Bitcoin Mining

Bitcoin is still in it's startup phase and this means that not all Bitcoin has been "digged up" yet so to say. Aside from the technical aspect of mining you can view it as giving away computer power at the expense of the Bitcoin network for a share of the new generated Bitcoin in return.

The way mining works today as in that miners join up to create mining pools, within these pools people work together to find so called Bitocoin blocks, which are today 25 Bitcoin each plus transaction fee's that users have paid.

So how do I mine ?

Before you start getting excited, I would like to say that the difficulty of Bitcoin mining increases everyday and unless you have special mining hardware, like Asic or FPGA based mining hardware, you will have a hard time getting a return on your investment.

That being said the way to mine with your computer is to GPU mine. This is using your graphics card in your computer to make calculations for the Bitcoin network. Mining works best on ATi Radeon HD cards in the 5,6 and 7000 series. Check your computer device manager so see what graphics card you have.

Setting your pc up:

You will need to download and install the latetst drivers for your graphics card.
ATI Cards here
Nvidia Cards here

You will need to download and install a program called GUIminer. (In later articles I will be discussing different mining software and setting up Asic hardware.)
Download here

You will have to register an account at a mining pool.
For example Triplemining

After you register an account navigate to the workers page and setup a worker username and password.

Now you will run the GUIminer software by clicking its Icon in your startmenu.

The options:

  • Server: Select your Pool in this list, in my example select Triplemining
  • Username: Here you will put in your worker name, not your pool username
  • Password: Here you will put in your worker password, not your pool password
  • Device: Here you will select your GPU, running ATi it will have a name of an island like Cayman
  • Extra Flags: "-v -f0" is good for any graphics card.
Now you are good to go, click start mining and see the magic happen.

How to buy Bitcoin. (And very usefull Trading Tips)

So you have your wallet setup and ready to go, and now you want to convert some of that worthless fiat money in your pocket to Bitcoin. Very wise decision.

In the past I have been buying Bitcoins at 2 traders.

#1 MtGox (Click to Visit)

#2 Bitstamp (Click to Visit)

And maybe there are some bright readers that have already seen that both websites have a different value (of about 10-12 USD). Yes you can buy at one trader and sell at the other for profit. I do not give any guarantee's as the Bitcoin value can fluctuate in seconds although this is unlikely to happen. I have tried it myself and the profit was about 15%.

Also I have noticed that when buying and selling Bitcoin, the prices seem to drop during the weekends. Why is this I can hear you thinking, that is because the normal FOREX and Stockmarkets close during the weekends. Anyone who is into professional trading will not be buying or selling any Bitcoins, which decreases the demand, which decreases the price.

How to get free Bitcoin !

Ofcourse there is mining for Bitcoin, but there are also various ways to get free bitcoins on the internet.
Most websites that offer free Bitcoins are called Bitcoin-faucets, these websites work like this: You visist the website, which has advertisements on it. After proving you are a human visitor by solving a captcha, you get a share of the website income payed out in Bitcoin. Rewards vary from site to site.

Then there are also games that offer free Bitcoin, although some of them require you to wager in some Bitcoin, these i don't concider free since you may lose some Bitcoins.

To start getting free bitcoins visit some of the faucets below, to check your balance visit Coinbox

Faucet 1
Faucet 2
Faucet 3

Then there is a really simple way to make some free bitcoins, its called the free bitcoin lottery. I'm guessing this website is also sponsored by advertisments. You can click 6 out of 50 numbers, then the numbers are reveiled, for every right guess you will receive some Bitcoin. I Have tried all of the websites I mentioned and can verify their payout.

How to buy illegal stuff with Bitcoin, Drugs and such

I would like to start this article by stating that I do not engange in the online blackmarkets, but as a Bitcoin guy I do know how to get there, and I believe that by allowing people to buy their illegal drugs direct from the source you can avoid a whole lot of criminality surrounding drugs. On a sidenote I believe the whole war on drugs is a big farce.

Anyway back to the topic, you want to buy whatever online and it is possible, Bitcoin allows you to pay completely anonymous, which has opened up a whole new type of online shopping.

What do you need:

  • A Computer (No shit ?)
  • Tor - Download Tor
  • Some Bitcoin to spend
Step 1: 

This is mandatory, you will not be able to connect to any blackmarkets from another browser

Installing TOR is pretty easy. You download the installer for your system on the previously linked page. After downloading it, execute it, follow the installation wizard. After installation Tor will automaticly start and open up a Firefox Window and state you are now anonymous

Step 2:

Now all you do is enter the onion link to the Silk Road in the newly opened TOR Browser window.
This is at the time of writing a working Silk Road link, but they are subject to change.
Paste this into the TOR browser: http://silkroadvb5piz3r.onion

Press Enter, and there you go, the world at your feet. I will not go into making an account and such, I assume you are not complete retards.

Setting up a Bitcoin Wallet, the safe way !

Now that you know what Bitcoin is, the first thing you want to do is get some!



I will get into detail about how to obtain (free) Bitcoin, but to get Bitcoin you first need a place to store them. This place is called a Bitcoin Wallet. They come in different shapes, sizes and flavours and all have their pro's and con's. I will try to explain the most commonly used Wallets and from here you should decide what suits you the best.

#1 Bitcoin-QT

Link: Download Bitcoin-QT

Bitcoin-QT is the original backbone of the Bitcoin Network. If you are looking for a secure wallet where you are fully responsible for your own Bitcoin then this is the Wallet for you. When used correctly this wallet offers you 100% security on your Bitcoin. Making back-up's of your Wallet is as easy as clicking Back-up wallet. Restoring a previously saved wallet is a bit more technical. And so is the overal use of this Wallet.

Pro's:
  • Secure
  • Support the network
  • Store your money localy
Con's:
  • Huge HDD space required since it downloads the complete blockchain
  • Not really (noob)user friendly
  • Forget your password or lose your wallet.dat file and you permanently lose all your Bitcoin


#2 Electrum


Electrum is a much more noob/user friendly wallet. This wallet offers a lightweight client, as it does not download the complete blockchain to your computer or device. Electrum works in a way that their servers perform all the heavy work so that you don't have to.

Electrum also offers much better options to restore your wallet when you forget a password or lose your computer/device. When setting up your Electrum wallet it will give you a "seed" which consists of a QR-code and a sentence of random words. I would strongly advice to physicly print this QR code along with the words in the correct order on to a real paper and store it somewhere safe.

This way you can always use this little paper to restore your Bitcoin wallet in case of emergency.

All of these nice funcions that Electrum has, have ofcourse, a downside. With Electrum you will have to trust the people behind Electrum. They will be holding on to your Bitcoin, if they screw up you could lose all your Bitcoin.

Pro's:
  • Easy to use / Noob friendly
  • Easy to restore when lost
  • Lightweight client
Con's:
  • You have to trust Electrum
  • Dependancy of Electrum servers


#3 Blockchain.info Mywallet


This is in my opinion by far the most easy to use wallet with the most restore options in case you lose your wallet. Just like Electrum this wallet will offer you a security seed upon setting up the wallet. Again I would strongly recommend to print this seed out on a paper and store in somewhere safe.

Other than that myWallet has alot of security options to prevent people from accesing your Bitcoin. It has the ability to setup a double password, SMS, Yubikey and other verification methods. It will also automaticly send you a back up of your wallet after you change someting, this can also sent to your dropbox, google drive etc.

In other words, you really need to be a complete retard to f*ck this wallet up and lose your Bitcoin.

Pro's:
  • Even a complete retard could not lose this wallet
  • Only iPhone compatible wallet out there
  • No software installation required
Con's:
  • You have to trust Blockchian.info with your coins
  • Dependancy on Blockchain.info servers

There are many more wallets out there, you can find out more here:

Even the best wallet cannot give you any protection from a malicious/infected computer with a keylogger. If you are using a computer that you are 100% sure of its safety I would always like to recommend to use the screenkeyboard in Windows to type in the password, this way you have some security against keyloggers.

Signing out for today.

What is Bitcoin ?

I would like to start this blog with an article about what Bitcoin is.
Readers might already be familiar with the basic principles of Bitcoin, but for the newbies I will be explaining the "What" in Bitcoin.

In later articles I will go into the "Why" and the "How" of Bitcoin. For anyone that is completely new to Bitcoin I will post the "official" What is Bitcoin video by the Bitcoin Foundation.


But  Bitcoin is much much more than just the Payment service described in the video. Let me explain:

Next to a very cheap, fast and honest payment system, Bitcoin is also a currency at itself, and right now Bitcoin can even be seen as a commodity. Why do I say right now ?

Right now, Bitcoin is mainly used by people to get money from A to B. A person needs to move say 100k USD, he will buy Bitcoins for 100K worth USD. This person will now travel to the other side of the globe, here he trades his Bitcoin back to local currency, free of transaction costs, taxes and other hassles that fiat currencies have. It is safe to state that Bitcoin can be seen as digital cash, cash as in anonymous money with no footprints that will trace back to the buyer/seller.

As Bitcoin reaches critical mass, people will not have to trade their Bitcoin back to local currency, for they can just spend their Bitcoin directly. At this point in time Bitcoin will shift from a commodity and a payment system into a real currency.

There are alot of other subjects of Bitcoin that I would like to address, but as this is just a What is Bitcoin article I will save this for future articles. The next articles I will try to explain some things about Bitcoin mining,different Bitcoin wallets, limited supply and the effect it has on inflation, future and target value's of Bitcoin and trading and investment oppertunities.
