Cryptocurrency mining dangers
As already mentioned before, cryptocurrency transactions use encryption to secure the blocks of data. Also, these blocks are immutable, which means that once created, no one can modify or tamper with the transaction record.
Therefore, it is almost impossible to hack the blockchain and change the transaction records. Currently, whenever a miner validates a block of bitcoin transactions, they gain a reward of 6. Approximately every four years, this reward gets halved, in a process known as Bitcoin halving. The next Bitcoin halving will occur in , which will decrease the reward amount to 3. Crypto mining is responsible for the creation and distribution of a cryptocurrency. Therefore, you can conclude that cryptocurrency is a self-sufficient currency.
Dangers of Crypto Mining Keeping aside the overall market cap of cryptocurrencies, some dangers associated with cryptocurrencies are also present, which are often neglected by people. Excessive Power Consumption Since mining cryptocurrencies is a complicated process, it requires a great deal of energy for running computers that consistently validate the blocks. With an increase in the price of cryptocurrencies, more and more people join the network, increasing the total energy consumption.
According to a University of Cambridge study, bitcoin mining requires more than Terrawatt hours of energy each year, not to mention that the numbers are continuously growing. Some countries have imposed a ban on mining cryptocurrencies , considering the heavy resources required for the process. Several environmental-friendly cryptocurrencies are also available in the market that claim to be green Bitcoin alternatives.
Cryptojacking The ever-increasing value of cryptocurrencies has attracted not only new miners but also hackers. Multiple cryptocurrency hacks have been reported in the past decade. Not only this, cybercriminals are now infecting personal computers to take advantage of their resources to mine cryptocurrencies, also known as cryptojacking. Many hackers install JavaScript-based scripts on computers that mine cryptocurrencies for them in the background. Instead, they utilize a smaller portion to mine slowly and steadily for a longer period of time.
According to the McAfee blog , 50 out of every , devices have experienced cryptojacking in one way or another. Cryptocurrencies Are Volatile As the price of cryptocurrencies skyrocket, many people get fascinated by the idea of this "get-rich-quick" scheme which often leads them nowhere. Not everyone takes the volatility and risks of cryptocurrencies into consideration and invests more funds than they should.
Also, miners, who spend thousands of dollars every month on electricity bills, don't know that they might be taking a shot in the dark. Since there is no guarantee on the returns, investing in cryptocurrencies can be dangerous if not given proper thought. Not really a "danger," but the implication is still large enough to consider.
In and , the demand for mining hardware and the global semiconductor chip shortage pushed prices even higher, with GPUs trading for thousands more than their MSRP. Can Anyone Start Mining Cryptocurrencies? Crypto mining is a flexible process that anyone can perform. You can even set up systems to mine cryptocurrencies from your home. Some countries have restrictions on mining, and it is crucial to keep track of the new regulations associated with cryptocurrencies in your country.
Crypto miners need to submit a PoW, or Proof of Work, stating that they have successfully validated the current block. Unlike physical money, cryptocurrencies are decentralized, which means they are not issued by governments or other financial institutions. Cryptocurrencies are created and secured through cryptographic algorithms that are maintained and confirmed in a process called mining, where a network of computers or specialized hardware such as application-specific integrated circuits ASICs process and validate the transactions.
The process incentivizes the miners who run the network with the cryptocurrency. Bitcoin, for instance, was created by Satoshi Nakamoto pseudonym and released in as open-source code. Blockchain technology made it all work, providing a system where data structures blocks are broadcasted, validated, and registered in a public, distributed database through a network of communication endpoints nodes. While bitcoin is the most famous cryptocurrency, there are other popular alternatives.
This resulted in the development of Ethereum Classic, based the original blockchain, and Ethereum, its upgraded version via a hard fork. Litecoin is a purportedly technical improvement of Bitcoin that is capable of faster turnarounds via its Scrypt mining algorithm Bitcoin uses SHA The Litecoin Network is able to produce 84 million Litecoins—four times as many cryptocurrency units issued by Bitcoin.
Monero is notable for its use of ring signatures a type of digital signature and CryptoNote application layer protocol to protect the privacy of its transactions—amount, origin, and destination. Dogecoin, which was initially developed for educational or entertainment purposes, was intended for a broader demographic.
Capable of generating uncapped dogecoins, it also uses Scrypt to drive the currency along. Given their nature, they are more secure from fraud and identity theft as cryptocurrencies cannot be counterfeited, and personal information is behind a cryptographic wall.
Unfortunately, the same apparent profitability, convenience, and pseudonymity of cryptocurrencies also made them ideal for cybercriminals, as ransomware operators showed. The increasing popularity of cryptocurrencies coincide with the incidences of malware that infect systems and devices, turning them into armies of cryptocurrency-mining machines.
Cryptocurrency mining is a computationally intensive task that requires significant resources from dedicated processors, graphics cards, and other hardware. While mining does generate money, there are many caveats. Cryptocurrencies are mined in blocks; in bitcoin, for instance, each time a certain number of hashes are solved, the number of bitcoins that can be awarded to the miner per block is halved.
Since the bitcoin network is designed to generate the cryptocurrency every 10 minutes, the difficulty of solving another hash is adjusted. And as mining power increases , the resource requirement for mining a new block piles up. Payouts are relatively small and eventually decrease every four years—in , the reward for mining a block was halved to Consequently, many join forces into pools to make mining more efficient.
Profit is divided between the group, depending on how much effort a miner exerted.
