At the latest Satoshi Square event ter the City of London, it wasgoed said that 2014 will be the year for bitcoin mining, spil the crypto-currency is soon to reach a tipping point where creating it will no longer be possible for the average user.
Amid the hugely volatile price, its use for buying Class A drugs, and multimillion-dollar cyber heists, it’s sometimes effortless to leave behind where bitcoin came from, and how it and other crypto-currencies are created.
Mining is the term given to the process of producing virtual currencies like bitcoin and litecoin, where computers solve mathematical equations and are rewarded with coins for their efforts.
When bitcoin launched five years ago coins could be lightly mined using a huis rekentuig or laptop, but the currency is pre-programmed to make mining more difficult overheen time, resulting ter a situation now where only specially-made computers can mine efficiently.
Bitcoin may have grabbed all the crypto-currency headlines te 2013, but it’s far from alone. Litecoin is widely regarded spil the silver to bitcoin’s gold, and with a price of around 20 to 30 vanaf coin, it is substantially cheaper than the 500-plus bitcoin.
But with dozens of crypto-currencies available – including dogecoin – there are slew of options to choose from. And while some might be overlooked for being almost worthless – one dogecoin is equal to less than 0.01 – the come back on any investment made te the currency could be meaty.

When bitcoin wasgoed launched ter 2009, any regular laptop could be used to mine it. The process of solving mathematical equations wasgoed performed by the computers’ CPU (central processing unit), but spil the difficulty enhanced, mining through the CPU became unlikely and instead users recruited the toegevoegd power of their GPU (graphical processing unit).
From then on an arms wedstrijd developed, spil miners scrambled to produce more and more powerful computers with rows of graphics cards, such spil the high-end Radeon HD 7950 and Radeon 290X.
When creating your mining machine, feel free to bulk it up with reserve GPUs, but reminisce they can be very power requesting – with numerous graphics cards running at once, the right power supply will be significant to keep everything stable and running spil efficiently spil possible.
Other than a basic motherboard and spil many graphics cards spil you can afford, there isn’t much more to think about spil far spil hardware is worried, add a hard drive (but recall, your mined coins are not necessarily stored on here) and you’re good to go.
Spil the mining equipment has bot assembled from scrape, an operating system needs to be installed. This commonly means Windows, but Microsoft’s software is not best-suited to crypto-currency mining – and some members of the bitcoin community consider it to pose too much of a security risk to be trusted.
Instead, miners should consider the Linux operating system, for which a number of mining-optimised builds already exist, such spil BAMT and LinuxCoin – the former only works with litecoin, but both come with mining software included ter the operating system.
For other mining software – for Windows, Linux and Mac – visit bitcoin’s own Wikipedia-style webstek.
Once an operating system and mining programme have bot chosen and installed, next you will need a wallet te which to store your coins once they have bot mined. Rather than storing coins spil lumps of gegevens – like a digital photograph – you store encryption keys which give you access to the coins.
Instead of a hard drive containing, say, 100MB of bitcoins, you actually store a private key which tells the trading network how many coins you have – what your balance is.
It is the private key – a long list of letters and numbers – that is stored te your wallet, or written down on paper if you choose. If your private key is lost or stolen, then access to your coins is also gone forever.

Hot Wallet vs Cold Storage
A ‘hot wallet’ refers to a coin wallet which is connected to the internet – either by desktop laptop or smartphone – while cold storage refers to wallets kept on devices not connected to the internet, like a USB thumb drive.
Hot wallets are instantly available to the user, while cold storage wallets cannot be accessed or hacked into remotely overheen the web. Keeping a hot wallet with the private key to a large sum of bitcoins would be like walking outside with a phat wad of metselspecie ter your pocket – it’s safer to leave your money ter the bankgebouw and your bitcoin keys ter an offline ‘cold’ wallet.
Wallets can be made te three places – on your pc spil an application, spil a mobile app on your smartphone, or on the web, where it is stored by a third party.
Wallets stored on your laptop are susceptible to hacking spil they often leave your private key un-encrypted by default – spil hackers will know where to look, should they build up access to your PC, it is significant to encrypt the verkeersopstopping containing your key with a strong password.
Malware and keystroke loggers
However, a hacker using malware to track your keystrokes – and thus the passwords you inject while using your laptop – could still steal your coins. Basic practice here is significant: keep your antivirus software up-to-date and keep your wits about you.
An alternative to storing your wallet on your own laptop is the web-based wallet, such spil Blockchain.informatie. Thesis wallets function te a similar way except the encryption keys are stored on the service provider’s server, rather than your own rekentuig, thesis keys are encrypted and only accessible using your password.
Online wallets also offerande two-factor authentication, whereby any login attempt by you (or a potential thief) requires your password, plus access to your mobile phone which is sent a code to be entered while logging ter.
Eventually, Blockchain.informatie offers the use of a 2nd password, used for each bitcoin transaction you make (rather than the same spil used to loom into the wallet) and it is entered using your mouse and an on-screen keyboard to avoid keyloggers.
Keeping crypto-coins safe might sound like hard work, but given the dramatic rise te bitcoin’s value overheen the last 12 months, a few toegevoegd security stages will always be better than having your coins stolen with no way of getting them back.

Joining a mining pool or going it alone
Spil wij have already said, mining bitcoins is almost unlikely without a powerful, dedicated pc. Gratefully there is another option te the form of mining pools, where numerous users can contribute computing power to a single pool.
Because many computers are working together, coins are mined more quickly – but recall, the prizes will be collective across the pool.
Access to mining pools can be found at Multipool and Middlecoin, with the former taking a petite 1.5% cut of any coins you mine. Meantime, Middlecoin will use the power of your pc to automatically mine the most valuable alternative coins, the service then converts thesis into bitcoins and transfers them to your wallet.
That’s just about it – if you’re blessed mining dogecoin or some of the lower-valued crypto-currencies, then you don’t need to spend a gigantic amount on mining equipment. If, however, you want to earn big money mining bitcoins, then an outlay of ems of thousands of pounds will be needed to make a healthy profit ter a relatively brief time framework.
