Could someone help me with how I could make a "vanity address"? I heard you can have a computer generate it with the letters you want yourself the address to have. But don't really understand how that would be possible to do. And how you would get your private key?

Sorry I'm sort of new here.

They way vanity addresses are generated is to run a program that generates random private keys and then calculates the addresses from the private keys.  If repeats this process as fast as it can comparing each address to what you want it to look like until it finds what you're looking for.

There are a few programs available to do this.  As devthedev said, it would help to know what operating system you are using.

The more letters or numbers that you want to match, the longer it will take until the program finds a matching address.

If you just want to match the first letter of the address (after the 1), you will find a match on average in 1 out of every 58 addresses that you generate.

If you want to match the first two letters, you'll find a match on average 1 out of every 3400 addresses that you generate.

If you want to match the first three letters, you'll find a match on average 1 out of every 195000 addresses that you generate.

If you want to match the first four letters, you'll find a match on average 1 out of every 11.3 million addresses that you generate.

If you want to match the first five letters, you'll find a match on average 1 out of every 660 million addresses that you generate.

If you want to match the first five letters, you'll find a match on average 1 out of every 38 billion addresses that you generate.

As you can see, it quickly gets very difficult (and time consuming) to find an address that matches many letters.

Thanks for the explanation. Is this a program that everyone could learn how to use and maybe run on their own PC? As asked above I'm using Windows 7.

This does sound complicated. Can I use my gpu to do this like with mining?

What could I invest into with $10 or 0.0154btc? I earned this from Primedice.com, if anyone is curious.

Throw it into cold storage and wait for us to go to 10k/BTC ;D. And, do not gamble, you'll end up losing it all...

You definitely can! It's not too complex at all. Grab the binary here, unzip it and put it on your desktop. Let me know when you get to that point.

For ease it's here: https://github.com/downloads/samr7/vanitygen/vanitygen-0.22-win.zip

Extract to where ever you want.
Go to that folder, Shift + right-click (not on a file), choose open command line here.
In command line type:
vanitygen64.exe -o names.txt 1name
That's it.

Breaking that down that down.
vanitygen64.exe runs the program with following settings.
-o (lowercase O) means save to file with following name. (makes one if not found)
names.txt is the file to save to call it whatever you want.
1name is the name to search for, choose whatever you want but start with "1"
The shorter the name the faster the result.

We've answered 15 questions in this thread so far! 35 more and we'll be giving away 1 Wood Wallet and 1GH/s on CEX.io!
Post any Bitcoin related question you have to get us closer! Whether it's about the Bitcoin Protocol, Mining, Legalities, Wallets, etc. we'll answer every question!

[DannyHamilton]

We've answered 7 questions in this thread so far!

EDIT: For every 50 questions asked I'll be giving away a free Woodwallet to a random user who's asked a question or helped others in the thread!

Lets count questions asked:

1.

When the difficulty changes how is it set?

2.

What is the difference between nodes and miners?

3.

What is a woodwallet?

4.

Are you new to the Bitcoin community?

5.

I'm using multibit and I want the Public Key (It's different than address) of my address, how do I get it?

6.

what do you plan using your public key for?

7.

Is there woodcoin since you have wood wallet?

8.

What does the the block header look like before and after hashing?

9.

Could someone help me with how I could make a "vanity address"? . . . And how you would get your private key?

10.

What operating system are you using?

11.

But, isn't this a waste of generating numbers? . . . won't that speed up the possible duplication of numbers in some future life time? Or would it not really matter because all but one of those numbers, the desired vanity address, ever be used?

12.

Could you recommend me begginer guides for mining, mainly about buying hardware, at what point the investment is worth it, which hardware to buy, etc

13.

What could I invest into with $10 or 0.0154btc?

14.

Can I use my gpu to do this like with mining?

This last one wasn't phrased in the form of a question, but clearly the question "What am I missing?" is implied:

15.

I've tried hashing that original block header but can't seem to get the corresponding hash that's recorded. I must be missing something.

Should i invest in couple of GPUs to try mining some alt coins or just stick to BTC trading? Is the risk worth the money? It is not a simple question, but keep asking and asking about this and i am getting so much different answer and i cannot go to the end.
Thank you!

BTC trading is extremely risky. It's essentially gambling, there's no sure fire way of predicting the markets. Investments in GPU's are risky too but probably the better of the two. You'll likely ROI in a few months if you mine with IPOMiner or a pool that always mines the most profitable coin.

I did this and it's now running at a speed of 1.21 Mkey/s, it should be finished in 3150 years... I noticed that it's mostly taking all of my CPU memory though, so it's not working with my gpu's?

If you have a Nvidia card, use the oclvanitygen.exe file inside the same folder, instead of the vanitygen.exe

I think Oclvanitygen may actually support AMD cards now. Give it a shot.

After I ran the oclvanitygen.exe with a test address it came up this:

Available OpenCL platforms:

0: [Advanced Micro Devices, Inc.] AMD Accelerated Parallel Processing
  0: [Advanced Micro Devices, Inc.] Hawaii
  1: [Advanced Micro Devices, Inc.] Hawaii
  3: [Advanced Micro Devices, Inc.] Hawaii
  4: [GenuineIntel] Intel<R> Core <TM> i5-4570 CPU @ 3.20GHz

But I don't know how to add the AMD gpu so that it will start working with it. What should I write in the command line for it to do it with the gpu?

1WTFisThis

With 9 characters (WTFisThis) after the 1, you'll find a matching address on average 1 out of every 7,428,000,000,000,000 addresses that you generate.  Of course you could get lucky and generate a matching address in your next attempt, but you could also get unlucky and generate 15,000,000,000,000,000 addresses before you find a single matching address.

Good luck!

You specify the device, using -d (device number).
For example, you should use oclvanitygen.exe -d 0 1WTFisThis. If it doesn't worked with all cards specified at the same time, run multiple instances with the different devices.
