Historical Background of Cryptocurrencies
The idea of digital currencies has been around for decades, but the true breakthrough came with the launch of Bitcoin in 2008 by an anonymous person or group known as "Satoshi Nakamoto." Since then, the world has witnessed a massive evolution in this field, with Bitcoin becoming the most famous cryptocurrency and the foundation for thousands of other coins based on blockchain technology.
What Are Cryptocurrencies?
Cryptocurrencies are virtual assets that use cryptographic techniques to secure financial transactions, operating on decentralized networks based on blockchain technology. These currencies are not issued by any central bank or government but are created and managed by networks of users worldwide.
Examples: Bitcoin, Ethereum, Litecoin, and others.
Blockchain Technology: The Backbone of Cryptocurrencies
Blockchain technology is a distributed digital ledger that records transactions between users, stored in "blocks" linked and protected by cryptographic techniques. This technology ensures transparency, security, and decentralization, as there is no central authority controlling the network.
"Blockchain technology enables peer-to-peer transfer of cryptocurrencies without the need for an intermediary like a bank or central authority."

Types of Cryptocurrencies
- Cryptocurrencies: Such as Bitcoin, Ethereum, Litecoin, etc.
- Stablecoins: Such as Tether, USD Coin, which are pegged to a currency or commodity.
- Central Bank Digital Currencies (CBDCs): Digital currencies issued by central banks.
How Cryptocurrencies Work
Cryptocurrencies rely on a network of nodes that verify and record transactions on the blockchain. Each transaction is encrypted and secured by complex mathematical algorithms, making it difficult to counterfeit or hack.
Some cryptocurrencies, such as Bitcoin, are "mined," where miners solve complex mathematical problems to secure the network and record transactions, receiving rewards in the form of digital coins.
The Importance of Cryptocurrencies in the Global Economy
Cryptocurrencies offer significant opportunities to enhance the global economy, especially in e-commerce and financial transfers. By reducing transaction costs and speeding up processes, companies can improve efficiency and increase profits. Cryptocurrencies also provide new investment opportunities, as individuals and businesses can invest in these currencies or use them as a hedge against economic volatility.
Cryptocurrencies face major challenges such as high volatility, security threats, and the need for advanced technological infrastructure to ensure financial system stability.
The Impact of Cryptocurrencies on the Financial System
Cryptocurrencies are transforming the global financial system by providing decentralized alternatives to traditional financial systems that rely on intermediaries. Cryptocurrencies do not require intermediaries such as banks or governments to execute transactions, reducing costs and improving speed. This decentralized model increases transparency and reduces corruption, as all transactions are recorded in a public ledger known as the "blockchain."
Risks and Challenges
- High Volatility: Cryptocurrencies experience sharp price fluctuations, making them risky for investors.
- Lack of Regulation: Many countries have not regulated the cryptocurrency market, exposing investors to fraud.
- Security Threats: Such as hacking, loss of encryption keys, and payment system failures.
- Liquidity Risks: Some cryptocurrencies may not provide sufficient liquidity for users.
- Illegal Uses: Such as money laundering and terrorism financing due to anonymity and ease of cross-border transfers.
The Future: Trends and Expectations for 2025 and Beyond
Forecasts indicate that institutional investment in cryptocurrencies will increase significantly, with major institutions continuing to inject more funds, bolstering the status of currencies like Bitcoin and Ethereum. The decentralized finance (DeFi) sector is expected to grow substantially, with a potential market value exceeding $100 billion.
Central bank digital currencies (CBDCs) are also expected to make gradual progress, which could impact market dynamics between decentralized cryptocurrencies and government-backed digital currencies.
Stablecoins such as Tether and USD Coin will continue to play a major role in facilitating cross-border transactions and providing stability in volatile markets.
Legal and Regulatory Perspectives
Cryptocurrencies have raised numerous legal and regulatory issues, as there is a lack of comprehensive studies on their legal status. There is a need for comprehensive legal adaptation to address all their aspects and implications, especially as demand grows and transactions worth millions of dollars are conducted daily.
Key legal concerns include risk (gharar), lack of clarity regarding origin, and the potential for illegal activities.
