5 myths about Bitcoin and other cryptocurrencies.

The Myth:
The Price of Bitcoin and Other cryptocurrencies is a Bubble That Could Burst Anytime, Similar to the Dotcom Bubble in 2000.

The Truth:
Bitcoin and many other cryptocurrencies have indeed experienced spectacular price gains in the past, but they’ve also faced equally dramatic crashes. However, there are several reasons why cryptocurrencies shouldn’t simply be dismissed as a bubble. Despite their volatile nature, there are numerous real-world applications that make digital currencies much more than just speculative assets.

One example is their use for international money transfers, which can save both time and money. Traditional financial service providers often charge high fees and take several days to process cross-border transactions. Cryptocurrencies, on the other hand, enable fast and cost-effective transactions that can be settled directly between parties, without the need for banks or third parties.

Furthermore, an increasing number of businesses and institutions, especially Bitcoin, are accepting cryptocurrencies as a form of payment, further enhancing their legitimacy and acceptance. This growing use in the real world demonstrates that cryptocurrencies can offer genuine utility and value, extending beyond pure speculation.

The Myth:
Since cryptocurrencies are not controlled by any central authority, they are often used for illegal activities, such as money laundering, fraud, and arms or drug trafficking.

The Truth:
As with any other form of payment, cryptocurrencies are occasionally used for illegal transactions. However, it is important to emphasize that the most commonly used payment method for illegal activities is still cash – specifically, the U.S. dollar (USD). Around 2–5% of global GDP is estimated to be laundered annually while only about 0.4% of cryptocurrency transactions are classified as such. This suggests that cash is much more anonymous compared to cryptocurrencies.

One key reason for this is that all cryptocurrency transactions are recorded on the blockchain, which is publicly accessible. In contrast, cash offers greater anonymity as there are no transaction records. Nevertheless, most cryptocurrencies are actively working to improve the security and transparency of their transactions in order to combat illegal activities and build user trust.

The Myth:
As digital payment systems, cryptocurrencies are susceptible to cyberattacks and can be easily hacked.

The Truth:
In the past, the media has repeatedly reported on hacks of crypto assets. However, these incidents were mostly due to human error or vulnerabilities in the security infrastructure. In general, cryptocurrencies are considered safer than traditional financial instruments because they are based on a decentralized blockchain infrastructure (DLT). This structure makes it difficult for attackers to manipulate or disrupt the system.

By using secure offline wallets and keeping passwords safe, you can significantly reduce the risk of hacks. It is highly unlikely that you will become a victim of hacks if you follow these proven security practices.

The Myth:
Cryptocurrencies payments are not managed by any central authority, and transactions cannot be traced back to the user who made them. Therefore, they are anonymous.

The Truth:
Unlike bank payments, cryptocurrency transactions do offer a certain degree of anonymity. After all, every bank knows its customers, and every payment is linked to a person’s or company’s name. However, for cryptocurrency payments, no personal information about the payer or payee is required. Still, cryptocurrency transactions are not fully anonymous. Each transaction has a unique identification number and is recorded on the publicly accessible blockchain. This is referred to as pseudo-anonymity, meaning that a user operates under an alias or username rather than their actual name.

The Myth:
Cryptocurrencies consume a large amount of energy, which is often derived from fossil fuels. As a result, they are responsible for significant CO₂ emissions.

The Truth:
Some cryptocurrencies, particularly Bitcoin, have been criticized for their relatively high energy consumption. However, recent studies show that more than 50 % of Bitcoin’s mining energy now comes from sustainable or low-carbon sources such as hydro, wind, and nuclear power. In addition, many newer cryptocurrencies use Proof-of-Stake, a consensus mechanism that requires only a fraction of the energy of traditional Proof-of-Work. Ethereum, for example, reduced its energy use by over 99 % after its 2022 switch to Proof-of-Stake.

Although the environmental impact of cryptocurrencies has improved significantly, there is still potential to further reduce the carbon footprint. The industry is aware of this challenge and is actively working on solutions, including greater integration of renewable energy sources.

It shows that while many of the prejudices against cryptocurrencies and Bitcoin may contain a kernel of truth, they can often be debunked upon closer examination.
