There are approximately 120,000,000,000,000,000,000,000,000,000,000,000,000,000,000 possible addresses that start with 1bitco (that's 1.2 X 10⁴⁴).

There are approximately 80,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 possible addresses that do NOT start with 1bitco (that's 8 X 10⁵²).

So, for every address that you find that starts with 1bitco, you need to search through on average approximately 666,666,667 addresses.

Able to do the maths for "ojm" ?

how do I use it in my wallet?

(Bitcoin-QT)

Use the command: importprivkey (private key here)
Make sure to find one services that allows you to generate split vanity key. If no, the security will be 0 since the server knows your private key.

I'm interested in this too, can you find a website that provides that?
I'm new, I can't tell how secure is which website

I have used https://vanitypool.appspot.com/ they offer split key generation and https protection. However, their fees is a bit too high.

If you are unsure of the security/source i would suggest using it for fun but not as main wallet.   Might even split coins between multiple wallets.

Personally I would generate it myself.  But there are some sites that are known as reputable.

Is a vanity address hard to make?

Around 58x harder for each letter you want fix. So yes, they start to become hard pretty quickly.

58 valid character for the other spots

27 characters: (21)^58 (4*10^27) possible
28 characters: (22)^58(7*10^77) possible

Do I have my math confused?  (It's been known to happen from time to time).

Shouldn't it be 58²¹ and 58²²  (not 21⁵⁸ and 22⁵⁸)?

Then again, you do have a PRIMEDICE ad in your sig, and I've generally found that 99% of the people who have such signatures don't have any idea what they are talking about and are just spouting nonsense to get their post count up so they can collect more for the advertisement.

I'll just click "ignore" on your ID until I see some reason to do otherwise.

Its too easy point others errors when you just throw numbers from the thin air, giving no clue where they came from, so no one has a chance to verify if they are correct or at least make any sense at all.  Keep your good job, mister "I ignore others because I'm superior and the signature program dudes are a bunch of dumb people"
