Cryptocurrencies have become a popular tool with criminals for nefarious activities such as money laundering and illicit purchases. The case of Dread Pirate Roberts, who ran a marketplace to sell drugs on the dark web, is already well known. Cryptocurrencies have also become a favorite of hackers who use them for ransomware activities.

Cryptocurrency mining might sound like something you do with a shovel and a hard hat, but it’s actually more like accounting. Miners are nodes that perform a special task that makes transactions possible. I’ll use an example to show you how it works using the Bitcoin network.

Buying cryptocurrencies is the most common way to acquire them. This can be done through cryptocurrency exchanges, which are platforms that facilitate the buying, selling, and trading of cryptocurrencies, where users can exchange fiat currency (like USD, EUR) for cryptocurrencies. Some popular places to buy include the Crypto.com App and Crypto.com Exchange.

As a result, most crypto holders have shifted their attention to the investment potential of cryptocurrencies, which has since birthed the speculative side of the crypto market. Investors seem to be more concerned about the possibility that the price of a cryptocurrency may rise sometime in the future than whether they can use cryptocurrencies to purchase goods and services, and so crypto is now predominantly viewed as an investment.

This infrastructural design makes it possible for cryptocurrencies to evade the security mishaps that often plague fiat. It is difficult to attack or manipulate this system because the attackers must gain control of over 50% of computers connected to the blockchain network. Depending on how big the network is, it can be prohibitively expensive to carry out a coordinated attack. If you compare the amount required to attack established cryptocurrencies like bitcoin and what the attacker stands to gain at the end of the day, pursuing such an endeavor wouldn’t be viable financially.

Over the past few decades, consumers have become more curious about their energy consumption and personal effects on climate change. When news stories started swirling regarding the possible negative effects of Bitcoin’s energy consumption, many became concerned about Bitcoin and criticized this energy usage. A report found that each Bitcoin transaction takes 1,173 KW hours of electricity, which can “power the typical American home for six weeks.” Another report calculates that the energy required by Bitcoin annually is more than the annual hourly energy usage of Finland, a country with a population of 5.5 million.

Cryptocurrencies promise to make transferring funds directly between two parties easier without needing a trusted third party like a bank or a credit card company. Such decentralized transfers are secured by the use of public keys and private keys and different forms of incentive systems, such as proof of work or proof of stake.

In February 2014, the world’s largest bitcoin exchange, Mt. Gox, declared bankruptcy. Likely due to theft, the company claimed that it had lost nearly 750,000 bitcoins belonging to their clients. This added up to approximately 7% of all bitcoins in existence, worth a total of $473 million. Mt. Gox blamed hackers, who had exploited the transaction malleability problems in the network. The price of a bitcoin fell from a high of about $1,160 in December to under $400 in February.

A 2020 EU report found that users had lost crypto-assets worth hundreds of millions of US dollars in security breaches at exchanges and storage providers. Between 2011 and 2019, reported breaches ranged from four to twelve a year. In 2019, more than a billion dollars worth of cryptoassets was reported stolen. Stolen assets “typically find their way to illegal markets and are used to fund further criminal activity”.

Fiat currencies derive their authority from the government or monetary authorities. For example, the U.S. dollar is recognized and issued by the government as the official currency of the United States and is “legal tender.”
