Monday marked the seventh anniversary of the first recorded transaction of the popular cryptocurrency, Bitcoin.Seven years ago a single bitcoin was worth $0.003, and today it is going for a whopping $2,300.That day is celebrated as Bitcoin Pizza Day.bitcoin stock market ticker7 years ago, a transaction was made by a programmer named Laszlo Hanyecz who spent 10,000 bitcoins on two pizzas.bitcoin betting redditHe asked a fellow enthusiast on a forum to accept 10,000 bitcoins in exchange for the pizzas.litecoin miner saleThe bitcoins spent on those two pizzas are now worth over $22.5 million.bitcoin historical calculatorSince its first transaction, the value of a bitcoin has increased tremendously, multiplying by 879,999 times.bitcoin wiki coinbase

Anyone who invested on $100 worth of bitcoins back then would now have earned over $75 million.Of late, bitcoins’ value has surged thanks to a new law in Japan which accepted it as a legal currency and has boosted its trade in Japanese yen.bitcoin jackpot reviewOver 40 percent of bitcoin trade is now carried out in the country.ethereum simple explanationPolitical unrest is another factor which has increased investment in bitcoins as it’s considered a safe asset than standard currency or stocks.bitcoin cape townDuring the recent past, there was a debate in the bitcoin community regarding the underlying technology used in blockchains to mine the currency.bitcoin ubsIt led some to believe that bitcoin will be split into two currencies however that has changed and a more realistic alternative has been put forward, increasing investor interest yet again.

Bitcoins are earned either through payments or through mining, which involves a complex mathematical solution where the miner is rewarded in bitcoins.Right now, bitcoin is worth about $2,312 and its rapid recent growth is hinting at a new, higher settling point for the cryptocurrency.The currency still isn’t recognized by most governments and its critics point out to the fact that it is used for transactions by criminals like the recent Windows ransomware which called people to pay in bitcoins or have their data removed.However, that hasn’t stopped investments and it continues to gain traction throughout the globe.The value of bitcoin continues to vary, but consider this – 7 years ago, if only you had spent Rs.50 on Bitcoins, you’d now have Rs.4.4 crore in your pocket!Hackers may be hijacking internet-connected fridges, toasters and light bulbs in order to use their computing power to mine bitcoins, researchers have revealed.IBM researchers discovered a bitcoin mining component in a new variant of Mirai—a form of malware that exploits security vulnerabilities to take control of devices connected to the so-called Internet of Things (IoT).Security firm McAfee recently estimated that more than 2.5 million IoT devices were infected by the Mirai botnet in 2016, though it is not clear how many compromised devices may have been used to mine the virtual currency.

Tech & Science - Get the best of Newsweek delivered to your inbox“We do not have any insight into whether or not bitcoins were actually mined during these attacks,” Dave McMillen, a senior threat researcher at IBM, tells Newsweek.“It is also not known whether or not this is the actions of one group or many… This Mirai variant could be appealing to others in the future due to the potentially large volume of devices that could be involved.”Security experts have previously warned that hackers could target smart devices in order to mine bitcoin.Mikko Hypponen, chief research officer at F-Secure prophesied in 2014 that cryptocurrencies offered a new method for criminals to profit from vulnerable devices.“Attacks don’t target the user but the computer itself,” Hypponen said.“Internet of Things devices can be hacked to mine cryptocurrencies and make money.”Mining bitcoin—the process of confirming bitcoin transactions and adding their record to bitcoin’s public ledger in order to generate new units of the currency—requires vast amounts of computing power.

It would therefore require a huge network of IoT devices in order to have a successful mining operation.Details of the Mirai variant were published by the IBM researchers in an online blog, in which they speculated hackers would be incentivized to mine for bitcoin in order to facilitate cybercriminal activities.According to a 2016 study by the security firm BullGuard, up to 185 million devices may be at risk of being compromised by Mirai.Hackers used the network of compromised devices in a series of attacks that caused several major websites to go offline, including Netflix, Reddit and Twitter.Projections from technology research firm Gartner suggest the issue may escalate if security fixes are not implemented by device manufacturers.According to Gartner, there will be more than 20 billion IoT devices by 2020, while estimates from ABI Research put the figure closer to 30 billion.Cybersecurity experts warn that too many manufacturers treat security as an afterthought when producing internet-enabled devices.Chris Boyd, an analyst at the security firm Malwarebytes, told Newsweek in an interview last year: “The problem here is that many IoT devices are horribly broken security-wise because it costs money to ensure a reasonable standard of protection on a product.”This lax approach will inevitably lead to much more devastating attacks, according to cybersecurity veteran John McAfee.“The attacks are slowly escalating, similar to the way America developed the atomic bomb,” McAfee, who created the eponymous antivirus computer software but is now longer connected to it, said in October.
