Bitcoin Forum

I am interested to know if people keep addresses or use new ones all the time.

If you use new ones all the time, if you could explain why that would be great.
and do you identify yourself with your bitcoin address?

I have one adress who I had since I begin and for the other I change every 1 month.

Vote if you will please, I am doing a some research to see if a project is viable or not.

Ok excuse me I voted.

I use different ones, because it helps me keep track of where my BTC is going in and out, and because I get tired of look at the same letters all the time.

Ight, would you be opposed to having a main one just so people could identify you like a pgp key? you can always load private keys to your main wallet. Please vote as well thanks!

I've had it for a little while. I don't like changing it for no reason. Voted!

Awesome and thanks!

Use new one every few months.

any reason why? If its DM's or whatever I understand and you do not have to say

Voted. 1-6 months. I think like 4 months. This reminds me of the Hotmail email address thread I saw. Many people said that they knew they should change their email address, but they'd had it for forever and it was associated with so many different accounts/sites, and it would be a huge hassle to switch. The sad thing is that I've had a hotmail email address a long time too.  :(

Anyways, I've had one (BTC addr.) for about 4-5 months, the same address I had when I started with Bitcoin just back in February. But I've learned a lot since then and jumped right in to the Bitcoin culture. I now own a Bitcoin site that has my own faucet, super stoked on that. I have another address however that I use to keep track of a lot of different things. But the original is 'Old Faithful' lol.

Bitcoin works with an unprecedented level of transparency that most people are not used to dealing with. All Bitcoin transactions are public, traceable, and permanently stored in the Bitcoin network. Bitcoin addresses are the only information used to define where bitcoins are allocated and where they are sent. These addresses are created privately by each user's wallets. However, once addresses are used, they become tainted by the history of all transactions they are involved with. Anyone can see the balance and all transactions of any address.

I use a new address for every single transaction

I have my offline wallets (half-a dozen of them) for more than 1.5 years now. I see no need to change them, as they have been never exposed online. However, I change my online wallets once every three months or so.

Got one for cold storage of almost all of my BTC. It's a few months old. There are other addresses for smaller amounts that are older and some are newer.

I started with bitcoin about eight months ago. I still use the same and only btc address. Is it better to change addresses or doesn't it mather?

As long as you don't expose your private key, you're perfectly safe.

Using the same one from 6 months now, maybe it's time to change it now.  ;)

My main paper wallet is 8 months old and all my other wallets mostly under 1 month.

Thank you all for all the responses its is helping greatly in my research.

I have used my current one for about 4 months. It is only for sig campaigns. I have another one for mining revenue which is over 1 year old. I use a different address for different purposes and seldom change it. I will use a new one when an address takes too long to load all transactions in my blockchain wallet.

You may not realize it but you have just opened a huge can of worms.

Address reuse is one of the most important issues in the entire Bitcoin ecosystem.

Address reuse is at the heart of the financial privacy, taint analysis, fungibility and coin black/gray/red/white listing issues.

This is one of my pet concerns as you can tell by my signature below this post.

Ideally address reuse should be forbidden.  It is forbidden in some alt coins and they are better off because of that.  But address reuse has become entrenched in Bitcoin.

For a lively debate of the issues at hand see how people responded when Luke-Jr (the Eligius mining pool) suggested we just gently economically try to persuade people to stop doing it (for the good of the entire Bitcoin ecosystem) read this entire thread:

If you follow my personal responses in the thread you will find me very hostile to the idea until I realized the importance of this issue.  Now I am 100% against address reuse, vanity addresses and other things that undermine the long term survival of Bitcoin.

If you are interested in these very important issues please read the entire thread.  However the most important post in the thread is this one post by Greg Maxwell:

That one post took me from this:


to this:

So Burt would you be opposed to keeping 1 wallet so the community could be able to identify you? for reference? It would act kinda like a PGP

I have my wallet somewhere from 5 to 10 months and I didn't change It , what is the point of changing the wallets address each time? I guess for security but That Is only If you have a huge pile of bitcoins , I mean like 500-1000+. But If you have a lot of bitcoins you just keep them in separate wallets and no need to change them still? Can't tell much bout It because I just use one or two wallets.

Do you mean wallet (collection of Bitcoin addresses) or one Bitcoin address?

Would this wallet/address be used for actual transactions?

I have had my original wallet, well since the begining. it is what i use for Wot. I don't use it anymore (except for WoT) but i have gone thourh heaaaps now.

backing up heaps :)

Before someone asks "How does my address reuse, because I really don't care about my financial privacy, affect those that do care about it?"

Just one wallet for the sole purpose of identity verification. I hate to say this.. but kinda like a social security number.  
Like lets say

Bobblank would like to take out a loan with lendy mclenderson.

Lendy can go check out bobs address to verify he is who he says he is,

this is mainly aimed at lending, and securities verification and to stop this horrible amount of scamming. I am gathering data to kinda build a credit agency type deal.

This is part of my research, if lenders and investors required people to have some sort of verification we could cut this scam crap down by more then half I feel and reshape the image of bitcoin "being full of scams".

Pretty much it would work like other credit agency's but your address would be your identifying number.
Lenders and investors require a client to be registered with us. We contact the client as for a address they would like to be identified.
We then as them, First and last name and state they are from. Pull a background check ask some verification question only they would know. WE WOULD NOT hold any information besides the persons name, btc forum name and BTCaddy.
When a lender/investor logs into our system they could either type in a BTCaddy or persons name.
It would return a database read out something like this

Client log in "they See"
Bitcoin address verfied?
User Name
Risk level?
Phone Number verified? Yes or no?
Residence Verfied? Yes or No?
Cross checked? Yes or No?
Loans, Dates, Amounts. Accounts closed or open.
Credit Score?  1-1000
Late Payments? The amount of late pays
Collections? Amount and Person owed
Loan Modifications? Modifications to Loans and Terms.
---------------------------------------------------------------------
Risk Level  ********* need to figure out **********
Credit Score **********need to figure out *********

OK, lets say I have a wallet with let's say 100 Bitcoin address (100 private keys).  What next?  Do I register these 100 public keys or 100 Bitcoin addresses with you (some authority)?

Is that the basic idea?

No just one address you would be willing to use to identify with.

OK.  To avoid confusion in the future please use the term "wallet" as a collection of "(Bitcoin) addresses".

So this address is used just to identify a person.  There are no transactions using this address.  Totally fine.

They can use the address as their ID number, sign messages with the private key to prove their ID and they do NOT send or receive BTC using this address.  Totally fine.

Yup thats exactly how it would work, only verification and loans.  Be like a bitcurity number or something like that lol

Technically totally possible.

On the business side you have (at least) two issues:  fake IDs and your liability exposure.

Let me know if I can help you out with any technical matters.

I've had my static Bitcoin address for about four months, before that I kept my coins on Coinbase because that seemed like the safest place to leave them while I learnt about how to properly secure them on my own. In retrospective, blockchain.info would have been better, since it does not keep the user's private keys.

Fake I.D. will not pass my background check, I will not even require a physical copy of a I.D. in most cases.
I ask them First last and middle state of residence or previous state if it has been less then 2 years.

I pull a background check and ask them question only they would know ex. have you ever been convicted of a crime if so what?
Do you have any previous addresses?
Do you still have this email? then I will send them a email with a random code then ask for them to repeat it back.
I have many more ways of checking but I do not want to give them all away.
Call them on the background check numbers listed.

Seems like a reasonable start.  Good luck!

I still new on bitcoin, not longer than 2 month ago...

Hope I can get some fortune here. For now, I only depend on cloud mining service.

I did collecting from faucets,, but it took too long for me, so I stop it.
