Why is my bitcoin address constantly changing?

No idea what you are getting at, but if you have your Bitcoin on an exchange they may often change the deposit address so consider downloading a wallet client to keep your Bitcoin safe.

To be more secure the address changes randomly and there is nothing to panic about it. This is just an advancement provided by the wallet service providers. Now user fear whether the address once got it changed has complications in receiving the bitcoins after days, which is always a NO.

I am pritty sure about that you are using mycelium wallet and if not then the problem is probably same. you will get a new address after each transaction as it helps to secure your privacy and it makes it impossible to track you. these short o wallets are called HD wallets (you can still use your old addresses for transactions) and its default in mycelium. if you want one fixed address you can goto add keys advance and generate yourself a new private key..that will be fixed or you can import your address from any other wallet using private key importing.

Most of wallets such as coinbase and blockchain change your address after every transaction. One of the reasons I know is your privacy. Because third-party cannot know your balance or your transactions history.
Note that you can reuse the previous addresses for your payments.

Most of the web exchanges like Coinbase and XAPO have feature of changing bitcoin address to ensure that unique addresses are being provided everytime doing a transaction. Other reason are for anonymity. But you can still used your previous addresses if you want.

There is an explanation about that. I suggest to look at your wallet's website and head to their Frequently Asked Questions (FAQ) section.

For the same reason that invoice numbers change.

A bitcoin address is something you give to someone so that they can send you an agreed payment.  As long as you keep track of who you gave the bitcoin address to, and what you gave it to them for, then you can identify who paid you, and what they paid you for.

If you re-use a bitcoin address (giving it to multiple people or for multiple payment purposes), then you don't have any way to identify who a payment is from or what it is paying for.

A bitcoin address is NOT an account number.  It is simply a payment tracking number.  If you are using it as an account number, then you are doing it wrong.

Additionally by using a new address for every payment that you receive, you increase your privacy and security a bit,

What is the name of the wallet that you use?
I have never faced with that problem on my Blockchain wallet. I also think that the wallet, that you use, makes it for safety of your founds. I don't see another reason. If everything is ok with your transactions it myst be just like I am saying.

To conserve your privacy. Although you can use the same bitcoin address as many times as you want it is never recommended to use the same address over and over again. This is done to keep your privacy safe.

Good point. By changing the unique bitcoin addresses linked to your bitcoin account, let's say an online wallet system, they prevent others from tracking ypur transactions.

I found answer one of blockchain support:

"Our wallet is built on an HD (or hierarchical deterministic) framework, which has a different method for address generation and management. Each public address your wallet generates stems from your wallet's xPub (or Extended Public Key).  Once your public address receives an incoming payment, a new address will automatically be generated and display when you click on receive.

If you use the same address each time you receive funds, it becomes easy for anyone to track your entire payment history. This method of address generation improves privacy by automatically presenting you with a new address when you’re expecting payment."

Hope it is will good for you.

It is quite common for your bitcoin address to change constantly if you are using an online wallet, I experienced that too in the past when I am using Coinbase, there is nothing to be worried about. I believe one of the reason for online wallets to have this function is due to privacy reason. By the way, you could still reuse your old bitcoin address to receive bitcoins into the wallet.

I thought that something went wrong. That I did not correctly enter the data. Thank you. Now everything is clear.

It is normal for most HD wallets. This is done for privacy reasons so it won't be easy for anyone to just track all your transaction histories. Nevertheless, using the old wallet address will not stop you from receiving your assets as it is already tied to your wallet.

The confusion is here: "my address". You don't have an address, you have a wallet, and the wallet generates addresses that are used to receive bitcoins.

If you don't like that then use another wallet which doesn't do that.

The address that I've created on day 1 when I was introduced to bitcoins is still the same address that I use today for all my btc actions.

I suppose you're using XAPO or Coinbase. You might consider switching to something like electrum or mycelium or blockchain.info

I observed in my blockchain wallet initially i got confused and then after reserch its nothing to care about . I always give my initial address got from Blockchain i kept it in notes always i send that address for recieving payment . Its just for the security purpose they change adderess. But in exchange wallet its always been same .

It would change if you do press the feature on receiving bitcoin. There are wallets that do have this kind of changing address for the sole purpose of privacy. Lets make an example on coinbase, I'm using it and I do have wallet address that I do create later on when I do make transactions on receiving bitcoin you can able to see another wallet address but still it would surely credit on your wallet if you do make transfers.

Blockchain.info also has the same features, but this shouldn't be a concern as your old address is still able to receive and functioning like it should. They are doing that so you'll have more security because more addresses makes its harder for you to be hacked, as far as I understood their explanation.

All you have to do is to choose the right bitcoin wallet is indeed one of the bitcoin wallet there is a frequent change of address so it makes us worry if we make a deposit into it, I also have experienced it but I do not wear the wallet anymore because the address of the wallet Which is always changing which of course makes worries btc we can enter or not into the wallet.

Majority of online wallets generate a new address for every transaction (i.e after the address receives money, they add a new one for future transactions). The old one is still usable in all the wallets I tried, but according to blockchain.info, they do that to maintain user privacy and to avoid being linked to a single address.

I'm confuse about this bitcoin wallet address that constantly changing!
I don't experience these thing sense I open my bitcoin wallet and other alt-coin wallet long time ago!

May be you should change your bitcoin wallet provider then if you experience this thing! to be sure that you don't loose all of your earnings.

That is just your wallet generating new addresses for each time, but the old addresses are always usable and even viewable if you are using Electrum which does this for each tx.

It's changing to protect your account that it should not be hack by some poor act by hacker in a globe network. Bitcoin is 100% secured network. Which is providing crypto currency in the name of bitcoin which is 100% secured therefore your address changing constantly. To protect your address 24 hours thank you.

Good explanation about this change. I also wondered why online wallets changes the adresses and I got my answer. I wish parity eth wallet to do the same as well like bitcoin.

Ethereum works differently.

We need way more information than that. Are you using an online exchange? Or an online wallet? Are you using a desktop wallet that has a changing address? There's a lot of different things that need to be taken into account and you can't just ask why something is changing without explaining it more.

If it is an online wallet, then most wallets change addresses to help obscure the owner of a wallet. You will always receive your Bitcoin either way, though. If it is an offline wallet, then chances are it has a similar function but it is simply changing the public address and still lumping all your Bitcoin together.

Bitcoin address consequently changing it's obviously positive for help to secure.

They are trying to protect you from others spying on your bitcoin transactions. If they used the same address all your purchase history would be naked (http://realnakedgirls.net) for everybody to see. Besides, we don't have to worry about the world running out of bitcoin addresses.

I don't have any idea why is it happen but one thing I know that is because bitcoin is not stable and it will change from time to time it will increase or decrease. We must be always positive that bitcoin will increase.

We should have more control over changes to public addresses and i bet lots of money goes missing because of this

if i want to change my email address every day for "Security" then that's my decision and maybe i want to scan the block chain
myself for all my spending and i have better things to do than to type in 50 transaction ID's

This is for your own security (said by a Blockchain care assistant)
The thing is your wallet contains more Bitcoin addresses that you can use again and again, but for your protection Blockchain technology constantly changing your bitcoin address for your own security

You are focusing too much on the addresses. Let the wallet manage the addresses. There is no need for you to get involved. My wallet has generated hundreds of addresses. I have never needed to keep track of them. My wallet lists every transaction I have ever made.

Either way, you can reuse addresses if you want. Get an address from your wallet, and print the QR code on a piece of paper and laminate it. Now you have your one address.

It changing constantly so that you can have more security because if your bitcoin address given to someone they can request payment thats why it changes constantly after a transaction is done.

Yes surely it is just for your own benefit and your own security. I have bitcoin and will like if I will have proper safety for it. Now in several wallets bitcoin address use to change and will give you your own key word for your own bitcoin new address. It is fine to have your own password and your own benefit related to bitcoin wallet and safe key address.

Could you specific in which environment is it changing? Local app wallet? Web browser? There are trojans/virues that changes addresses just after you paste them in input fields to stole your coins, so in that case, the fact that is changing is bad!
