Pesatnya perkembangan teknologi blockchain dan arus globalisasi telah mendorong penggunaan Bitcoin di Indonesia, yang kini diakui sebagai komoditas dalam perdagangan berjangka. Namun, karakteristik anonimitas dan desentralisasi mata uang digital ini membuka celah signifikan bagi kemunculan cybercrime, seperti pencucian uang dan peretasan, yang menuntut perhatian yuridis serius. Penelitian ini bertujuan menganalisis dampak teknologi tersebut terhadap risiko kejahatan siber serta efektivitas regulasi yang berlaku. Metode yang digunakan adalah yuridis normatif dengan pendekatan perundang-undangan untuk menelaah kerangka hukum terkait. Hasil penelitian menunjukkan adanya dualisme regulasi di Indonesia, di mana Bappebti melegalkan Bitcoin sebagai aset investasi, sementara Bank Indonesia melarangnya sebagai alat pembayaran. Ketidaksinkronan ini, diperparah dengan sifat lintas batas blockchain, menciptakan tantangan dalam penegakan hukum terhadap kejahatan siber. Disimpulkan bahwa harmonisasi regulasi antara otoritas keuangan dan penguatan aturan keamanan siber sangat mendesak dilakukan guna memitigasi risiko kejahatan tanpa menghambat inovasi ekonomi digital.

Cryptocurrency has become a rapidly developing digital asset class that attracts widespread investor interest due to its decentralized, anonymous, and highly volatile nature. Such volatility creates uncertainty in market movements, making it important to understand the factors that drive fluctuations in returns. This research aims to examine how fundamental indicators namely price, trading volume, and market capitalization affect return volatility, as well as to determine which cryptocurrency demonstrates the highest market efficiency based on risk assessment. The study uses panel data covering the five largest cryptocurrencies by market capitalization (Bitcoin, Ethereum, Tether, USD Coin, and Binance Coin) over the period 2019–2023. The analytical methods applied include panel data regression to identify the determinants of volatility and Value at Risk (VaR) to measure asset risk and efficiency. The findings show that price and trading volume positively and significantly increase return volatility, whereas market capitalization exerts a negative and significant effect, indicating its stabilizing role. Based on VaR analysis, Binance Coin (BNB) emerges as the asset with the highest market efficiency. The study concludes that fundamental indicators play a crucial role in shaping volatility and that BNB offers relatively better risk performance compared to its peers.

The rapid growth of digital financial technology has introduced new economic instruments that require re-evaluation through the lens of Islamic economic law, one of which is Bitcoin. This study aims to analyze the legal standing of Bitcoin as a means of transaction and investment using a normative legal approach. Data were obtained through extensive literature review involving primary and secondary sources, including Islamic jurisprudence, maqāṣid al-sharī‘ah, qawā‘id fiqhiyyah, official fatwas, and contemporary technological and economic studies. The analysis employed normative and reconstructive methods to assess the compatibility of Bitcoin’s characteristics with the principles of Islamic law. The findings indicate that Bitcoin may be classified as a form of digital māl because it possesses utility, can be lawfully owned, and is tradable within open market mechanisms. However, its extreme price volatility, limited public acceptance, and absence of state-backed legitimacy make it unsuitable as a lawful medium of exchange in Islamic transactions. Conversely, Bitcoin may be permitted as an investment instrument under strict conditions, provided the activity avoids speculative motives, ensures transparency, and follows prudent financial conduct. Based on these assessments, this study concludes that Bitcoin is more appropriately categorized as a digital commodity rather than a transactional currency. This research contributes conceptually to the development of sharia-compliant crypto-asset regulations and opens avenues for further exploration on designing more stable and ethically aligned digital financial instruments.

Over the past 20 years, developments in digital technology have led to the emergence of financial innovation in the form of cryptocurrencies, with Bitcoin being the main pioneer. Bitcoin is a decentralized, blockchain-based electronic payment system that is not controlled by a single financial institution. Although its presence facilitates quick and straightforward cross-border transactions, it also raises ethical and legal issues, especially when taking into account Islamic law, which strongly emphasizes justice, certainty, and the welfare of society. This paper aims to investigate the usage of Bitcoin in modern economic transactions from the standpoint of Islamic and international law. This study investigates Islamic legal sources, the views of Islamic scholars, fatwas (religious decrees), and international laws and regulations pertaining to cryptocurrency assets using a qualitative, normative-empirical methodology. The results show that, although opinions among scholars differ, the usage of Bitcoin is subject to ijtihadiyah (Islamic ijtihad) in Islamic law. Some reject it because of its great volatility and speculative potential, while others allow it as long as it provides advantages and does not include riba, gharar, or maysir (the risks associated with gambling). In terms of international law, Bitcoin is typically seen as a digital asset that has to be closely watched in order to preserve economic stability and deter financial crime. Therefore, balanced legislation is required to guarantee that the usage of Bitcoin is in line with the principles of sharia maqasid and global economic fairness.

This study examines the comparative volatility of gold and Bitcoin over the period January 2020 to August 2025, using monthly data and employing descriptive statistics, the Augmented Dickey-Fuller (ADF) test, GARCH (1,1), and the Dynamic Conditional Correlation Generalized Autoregressive Conditional Heteroskedasticity (DCC-GARCH) model estimated with EViews 13. The results show that Bitcoin is characterized by extreme and persistent volatility, reflecting its speculative nature, whereas gold remains stable and functions as a conventional safe-haven asset. Correlation analysis indicates that the relationship between gold and Bitcoin is generally weak but dynamic, as the strength and direction of their co-movements change across different market conditions. These findings highlight the potential role of gold as a hedge and Bitcoin as a speculative diversifier, offering insights for portfolio diversification and risk management. These results also suggest that investors should carefully consider their risk tolerance and investment horizon when allocating assets between traditional and digital commodities.

This study analyzes the effect of Bitcoin prices, the LQ45 Index, mutual fund net asset value (NAV), and the net profit margin (NPM) of gold mining companies on the price of gold as a safe haven asset within the context of the Indonesian financial market. Gold is often seen as a safe haven asset that is the primary choice of investors when economic uncertainty increases, but the relationship between gold and various other investment instruments still requires further study. This study uses a multiple linear regression method with a robust standard errors approach to analyze 420 monthly and quarterly data observations during the 2018-2022 period. The results of the study found that the price of Bitcoin and the NPM of gold mining companies had a significant positive influence on the price of gold, while the LQ45 Index had a significant influence effect. Meanwhile, the NAV of mutual funds showed a significant positive influence that was not in line with the initial hypothesis. These findings indicate that gold does not always function absolutely as a safe haven asset, as its role is contextual and still influenced by the dynamics of other investment instruments such as digital assets, stock markets, and mutual funds. The study's results make an important contribution to financial literature by proving that the safe haven characteristics of gold are complex and dynamic, so investors need to consider various factors and market conditions before allocating investments to gold as a hedging strategy in their portfolios.

This study aims to analyze cryptocurrency investments and the risks faced by beginner investors who own digital assets such as Bitcoin, Solana, XRP, and other coins that have been increasing in value over the past few years, especially among the general public and retail investors. Not only retail investors, but governments also now hold digital assets, as has already happened. However, the unstable price and lack of global legal oversight make investing in cryptocurrency highly risky, especially for those with less knowledge and experience. The methods used in this study include literature review, descriptive analysis of historical price data for cryptocurrency, case studies, and interviews with several beginner investors. The findings show that cryptocurrency can generate large profits in a short time, but the risk of losing capital is also very high. Therefore, having a good understanding of blockchain technology, risk management, and investment psychology before starting to invest is important. This study is hoped to serve as a reference for beginner investors when considering decisions to invest in cryptocurrency.

This study aims to analyze the impact of the Russian invasion of Ukraine on February 24, 2022, on the Indonesian capital market, particularly on the stocks listed in the LQ45 index, as well as on exchange rates and cryptocurrency trading volumes. The research employs a quantitative approach using an event study method, focusing on a 15-day observation window—comprising 7 days before, the day of, and 7 days after the invasion event. The variables analyzed include abnormal return (AR), trading volume activity (TVA), exchange rates, and cryptocurrency transaction volume. The research sample consists of issuers listed in the LQ45 index and the three largest cryptocurrencies by market capitalization—Bitcoin, Ethereum, and Tether (USDT)—selected through purposive sampling. The findings indicate that the Russian invasion of Ukraine had a significant impact on abnormal returns and trading volume activity of LQ45 stocks, as well as on exchange rates and cryptocurrency trading volumes. This geopolitical event emerged as an external factor contributing to market uncertainty, prompting investors to adjust their investment strategies in both stock markets and digital assets. These findings confirm that global conflicts are closely linked to the dynamics of domestic financial markets.

Bitcoin is one of the most prominent digital assets in the modern financial era due to its high volatility and huge profit potential. However, its extreme price volatility also makes it a high-risk asset, so a reliable forecasting approach is needed to help investors make more rational decisions. This study aims to forecast Bitcoin price using the Moving Average (MA) method, specifically MA3, by utilizing monthly historical data of Bitcoin price in USD currency obtained from investing.com website. The MA3 method was chosen for its ability to smooth out short-term fluctuations and identify the direction of price trends. The forecasting process is performed by calculating the average of the last three months' prices for each point in time and compared to the actual price to evaluate its accuracy. The evaluation is done using various prediction error metrics, namely Error, Absolute Error, Squared Error, and Percentage Error. The results of the analysis show that the MA method provides a fairly representative picture of price trends and can be used as an early indicator in short-term investment strategies. Thus, the Moving Average method proves to be a simple but effective prediction tool, especially for novice investors in the dynamic crypto asset market.

Bitcoin sebagai salah satu cryptocurrency paling populer yang menawarkan peluang investasi besar namun disertai dengan volatilitas harga yang tinggi. Penelitian ini bertujuan untuk memprediksi harga Bitcoin menggunakan model Support Vector Machine (SVM) dan menganalisis risiko pasar yang melekat. Dataset historis Bitcoin digunakan untuk melatih model dengan fitur seperti harga pembukaan, harga tertinggi, harga terendah, dan volume perdagangan. Penelitian menggunakan model SVM yang dioptimalkan melalui tuning parameter untuk meningkatkan akurasi prediksi. Evaluasi model dilakukan menggunakan metrik Mean Absolute Error (MAE) dan Root Mean Squared Error (RMSE). Hasil evaluasi menunjukkan performa model yang baik dengan MAE sebesar 0,0036 dan RMSE sebesar 0,0050. Korelasi fitur menunjukkan hubungan yang kuat antara harga penutupan dengan variabel harga lainnya, sementara volume memiliki hubungan moderat. Analisis risiko menggunakan pengembalian harian mengidentifikasi volatilitas signifikan, yang menjadi tantangan dalam pengambilan keputusan investasi. Penelitian ini menyimpulkan bahwa model SVM efektif dalam memprediksi tren harga Bitcoin. Namun, analisis risiko tetap penting untuk mendukung strategi investasi yang lebih bijaksana.    

Rapid advances in information technology have fuelled the emergence of digital currencies such as Bitcoin as an increasingly popular means of transaction in Indonesia. However, behind the convenience and speed offered, the use of Bitcoin also poses a high risk of fraud in online transactions. The main objective of this research is to analyse the nature of legal protection for Bitcoin users in Indonesia. This research applies normative juridical method with statutory approach, conceptual approach, case study analysis, and refers to legal protection theory, online transaction theory, and legal economic theory. One of the case studies studied is the High Court Decision 1240/Pid.Sus/2022/PN Tng which reflects the existence of a vacuum and vagueness of legal norms in the protection of Bitcoin users. The analysis shows that although Bitcoin has been regulated under the legal framework of digital asset trading, there are still inefficiencies in the application of legal protection in a comprehensive and effective manner. This research emphasises the need for more progressive regulatory reforms, as well as strengthening the role of law enforcement agencies and financial technology supervisors to ensure fair, certain and comprehensive protection for Bitcoin users in the territory of Indonesia. It is hoped that the results of this research can strengthen theoretical contributions in enriching the development of digital economy law and become a practical reference for policy makers.

Securities companies are one of the key pillars in the capital market system. The performance of securities companies can be influenced by dynamic market conditions, particularly the fluctuations of Bitcoin, Indonesia Composite Index (ICI), and gold prices. This study aims to analyze the influence of Bitcoin, ICI, and gold prices on the financial performance of securities companies in Indonesia. The financial performance is measured using the profitability ratio, Net Profit Margin (NPM). The sample consists of quarterly secondary data from 24 securities companies that meet the research criteria during the 2021–2024 period. The analytical method used is multiple linear regression after passing classical assumption tests. The results show that gold prices have a negative and significant effect on the NPM of securities companies, while Bitcoin and ICI had no effect. This indicates that an increase in gold prices tends to be followed by a decrease in the NPM of securities companies, and vice versa. This research is expected to assist the management of securities companies in formulating business strategies and risk management that are more responsive to fluctuations in Bitcoin, ICI, and gold prices.  

This study examines the status of Bitcoin and its underlying blockchain technology from the perspective of Islamic law. The research utilizes a qualitative library-based method, analyzing primary sources of Islamic jurisprudence alongside recent academic studies. It explores key Shariah principles such as mal mutaqawwam, maysir, gharar, and riba, in assessing Bitcoin's permissibility. The findings reveal that while Bitcoin's volatility, speculation, and lack of intrinsic value raise concerns under Islamic finance, the asset does not inherently involve interest (riba). Furthermore, the research distinguishes between the controversial nature of Bitcoin and the positive potential of blockchain technology, which aligns with the objectives of maqasid al-shariah, particularly in promoting transparency, financial inclusion, and ethical conduct. The study concludes that while Bitcoin may remain contentious, blockchain offers significant opportunities for Shariah-compliant financial innovation when supported by appropriate regulation and ethical oversight.

Global economic uncertainty has raised concerns among the public, triggering actions to secure economic stability by investing, especially in gold and bitcoin. This study uses a comparative quantitative method, with the aim of comparing the returns, risks, and performance of the two investment instruments. The population in this study is in the form of data on the monthly closing prices of gold and bitcoin for the period of January 2019 – April 2025 which totals 152 data, consisting of 76 data from each variable. Data analysis was carried out by calculating returns, risks, Sharpe, Treynor and Jensen indices. The three indices are widely used performance measurement methods and have included return and risk factors in their measurements. The results of this study show that there is a significant difference between the return of gold and bitcoin, while for the risk variable between the two, there is no significant difference. Performance based on the Sharpe method also showed no significant difference between the two. However, for performance measurement using the Treynor and Jensen methods, significant differences were obtained between the two instruments. Overall, bitcoin offers higher profit potential than gold, even more so for investors who can accept high volatility. However, the decision to choose an investment instrument still depends on the risk profile of each investor.

Cryptocurrency in Indonesia has begun to develop and is starting to be widely used by businessmen in Indonesia. This is a phenomenon given the need for accounting treatment for cryptocurrency transactions. This research seeks to explore and test cryptocurrency and blockchain technology with the approach and review of PSAK in Indonesia and focuses on accounting treatment for cryptocurrencies in Indonesia. The purpose of this study is to conduct an accounting study for cryptocurrencies based on PSAK that applies in Indonesia. The study used a review literature model to figure out accounting for cryptocurrencies.

The rapid development of technology has facilitated daily human activities, one of which is the existence of digital financial systems for transactions and investments, with Bitcoin being one of the products of digital currency. The purpose of this research is to carefully examine and analyze the role of digital forensics in efforts to trace the proceeds of corruption crimes that have been converted into Bitcoin. The legal research method used is a normative juridical approach, conducting research on library materials and utilizing the Statute Approach and Case Approach. The results of the research conclude that digital forensics is an important process in legal investigations involving the identification, collection, analysis, and preservation of digital evidence from electronic devices.

Cryptocurrency users, including those utilizing Bitcoin, Litecoin, Dogecoin, and others, are increasingly prevalent in Indonesia. Since the Rupiah is the only legal currency in Indonesia, cryptocurrencies cannot be used as a means of payment or exchange in financial transactions within the country. However, cryptocurrencies are considered investments when incorporated into commodities, becoming crypto assets that can be used as digital investment assets. This research employs normative legal research to explore legal principles and norms to address legal questions. If someone exchanges assets obtained from criminal activities for crypto assets, thinking they are legitimate, and if the money in these crypto assets is derived from criminal proceeds, such actions constitute money laundering (ML). This process involves purchasing crypto assets with illicit gains, exchanging Rupiah for cryptocurrency, or converting Rupiah into cryptocurrency. While cryptocurrency is recognized as a legal digital commodity for investment purposes in Indonesia, it becomes illegal when misused by individuals seeking to legitimize wealth obtained illegally. Converting illegally acquired wealth into cryptocurrency to deceive the government and make the transaction appear lawful may result in legal consequences

The integration of blockchain technology and cryptocurrency within the framework of Islamic finance has raised significant ethical, legal, and regulatory concerns. Blockchain technology, known for its transparency, decentralization, and immutability, offers a promising solution for enhancing financial inclusion, transparency, and security in financial transactions. However, the use of cryptocurrencies, such as Bitcoin and Ethereum, introduces complexities due to their speculative nature, which may violate Sharia principles like gharar (excessive uncertainty) and riba (usury). This study explores the compatibility of blockchain and cryptocurrency with Sharia law, focusing on the challenges and opportunities that arise in the context of Islamic finance. The study analyzes existing fatwas (Islamic legal opinions), regulatory frameworks, and the application of Sharia principles to emerging financial technologies. It discusses the ethical dimensions of blockchain and cryptocurrency, such as their potential to promote fairness and transparency, while addressing concerns about privacy violations and the risks associated with unregulated trading. Furthermore, the research highlights the lack of standardized global regulations for cryptocurrency and blockchain, which complicates their adoption in Muslim-majority countries. The study also emphasizes the importance of establishing Sharia-compliant governance frameworks and regulatory standards to ensure the ethical use of these technologies. Finally, the study provides recommendations for further research in the intersection of Islamic law, digital finance, and global governance frameworks, focusing on the development of policies that ensure Sharia-compliant digital assets and technologies.

This study aims to analyze the effect of the cryptocurrency market on the performance stock market. It considers IDX Composite as dependent variable while monthly price and volume Bicoin as independent variables and monthly inflation and the Bank Indonesia benchmark interest rate (BI Rate) as controlled variables from January 2018 to May 2024. Applying multiple linear regression model. The results of the study indicate that Bitcoin price has positive impact on the performance of stock market while it notices a negative impact on the same of the volume. Both Inflation and BI Rate also has positive impact on the performance stock. This research provides empirical evidence of the relationship between the cryptocurrency market and the stock market in Indonesia, as well as providing implications for investors, regulators, and academics.
