The literature relevant to this study bifurcates Proof of stake into two distinct yet interconnected domains. The first is the foundational body of work on volatility modeling in finance, which has been a key topic in financial econometrics. The use of high-frequency data substantiates the discoveries regarding volatility modeling, among which the impact of signed returns on future volatility, referred to as the leverage effect, represents a well-established empirical regularity in financial market data. Bollerslev et al. (2006); Barndorff-Nielsen et al. (2008); Chen and Ghysels (2011) highlights the effect of negative equity returns on increasing future volatility.

In essence, volatility is a prominent feature of the cryptocurrency market that cannot be ignored. Further understanding volatility can allow traders to develop effective strategies to navigate market swings. In the crypto space, users call this ‘buying the dip’ and ‘taking profit’ — in other words, as volatility accompanies the crypto market, one can wait for a price dip to buy and https://www.xcritical.com/ often sell on a high soon after.

The selected stocks come from the NASDAQ technology index (NDXT), whose returns are positively correlated with the crypto volatility trading return of cryptocurrencies in the past years (Goodell and Goutte 2021). We provide an in-depth analysis of price volatility in the cryptocurrency ecosystem at both the aggregate and the individual levels. At the aggregate level, we analyzed the effects of signed volatility, daily leverage effect, and signed jumps on the ecosystem as a whole. In addition, we compared the results obtained on the cryptocurrencies cross-section to a cross-section of stocks, a more mature asset class.
- Mensi et al. (2021) focuses on the portfolio management implication of high-frequency volatility patterns.
- Alternatively, price may go down when the economy or market is not performing well or is not expected to perform well, and investors are generally not as willing to invest in riskier assets.
- They have designed and submitted a tokenized cash-back patent, where customers can get cash back within the social good cashback platform when they shop at major online retailers, as an example.
- This behavior underscores a herding effect in investment decisions, influenced by a collective eagerness to participate in perceived lucrative opportunities without fully grasping the market’s complexities.
- The entities in the cryptocurrency cross-section have around four times the available observation compared to equities.
- Specifically, Jha and Baur (2020); Ftiti et al. (2021) explores the analysis of cryptocurrency volatility by using intraday data of a small number of coins and tokens.
Strategies for Trading Crypto During Volatile Phases
While central banks do not control cryptocurrencies, some crypto analysts have observed that the US central bank in particular may be indirectly influencing the price of crypto. Crypto is a high-risk investment compared with most traditional investments (e.g., stocks and bonds). Like other riskier investments, the price of crypto may have a tendency to perform better when the economy and/or market is generally thought of as doing well or expected to do well, and investors are willing to take more risk. Alternatively, price may go down when the economy or market is not performing well or is not expected to perform well, and investors are generally not as willing to invest in riskier assets. Technical analysis is also a popular approach used by traders to predict and manage volatility in the cryptocurrency market.
The estimation procedure remains the same as described, even when we restrict the time window of observation used for the estimation and when we estimate the model specifications individually over each entity of a specific cross-section instead of as a panel. For both the cross-sections, the RV estimator is highly correlated to its signed components and the continuous volatility estimator BV, as expected by construction. On the contrary, the SJV estimators and their signed components are not strongly correlated with the other estimators for the equity cross-section. At the same time, such a correlation tends to be higher in the case of cryptocurrencies.
Bitcoin’s Lightning Network is designed to facilitate faster transactions at a larger scale. Stablecoins, pegged in value to fiat currencies like the dollar or other assets, eliminate high day-to-day volatility by design. They can be used to keep money in the crypto ecosystem—protected from short-term fluctuations and, in theory, easier and faster than traditional fiat currencies–to exchange with Bitcoin or Ethereum. However, their relative novelty opens the door for long-tail risk as well as fraud.
When crypto traders diversify their portfolios, they buy multiple digital assets with different risk profiles rather than concentrating all their funds into one cryptocurrency. For example, some traders buy Bitcoin to take advantage of its relative stability versus more speculative altcoins. Mixing established cryptocurrencies with higher-risk projects in different segments of the crypto industry helps traders mitigate the overall price volatility of their holdings. Volatility in the crypto market measures the average changes in the value of digital assets like Bitcoin and Ethereum. When financial analysts say a cryptocurrency is “more volatile” than other assets, they mean it tends to experience wider and more frequent price swings than “less volatile” coins or tokens.
When you estimate the model for the entire panel, the OLS method captures the average effect across all units. However, when you analyze individual time series, the specific characteristics of each unit come into play. If a particular time series has unique features that are not well-captured by the OLS assumptions (like non-linearity, or structural breaks), the estimation might fail to converge. However, this difference does not impact how we construct n-days volatility estimators that follow the same process for both asset classes. It is also flexible because it can be generalized to other volatility measures that reflect specific aspects of the volatility process, such as the realized semivariance to assess the downside risk of an asset (see Aït-Sahalia and Jacod (2014) for more details). It is possible to calculate the jump parts of the volatility estimators from Eq.
Identifying the volatility dynamics and comparing it to a more renowned asset class is a crucial aspect to consider for the cryptocurrency ecosystem as a whole. A better assessment of the cryptocurrency market’s volatility could stabilize the market by producing a more liquid and reliable derivative market, which nowadays accounts for a few large centralized exchanges such as Binance and various residual exchanges. Specifically, Jha and Baur (2020); Ftiti et al. (2021) explores the analysis of cryptocurrency volatility by using intraday data of a small number of coins and tokens.
We compute the realized variance estimator described in Section 3.1 using the 5-minute level data in Section 3.2 for each of the cryptocurrencies. Once we estimate these volatility proxies, it is straightforward to derive the regressor of the reference model in Eq. Equation 8 by lagging or averaging over the information according to the specification. The HAR model’s main benefit is that it allows for incorporating multiple time scales, which is particularly important because volatility exhibits specific patterns at different frequencies.
The Newey-West HAC estimators allow us to produce standard errors that are robust to these issues, thereby ensuring that our inference is more reliable. Cryptocurrencies have continuously gained popularity since Bitcoin (BTC), the first and most well-known cryptocurrency, was created in 2009, right after the 2008 financial crisis, as a response to traditional financial institutions’ perceived lack of trust. One reason behind this sharp increase in interest is their potential for enhancing financial freedom and removing intermediaries from financial transactions. Individuals can make peer-to-peer transactions with cryptocurrencies without a central authority or intermediaries. This characteristic has made them particularly appealing to those concerned about government control and censorship in traditional financial systems.
The econometrics literature has shown how high-frequency price data can improve the estimation and predictability of the volatility for a cross-section of equities (Patton and Sheppard 2015; Bollerslev et al. 2020). Volatility refers to rapid and significant price fluctuations that occur frequently in the cryptocurrency market. Unlike traditional financial (TradFi) markets, where price movements of currencies are usually less pronounced, cryptocurrencies can experience wild swings in a matter of hours or even minutes. This volatility can be attributed to several factors, including the emergent nature of the industry, market sentiment, regulatory developments, technological advancements, and macroeconomic events.
Day-to-day price fluctuations of cryptocurrencies eclipse those of traditional currencies, stocks, and precious metals, and do so consistently across assets and time periods. This phenomenon is not entirely driven by the longer-term ups and downs reported in headlines. Bitcoin, Ethereum, and other cryptocurrencies frequently exhibit daily price drops during bull markets and increases during bear markets far in excess of traditional assets. The interactive chart below provides one way to visualize this day-to-day volatility—the daily percentage increase or decrease in price in U.S. dollars from the previous day. 9 are instrumental in describing past signed returns’ impact on future volatility.
Before doing any trading, you need to ensure you are comfortable with volatile trading. Defining concrete goals and setting measures to decrease risk are necessary to keep your securities safe. However, they’re also needed to keep you, the trader, impartial in your judgment. Sure, volatility is highly risky but with the right knowledge, you can use volatile trading to your advantage. Volatility is spurred before and during this time and becomes worse just after the quarterly results.
For some cryptocurrencies, the individual estimation of the HAR-like model does not converge; hence, these cryptocurrencies are excluded from the graphic representation. For each model specification described in this section, we estimate a panel regression to capture the average contribution of each entity in a specific asset class and explain the volatility dynamics for the considered group. Therefore, the panel regression is carried out separately for cryptocurrencies and equities for a thoughtful comparison. Each panel HAR is estimated through a weighted least squares (WLS) method to account for frequent regime shifting retrieved in the dynamics of our time series.
