These are called vanity addresses. They are made by randomly generating addresses until one is found by chance to have a prefix that you want.

2)why my btc address changes ?

For privacy and security reasons. It is recommended that you do not reuse addresses, so every time you want to get an address to give to someone, your wallet will give you a new address. Your old addresses will still work, just that your wallet knows it has already given you that one, so it gives you a new one. This helps preserve your privacy and makes it easier to keep track of your coins. It can also help protect your coins in the event that ECDSA is broken.

Bitcoin protocol does NOT allow addresses to be tied with names or any information. No information will be shown in the address.

However, if you are talking about this[1], the name can only be shown inside blockchain.info and nothing else. You won't be able to see ranochigo when you send Bitcoins to that address as stated before, unless you are using anything related to Blockchain.info. It is stored in the server, if they go down, the tags would all be gone. You can set it here[2].

2)why my btc address changes ?

Your Bitcoin address never change. If you go to the receive Bitcoin page of most wallets, your address shown would change after you receive Bitcoins to it. The only reason for it to change is to discourage address reuse. The previous address is likely still usable, at least for most wallets. You will still be able to send Bitcoins to it and have it displayed in your wallet just fine.

You can generate a custom address here (https://bitcoinvanitygen.com/). The site allows you to choose up to 6 characters for free. So you can generate an address that has your name (or at  least an abbrevation ) in it. The reason your address changes everytime is due to privacy concerns. Most online wallets give you a new receiving address each time you make a transaction. But you will still receive the bitcoin if you use an address more than once.

Yeah, that's vanity address. It's like bruteforcing and one would check millions of keys per second till they find the correct combination. The longer the prefix is, the harder it is to get.

Don't use the site the user above suggested, I vaguely remember that there were some reports of the server stealing the Bitcoins through the private keys generated by them. If you can't generate it yourself, you can opt for split key generation which is way safer. I can help you with it if you'd like, just PM me.

You should not use that website, they are known to have issues in the past where people have had their money stolen when they used vanity addresses generated on that site. Even if they are not scammers, you should never use a service where they generate a private key and give it to you to use; you never know whether they are holding on to that private key and can thus steal your money in the future. You should instead use local vanity address generation software like vanitygen: https://bitcointalk.org/index.php?topic=25804.0. Or you can use a service which uses split key vanity address generation. Split key generation keeps your private key private, the person generating the address only has part of the private key and they can't get the full private key.

If you use a web site like the one above, someone else does know your private key, perhaps more than one.  It is never a good idea to share it with anyone no matter how trustworthy they claim to be.
