bitcoin address question

[pedrog]

You can use an address as many times as you want, you can use bitcoin your entire life everyday and use only one address, but if you want your finances private you should change addresses often.

[ChuckBuck]

You can reuse the same BTC address as many times as you wish, I do it for several I own.  It's convenient.

The only reason you don't use only 1 is then a random person can just look up that address on Blockchain.info and see your remaining wallet balance.  If you juggle several wallet addresses instead of just 1, it shouldn't be a problem though.

Lastly and most importantly...any would be hacker/attacker would need to access your private keys, so if you secure these correctly, then nothing to worry.

better to use different address everytime for anonymity purpose, and to split your income(security reason)

but for some amount you can just use one address(your wallet will remain with the same size for a longer time, so you don't need to backup it often)

[Gisado]

You are encouraged to use an address only once, but nothing prohibits from using it several times.

An important difference, however, is that each address should only be used for a single transaction.

It recommended you to only use an bitcoin address for a single transaction to keep privacy & separate your bitcoin so you can manage your bitcoin easier.
But, you can use it multiple times if you want to

Some wallet like electrum & bitcoin wallet(android) are doing this
So, it's up to you now

Why is it important to only use it once to keep privacy?  On this forum tons of people have their address posted everywhere. Can you elaborate a little bit of why that would keep your privacy?

So how can I change my address in the wallet application? What happens to my previous address if I change after receiving a transaction?

You just have to click a button to create a new address. You all previous addresses are kept intact in your wallet program, so they're not lost. Any future Bitcoins you receive to your 'old' address are received just fine.

Is it possible for a wallet application to hold several addresses?

All wallet programs can hold several hundred of addresses, or more.

From a privacy perspective it makes sense to only use an address one time. From a security point of view, the longer you use a wallet the more prone you are due to human error to make that address vulnerable.

It depends on your computer. If you have a low-end CPU and low RAM, your wallet will be very slow if you have several addresses.

also on in lightweight wallets like Electrum for example, the more addresses and the more transactions you have, the slower the application gets.

Hi all,

There is a very simple question in my head about Bitcoin. I will be glad if someone can answer this.

Its about the Bitcoin address. It is stated that :

A Bitcoin address is similar to a physical address or an email. It is the only information you need to provide for someone to pay you with Bitcoin. An important difference, however, is that each address should only be used for a single transaction.

If each address can only be used for a single transaction how does one can receive more than one payments to his address.

Lets say I have a blog and I want to receive bitcoin donations to the address that I specified. Do I have to update the 30character code everytime that I receive a payment?

How does this work? Can somebody please explain.

Cheers

Bitcoin addresses are disposable, but You can use them forever if You want.

If you are using a paperwallet, remember that if you spend money from that address, I will have a lower security, because It won't be 100% offline.

If you are using a paperwallet, remember that if you spend money from that address, I will loose a bit of security.

All addresses are secured by SHA256, RIPEMD-160 and ECDSA, once you make the first transaction, you broadcast your public key which leaves you with ECDSA to secure your wallet. True that quantum computer could break ECDSA but it wouldn't be the first target. If you look at some wallets for example onchain dice, they always reuse address and never get hacked. The other security concern is weak RNG which could be exploited once you make a transaction.

That's all a wallet is, a collection of addresses.  Contrary to popular misconception, no coin is stored in the wallet.   All that's there are addresses.
