&lt;hr /&gt;
&lt;div&gt;An account can effortlessly be created using an [[eWallet]] service. eWallet services provide an online wallet to hold your bitcoins.&lt;br /&gt;
&lt;br /&gt;
This guide covers installing Bitcoin without needing a third party wallet service.&lt;br /&gt;
&lt;br /&gt;
== For Windows computers ==&lt;br /&gt;
&lt;br /&gt;
=== Installation ===&lt;br /&gt;
[http://sourceforge.net/projects/bitcoin/ Download] and install Bitcoin.&lt;br /&gt;
&lt;br /&gt;
[[File:Install fin.png|frame|none|Complete installation wizard]]&lt;br /&gt;
&lt;br /&gt;
=== Initialization ===&lt;br /&gt;
&lt;br /&gt;
The first time you run Bitcoin, it needs to download all the blocks to setup. You already have your bitcoin address at this point, but you won&#039;t see any transactions before the initialisation is complete (it can take from half to a few hours).&lt;br /&gt;
&lt;br /&gt;
[[File:First time run fin.png|frame|none|Bitcoin is initialising by establishing a connection to other clients and downloading the blocks.]]&lt;br /&gt;
&lt;br /&gt;
[[File:Bitcoin all blocks fin.png|frame|none|Completed download of block-chain.]]&lt;br /&gt;
&lt;br /&gt;
Your address (you can have as many as you want) is at the top. Below is your balance which will be zero. The list below shows your transactions.&lt;br /&gt;
&lt;br /&gt;
== For Mac computers ==&lt;br /&gt;
&lt;br /&gt;
Download the [http://sourceforge.net/projects/bitcoin/files/Bitcoin/bitcoin-0.3.19/bitcoin-0.3.19-macosx.zip/download OS X version] of Bitcoin and expand the archive.&lt;br /&gt;
&lt;br /&gt;
[[File:BcOSX.png|thumb|none|Contents of the Bitcoin archive after expansion]]&lt;br /&gt;
&lt;br /&gt;
Drag the Bitcoin icon to the desired install location, and double-click or Cmd-O (⌘O) to run the application. The Bitcoin window will open and connections will start up in minutes. The blocks will begin downloading. Your address and balance are at the top of the window. Click &amp;quot;Copy to Clipboard&amp;quot; to copy your address. Transactions are displayed in the main window.&lt;br /&gt;
&lt;br /&gt;
[[File:BcOSXrunning.png|thumb|none|Main window]]&lt;br /&gt;
&lt;br /&gt;
As Bitcoin currently does not support hiding with Cmd-H (⌘H), it is recommended that users tick the &amp;quot;Minimize on close&amp;quot; option in the Preferences menu to prevent accidental program exits.&lt;br /&gt;
&lt;br /&gt;
[[File:BcOSXPreferences.png|thumb|none|Preferences window on OS X]]&lt;br /&gt;
&lt;br /&gt;
== Getting my first coins ==&lt;br /&gt;
&lt;br /&gt;
The  [[Bitcoin Faucet]] [https://freebitcoins.appspot.com/ website] currently hands out 0.02 BTC to new bitcoin users. Fill in the form with your bitcoin address.  When you wish to add more, view [[Buying bitcoins]].&lt;br /&gt;
&lt;br /&gt;
[[File:Get some btc.png|frame|none|Getting free coins from the Faucet]]&lt;br /&gt;
&lt;br /&gt;
A new entry should appear in Bitcoin. The network hasn&#039;t yet confirmed it, but you know it&#039;s being processed. After about one hour it should get 6 confirmations. You are able to spend the coins when there is only one confirmation.&lt;br /&gt;
&lt;br /&gt;
The confirmation counter (like the block counter) will increase by one roughly every 10 minutes. Six confirmations are considered as 100% sure a transfer has been processed.&lt;br /&gt;
&lt;br /&gt;

* Create an account on witcoin and post something (cost 0.01 BTC): &amp;lt;br /&amp;gt;http://www.witcoin.com  (click &amp;quot;get wit it&amp;quot; to create an account)&amp;lt;br /&amp;gt;If your post is any good, you can earn when it gets replies and votes.&lt;br /&gt;
* Give a tip to a deserving artist, writer, etc. on YouTipIt.org.&amp;lt;br /&amp;gt;For instance, this video creation is worth 0.05 BTC, no?:&amp;lt;br /&amp;gt; http://www.youtipit.org/t/2652&lt;br /&gt;

* Give to any of the charities on Bitcoin Trade page:&amp;lt;br /&amp;gt; http://en.bitcoin.it/wiki/Trade#Donation-accepting_organizations_and_projects&lt;br /&gt;
&lt;br /&gt;
== Points to remember ==&lt;br /&gt;
&lt;br /&gt;
* You don&#039;t need to be online to receive BTC.&lt;br /&gt;
* You can create as many new addresses as you like. Using a different address each time helps keep you [[Anonymity|anonymous]].&lt;br /&gt;
* You can be [[Anonymity|anonymous]] with adequate precautions.&lt;br /&gt;
* You cannot send BTC to an invalid address. Typos are not a worry as the payment will refuse to send.&lt;br /&gt;
* The [[Wallet|wallet]] file holds the keys that allow spending and thus the computer should be [[Securing_your_wallet|protected]] from the risk of loss and theft.&lt;br /&gt;
* Leaving Bitcoin open improves connectivity for the network and ensures that you don&#039;t fall behind on the block chain. Also see [[FAQ#Do_I_need_to_configure_my_firewall_to_run_bitcoin?|the FAQ about port forwarding]]&lt;br /&gt;
&lt;br /&gt;
Proceed to the [[Introduction|introduction]]&lt;br /&gt;
&lt;br /&gt;
== Technical ==&lt;br /&gt;
=== Block chain ===&lt;br /&gt;
The [[block chain]] is a neverending story of every transaction throughout the network from day 1 (genesis). The first time you run Bitcoin, it is downloaded and verified on your computer. Every new transaction is added to the end of this chain and verified by the network to be valid.&lt;br /&gt;
&lt;br /&gt;
=== Addresses ===&lt;br /&gt;
Whenever you send a coin, you are actually sending a cryptographically signed message, associating your coin with the recipient&#039;s address. This effectively transfers ownership to to the recipient. Once they own the coin, they are free to transfer it to another person.&lt;br /&gt;
&lt;br /&gt;
A wallet is a collection of addresses. You can create as many new addresses as you wish; having more addresses makes you more anonymous, because then people cannot see how much BTC you received. Your wallet contains the secret keys used for spending that money, and must be [[Securing your wallet|backed-up regularly]]. If you lose the wallet then you no longer possess the money.&lt;br /&gt;
&lt;br /&gt;
=== Generating ===&lt;br /&gt;
New coins are minted through generating hashes. These generators are rewarded with a small fee for the computationally intensive task of incorporating your transactions into the block-chain.  This fee halves each time 210000 blocks are added to the block chain, or approximately every 4 years.  The fee will keep halving until it effectively reaches zero, at which point 21 million coins will be in circulation.&lt;br /&gt;

&lt;hr /&gt;
&lt;div&gt;A &#039;&#039;&#039;mining rig&#039;&#039;&#039; is a computer system used for [[How_bitcoin_works#Bitcoin_mining|mining bitcoins]].  The rig might be a dedicated miner where it was procured, built and operated specifically for mining or it could otherwise be a computer that fills other needs, such as performing as a gaming system, and is used to mine only on a part-time basis.&lt;br /&gt;
&lt;br /&gt;
==Tips==&lt;br /&gt;
&lt;br /&gt;
* Motherboards with on-board graphics (also referred to as integrated graphics) often are either problematic or unusable when more than one GPU card is installed.  Choose a motherboard with no on-board graphics.&lt;br /&gt;
* The following component lists might be used to help in building a new rig.  To minimize shipping costs, components from the same supplier were preferred over compenents from the least expensive source.&lt;br /&gt;
&lt;br /&gt;

		<summary type="html">&lt;p&gt;Paperfree: Replaced the single 6990 build with a 5850x3 build for more Mhash/s at less cost.  Also made some other minor changes for clarification.&lt;/p&gt;
&lt;hr /&gt;
&lt;div&gt;A &#039;&#039;&#039;mining rig&#039;&#039;&#039; is a computer system used for [[How_bitcoin_works#Bitcoin_mining|mining bitcoins]].  The rig might be a dedicated miner where it was procured, built and operated specifically for mining or it could otherwise be a computer that fills other needs, such as performing as a gaming system, and is used to mine only on a part-time basis.&lt;br /&gt;
&lt;br /&gt;
==Tips==&lt;br /&gt;
&lt;br /&gt;
* Motherboards with on-board graphics (also referred to as integrated graphics) often are either problematic or unusable when more than one GPU card is installed.  Choose a motherboard with no on-board graphics.&lt;br /&gt;
* The following component lists might be used to help in building a new rig.  To minimize shipping costs, components from the same supplier were preferred over compenents from the least expensive source.&lt;br /&gt;

&lt;hr /&gt;
&lt;div&gt;A &#039;&#039;&#039;mining rig&#039;&#039;&#039; is a computer system used for [[How_bitcoin_works#Bitcoin_mining|mining bitcoins]].  The rig might be a dedicated miner where it was procured, built and operated specifically for mining or it could otherwise be a computer that fills other needs, such as performing as a gaming system, and is used to mine only on a part-time basis.&lt;br /&gt;
&lt;br /&gt;
==Tips==&lt;br /&gt;
&lt;br /&gt;
* Motherboards with on-board graphics (also referred to as integrated graphics) often are either problematic or unusable when more than one GPU card is installed.  Choose a motherboard with no on-board graphics.&lt;br /&gt;
* The following component list might be used to help in building a new rig.  To minimize shipping costs, components from the same supplier were preferred over compenents from the least expensive source.&lt;br /&gt;

		<summary type="html">&lt;p&gt;Paperfree: Changed dedicated miner CPU&amp;#039;s to AMD Sempron 140&amp;#039;s since they cost less use less power&lt;/p&gt;
&lt;hr /&gt;
&lt;div&gt;A &#039;&#039;&#039;mining rig&#039;&#039;&#039; is a computer system used for [[How_bitcoin_works#Bitcoin_mining|mining bitcoins]].  The rig might be a dedicated miner where it was procured, built and operated specifically for mining or it could otherwise be a computer that fills other needs, such as performing as a gaming system, and is used to mine only on a part-time basis.&lt;br /&gt;
&lt;br /&gt;
==Tips==&lt;br /&gt;
&lt;br /&gt;
* Motherboards with on-board graphics (also referred to as integrated graphics) often are either problematic or unusable when more than one GPU card is installed.  Choose a motherboard with no on-board graphics.&lt;br /&gt;
* The following component list might be used to help in building a new rig.  To minimize shipping costs, components from the same supplier were preferred over compenents from the least expensive source.&lt;br /&gt;

&lt;div&gt;Love the multi-tiered structure.  One question... 5850&#039;s are mentioned a lot on the forums.  Combining two of them together seems to get you to the 700 M/hash range, and costs under $470 ($185-$235 each) vs $734 for the 6990.  But I&#039;m not very experienced and haven&#039;t done this myself yet, just been looking into it.  Is there a reason to opt for the 6990? --[[User:Paperfree|Paperfree]] 04:05, 18 May 2011 (GMT)&lt;/div&gt;</summary>
