WIRED has been reporting on digital currency Bitcoin for several years, but in the past few months, a single bitcoin’s trading value has swung significantly making it a regular fixture in headlines. Despite this, there remains a lot of confusion about what bitcoins are, how to use them and whether or not we are in a Bitcoin Bubble. Here’s our simple guide to Bitcoin. Bitcoin is a peer-to-peer electronic cash system or “cryptocurrency” that doesn’t rely on trusting one central monetary authority and allows for anonymous, untrackable and untaxable transactions. Is it a commodity or a currency? It seems that Bitcoin is an awkward combination of the two. The commodity value of bitcoins is linked to their currency value, but the more they become like a commodity, the less useful they are a currency.
Lots of people might be working on the same unit of work – a computationally complicated problem. When it started out, it was relatively easy to mine bitcoins, but as more people are trying to get in on the action, it’s become computationally much more challenging — in the same way that it’s easier to find the early prime numbers, but harder now. The network is used to monitor and verify the creation of new bitcoins and all Bitcoin transactions, which are filed in a log. Can I just use my laptop? You can, but you are unlikely to mine any bitcoins. Because of how hard mining now is, it could take more than three years to generate any coins, running up huge energy and equipment costs.
There are plenty of opportunistic IT suppliers keen to sell you expensive equipment dedicated to mining. You can exchange regular currencies for bitcoins using an exchange. 80 per cent of Bitcoin trade, as around 45 percent of exchanges fail, taking their users’ money with them. Gox believes that opportunists are attacking exchanges to destabilise the market. Bitcoin is very useful if you want to buy drugs and other illegal items without easily being identified. You can spend them on online black markets such as Silk Road.
A 2012 study found that around 20 percent of all bitcoins exchanged on Mt. Beyond Silk Road, you can also spend bitcoins online at Reddit, WordPress and Mega but so far there aren’t so many places in meatspace that accept it yet, with the exception of a few bars with connections to the Bitcoin community. You can see a more comprehensive list of where to spend bitcoins here. Bitcoin maintains that because all transactions are trackable they are secure, but there have been a few cases where hackers have ransacked electronic wallets used to store secret keys that give you the right to spend your bitcoins, notably when one exchange had 25,000 stolen. Needless to say, there are some extremely smart hackers in Bitcoin. Harder mining also means that fewer people will bother dedicating the processing power to mining, which could mean that the overall number of nodes decreases to the point where it could be vulnerable to a 51 percent attack.
What is a 51 per cent attack? Bitcoin records every single transaction on its network in a public record called the blockchain. A new one is generated roughly every ten minutes and shared throughout the network. The determining factor in whether the blockchain is the real one or should be discarded as a fake is whichever is accepted by the most number of mining nodes. 76 within a very short space of time before rebounding again. Because of the lack of liquidity in the market and no central authority to influence supply and demand, the currency is vulnerable to speculation and manipulation.
A series of DDoS attacks against Mt. Gox was enough to send the Bitcoin value into freefall. Should I get into Bitcoin mining now? You can, however, still invest in Bitcoin as a speculator, with the hope of selling at a higher price. But go into it with open eyes. Certified by Lexcode Regulatory Compliance Technologies Pvt.
