Did You Buy Crypto Last Year? Here Are 6 Questions You Might Want to Ask Your Tax Pro
The Australian government has just recognized digital currency as a legal payment method. Since July 1, purchases done using digital currencies such as bitcoin are exempt from the country's Goods and Services Tax to avoid double taxation. As such, traders and investors will not be levied taxes for buying and selling them through legal exchange platforms.
Japan, which legitimized bitcoin as a form of payment last April, already expects more than 20, merchants to accept bitcoin payments. Other countries are joining the bandwagon, albeit partially: businesses and some of the public organizations in Switzerland, Norway , and the Netherlands.
In a recent study , unique, active users of cryptocurrency wallets are pegged between 2. But what does the acceptance and adoption of digital currencies have to do with online threats?
A lot, actually. As cryptocurrencies like bitcoin gain real-world traction, so will cybercriminal threats that abuse it. But how, exactly? What does this mean to businesses and everyday users? Cryptocurrency is an encrypted data string that denotes a unit of currency. It is monitored and organized by a peer-to-peer network also known as a blockchain, which also serves as a secure ledger of transactions, e.
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. There are also other notable cryptocurrencies: Litecoin, Dogecoin, Monero. 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. Bad guys turn to using malware to skirt around these challenges. To offset this, cryptocurrency-mining malware are designed to zombify botnets of computers to perform these tasks. Cryptocurrency-mining malware employ the same modus operandi as many other threats—from malware-toting spam emails and downloads from malicious URLs to junkware and potentially unwanted applications PUAs.
In January , a vulnerability in Yahoo! In , the threat crossed over to Android devices as Kagecoin , capable of mining bitcoin, litecoin, and dogecoin. The same was done to an old Java RAT that can mine litecoin. All exploit vulnerabilities. These threats infected devices and machines and turned them into monero-mining botnets. Cryptocurrency-mining malware steal the resources of infected machines, significantly affecting their performance and increasing their wear and tear.
An infection also involves other costs, like increased power consumption. The most prevalent of these attacks we saw were:. Information theft and system hijacking are also daunting repercussions. These attacks can also be the conduit from which additional malware are delivered. In April , a variant of Mirai surfaced with bitcoin-mining capabilities.
Over the first three quarters of , we detected a bitcoin-mining zombie army made up of Windows systems, home routers, and IP cameras. From January 1 to June 24, , we also observed different kinds of devices that were mining bitcoin, although our telemetry cannot verify if these activities were authorized.
We found that machines running Windows had the most bitcoin mining activities, but also of note are:. Cryptocurrency-mining malware can impair system performance and risk end users and businesses to information theft, hijacking, and a plethora of other malware.
And by turning these machines into zombies, cryptocurrency malware can even inadvertently make its victims part of the problem. There is no silver bullet for these malware, but they can be mitigated by following these best practices:. Proactively monitoring network traffic helps better identify red flags that may indicate malware infection.
Original design and equipment manufacturers also play vital roles in securing the ecosystems they run in. Like it? Add this infographic to your site: 1. Click on the box below. Internet of Things. Securing Home Routers.

The debate about cryptocurrency and energy consumption
Block founder and CEO Jack Dorsey just confirmed that the company, formerly known as Square, plans to move forward with plans to build a bitcoin mining system. The company first announced that it was considering the project in October. The project's goal is to make mining bitcoin, the largest cryptocurrency by market value, "more distributed and efficient," tweeted Thomas Templeton , the company's general manager for hardware. Bitcoin operates on a proof of work PoW model, where miners must compete to solve complex puzzles in order to validate transactions. The process isn't easy: It requires a lot of energy and computer power, which isn't cheap. The computers themselves, along with other equipment, can also be very expensive. Templeton mentioned that there are a number of "customer pain points" and "technical challenges" in the mining community that Block hopes to address, including mining rig availability, high price, reliability and power consumption. Once you've managed to track them down, they're expensive and delivery can be unpredictable," Templeton tweeted. What can we simplify to make this a reality?

Cryptocurrencies such as Bitcoin or Dash are digital assets which use which use cryptographic techniques to verify the transfer of assets and control the creation of additional units of the crypto currency. The key feature of a cryptocurrency is that the ledger that records transactions, known as a blockchain, is not controlled by a central authority. Instead, each cryptocurrency implements a system where transactions on the blockchain are validated by a large number of independent parties. These independent parties who do the work of verifying transactions are known as cryptocurrency miners. These systems are set up so that crypocurrency miners are rewarded for mining with newly created units of the cryptocurrency such as Ethereum.
Bitcoin Mining: How long does it take to mine 1 bitcoin?
In the United States, cryptocurrencies have been the focus of much attention by both Federal and state governments. While there has been significant engagement by these agencies, little formal rulemaking has occurred. Many Federal agencies and policymakers have praised the technology as being an important part of the U.
Bitcoin mining is a process that verifies transactions on the blockchain ledger, while also bringing new bitcoins into circulation. To be successful at this, cryptominers require vast amounts of computing power, meaning electricity becomes one of their most significant costs. This pushes them to locate wherever electricity is cheapest. For years, China was the optimal location—the country has an abundance of cheap, coal-powered electricity. However, in September , the Chinese government issued a blanket ban on all crypto activities.
Subscriber Account active since. Bitcoin mining is a crucial part of the cryptocurrency's underlying technology through which transactions are verified and added to the digital ledger known as blockchain. The owners and operators of the computer systems that make up the decentralized Bitcoin network, called miners, receive newly created bitcoins as a reward for this work. In this process, miners compete to solve highly complex mathematical equations. The first to figure it out receives the reward. Bitcoin is a cryptocurrency, meaning that it is a currency that leverages cryptography.
