QUESTION: Can you choose a specific address?

[btc4peace]

Does anyone know if it is possible to create an address for a crypto but you choose your own address?  I mean it would have to be an unused address of course.  Just curious.  Or, are address creations always random?

Of course... it always random. You can only choose the private key (with some wallets, you can do that).

I sit there when bored and click through 1000's of them to get address that end in English words.  This way I can quickly and easily spot check my address when transferring funds.  Would be cool if you had one that was a complete sentence or something.  I usually go for a 3 letter word at the end.  Best i have gotten after many attempts is LEGOS (5 letter word)

There are few services that could allow your requirement. But personally, I would prefer it as random as it could be due to security/anonymity and privacy reasons.

There you go. That's the perfect answer for your question. But it seems like you will need a lot of processing power to generate a wallet address of your preference. And the more personalized wallet address you wish to generate, the harder and time consuming it is.

For bitcoin its possible but for few first characters/letters.

This is for bitcoin.

OP if you are looking for bitcoin address, this is what you are looking for.
But for altcoins, I'm not sure if this will help you.
Vanitygen support for 70+ altcoins! +oclvanitygen and encrypt decrypt privkeys

The reason i asked is because there may be a serious security flaw if this is the case. 

Not trying to do anything with it, and will not mention the flaw.  Going to test on my own wallets and if i can "hack" myself then i am dumping those coins!

Vanity generators say they take longer when using more characters, ie finding an address with the word "cat" takes less time than finding one with "elephant".

What if I had a full address to search for?  Well of course if the address already exists on the chain then i could not generate the keys.

But, what if i could "trick" it into thinking it is a new address (and in my idea, it could) and I got a valid private key to that address.   Couldnt i just import the address with the private key then dump the wallet?

It may only work with certain altcoins.
