypto market experienced a broad sell-off, with Bitcoin falling sharply. According to CoinMetrics, the BTC-ETH correlation increased from 0.69 to 0.73, while the BTC-XRP correlation increased from 0.75 to 0.77 over the next eight days.
This strong convergence confirms that during a liquidity crisis caused by macroeconomic fears, altcoins do not dissociate based on their individual utility. Metrics such as Ether trading volume or XRP institutional adoption offer little protection in such scenarios.
Instead, high positive correlation serves as an empirical measure of shared systemic risk. This shows that the market views the entire crypto sector as a single asset class. This amplifies the downstream effects of a BTC-driven collapse on ETH and XRP.
The implication is clear: if Bitcoin’s dominance falls or its price collapses, ETH and XRP are unlikely to move independently. They would likely suffer in two ways:
Liquidity/structural channel
The market structure, including derivatives, trading flows, and investor behavior related to BTC, is weakening. A major Bitcoin crash could trigger large-scale liquidations driven by margin calls and cascading sales. This often leads to massive capital outflows that affect all crypto assets, regardless of their fundamentals. They fall simply because they share the same basket of risks.
Feelings channel
A breakdown of the original decentralized asset undermines the fundamental thesis of the entire crypto industry. This erodes investor confidence in the long-term viability of cryptocurrencies. As fear sets in, investors tend to turn to safer assets such as fiat or gold. The result is a prolonged bear market that weakens the investment appetite for Ether and XRP.
How to measure Bitcoin dependence and risk
Step 1: Define the shock scenario
The analysis begins by selecting a plausible, high-impact Bitcoin event. This could involve defining a specific price shock, such as a 50% drop in BTC in 30 days, or a structural change, for example Bitcoin dominance going from 60% to 40%.
Step 2: Quantify dependence
The next step is to calculate the current Pearson correlation coefficient between ETH, XRP and BTC. This statistical measure captures the linear relationship between daily asset returns, providing a baseline for dependence. A value closer to +1 indicates that the altcoin is strongly linked to the performance of BTC.
Step 3: Estimate immediate price reaction
Using the correlation data, apply regression analysis to calculate the beta (β) of each altcoin relative to BTC. The beta coefficient estimates the expected change in the altcoin price for each one-unit change in Bitcoin. This is similar to calculating the beta of a stock relative to a benchmark like the S&P 500 in traditional finance.
For example, if the β of ETH relative to BTC is 1.1 and the defined scenario assumes a 50% decline in BTC, the implied movement of ETH would be -55% (1.1 × -50%).
Step 4: Adjust for liquidity risk and structural risk
The adjustment requires going beyond the simple calculation of beta by taking into account the main structural risks of the market. Restricted FX order books should be analyzed for liquidity risk, while high open interest on derivatives should be assessed for structural risk and possible cascading liquidations.
For example, if the implied -55% move from Step 3 is compounded by low liquidity, the actual realized loss could increase by an additional 10%, resulting in a total decline of -65%. Additionally, review open interest and margin positions, as high leverage can accelerate declines through cascading liquidations.
What happens to Ether and XRP in a Bitcoin shock scenario?
In traditional finance, a sharp selloff in the S&P 500 or the sudden collapse of a major brokerage often triggers a rapid, indiscriminate flight to safety – an effect known as “financial contagion.” The cryptocurrency market exhibits similar dynamics, but in a faster and often more amplified form, usually triggered by a Bitcoin-centric shock.
Data from previous crises, including the collapses of FTX and Terra, reveal a clear pattern: when Bitcoin falls, altcoins are generally dragged down. Bitcoin continues to serve as the market’s leading risk indicator.
In such a scenario, liquidity often rushes to stablecoins or leaves the market altogether in search of protection against volatile assets. Although Ether benefits from a robust Layer 1 utility, it is not immune; in times of market stress, its correlation with Bitcoin often increases, as institutional capital treats both as risk assets. However, Ether’s staking block and its large ecosystem of decentralized applications can provide a utility-focused floor, potentially helping it bounce back faster once the crisis passes.
In contrast, assets such as XRP, which face higher regulatory and structural risks and lack the extensive organic on-chain yield mechanisms of Ether, could be disproportionately impacted. Such shocks often trigger a vicious cycle in which the loss of collective trust outweighs fundamental symbolic utility, leading to a correlated market-wide decline.
Did you know? Although Bitcoin is generally uncorrelated with the S&P 500, during periods of extreme financial stress – such as the COVID-19 pandemic – its correlation with the stock index tends to tighten significantly.
How to hedge your strategy if BTC loses dominance or its price drops
Protecting a crypto portfolio against a sharp decline in Bitcoin requires more than basic diversification. Systemic shocks have shown that extreme correlations often erase the benefits of risk spreading.
Explore derivative products
During periods of extreme panic, the futures market can trade at a large discount to the spot price. This creates opportunities for sophisticated traders to pursue non-directional, relatively low-risk arbitrage. In doing so, they exploit market inefficiencies as a hedge against volatility rather than taking directional price exposure.
Diversify your portfolio with risk buffers
Hold positions in tokenized gold, real-world assets (RWA), or fiat-backed stablecoins to preserve portfolio value. These assets act as liquidity reserves when crypto markets crash.
Monitor dominance and correlation ratios
Monitoring the continued short-term correlation of ETH and XRP with BTC can serve as a real-time warning signal that diversification benefits are disappearing. It confirms when immediate coverage action may be necessary.
Rebalancing towards yield-generating positions
Transfer a portion of your holdings to staking, lending, or liquidity pools that generate yield regardless of market direction. The stable yield can help offset valuation losses and improve recovery potential.
