The Dangers of Cryptocurrency: Ecology, Scams, Volatility, Illicit Activities, and Concentration of Power


Cryptocurrency raises major concerns in various areas. This article explores the challenges and dangers associated with cryptocurrency, focusing on five key points: ecological impact, scam risks, price volatility, use in illicit activities, and concentration of power. We substantiate our arguments with relevant examples and credible sources to illustrate the underlying issues that require thoughtful consideration.

Devastating Ecological Impact

Cryptocurrency, particularly Bitcoin, faces increasingly intense criticism due to its considerable ecological footprint. The mining process, which secures and validates transactions, requires high computational power and, as a result, massive energy consumption. According to a study published in the journal “Nature,” Bitcoin mining could emit as much CO2 as certain major cities by 2024.*

Another striking example is the use of energy in Iceland for cryptocurrency mining. Due to its abundant and inexpensive electricity, Iceland has become a major center for Bitcoin extraction. However, this has also led to a significant increase in the country’s energy consumption, jeopardizing its renewable energy supply.**

Risks of Scams and Frauds

One of the major dangers of cryptocurrency lies in the proliferation of scams and frauds. Scammers take advantage of the relative anonymity and technical complexity of blockchain technology to lure uninformed investors. A notable example is the OneCoin case, which deceived thousands of people by offering a fictitious cryptocurrency. The founders managed to collect billions of dollars before being arrested.*

Another notorious case is that of BitConnect, an investment program based on a cryptocurrency that promised extraordinary returns. However, it turned out to be a pyramid scheme, where early investors were rewarded with money from new participants. When the system collapsed, thousands of people lost their savings.**

Extreme Volatility

Extreme volatility is an inherent characteristic of cryptocurrency, making it a highly risky financial asset. Prices can vary significantly within a matter of hours, or even minutes, resulting in dramatic gains or significant losses. A striking example is the cryptocurrency market crash in 2018, where many cryptocurrencies lost over 80% of their value in a few months.*

Another example is the sudden and unpredictable surge in the price of Dogecoin in 2021. This cryptocurrency, which was originally created as a joke, experienced a surge in popularity due to tweets from influential figures. However, once the hype subsided, the price dropped significantly, leaving many investors in a difficult situation.**

Use in Illicit Activities

The pseudonymous nature of cryptocurrency has raised concerns about its use in illicit activities, such as money laundering and financing terrorism. Cryptographic transactions provide a certain level of confidentiality, making it more challenging to trace funds. A notorious example is the Silk Road case, an online platform that facilitated the illegal trade of drugs using Bitcoin as a payment method.*

Another case is that of Ransomware-as-a-Service (RaaS), where criminals utilize cryptocurrencies to demand ransoms in exchange for unlocking data captured by malware. These illegal activities have experienced rapid growth in recent years, partly fueled by the ease of cryptographic transactions.**

Concentration of Power

Another major issue associated with cryptocurrency is the concentration of power. In some cases, a small number of key players can exert disproportionate influence over the markets. For example, holding a significant amount of cryptocurrency by a single entity can manipulate prices and result in artificial volatility.*

An example is the exchange platform Binance, which has become one of the largest cryptocurrency platforms in terms of trading volume. Binance’s strong influence on the cryptocurrency market has raised concerns about the centralization of power and potential price manipulation.**


Cryptocurrency offers fascinating opportunities but is not without significant dangers. The challenges related to its ecological impact, scams and frauds, extreme volatility, use in illicit activities, and concentration of power require adequate attention and regulation. It is essential to raise awareness among users, promote transparency, and establish appropriate regulatory frameworks to ensure responsible adoption of blockchain technology. Only a balanced approach will maximize the benefits while mitigating the inherent risks of cryptocurrency.
