Topic: How many bitcoin address you have right now? why you have more than one? - page 9. (Read 8021 times)

I probably have atleast 20+ addys that I could receive BTC at.

I create new address of almost every new transaction. I think this is good practice to increase security. I do not care too much about number of address I have. This is task for my wallets I am using.

I have 3 address, but I only use one main, have many addresses to me is a bother.
2 other address only for the purposes of others.

In terms of security, both of them generate the private key without additional benefits to the security, only to the convenience of backing up the seed once and only. If someone has access to your seed, you would get all your coins hacked. With Bitcoin Core and other non HD wallets, they can't possibly get the whole list of address the user is using if they get an older backup.

Currently, the main use is for privacy and labeling. There is no risk of compromising the private key even if it has been used many times, till quantum computing comes out. Just look at satoshidice. As long as the RNG is not weak when generating transaction or private key. Exchange use different address to credit the correct account.

I have a different address for almost every transaction. I just use it to keep track of what i receive and what I send out. It is just for record keeping and simplicity, nothing more, nothing less. 

I think I only have a total of 9 addresses to my name, and most of them are empty if I remember correctly.

I have more than one as a means of dividing up large amounts of coins I used to have, but I don't particularly have large stores behind me right now, so I leave my remaining $.70 in a single account.

I want to try out one of my paper wallets, but that can wait.

I think, I must have over 150 addresses to date... I create a new address for every new service I use and I test all
wallets online, with a unique address. How can you evaluate a service or a wallet provider, if you have not tried all of
them. I also created 100's of paper wallets and then destroyed the computer it was created on.

I also use some honey pot addresses, to trigger traps on my desktops. {unprotected addresses with small amounts of coins}  

I have a lot of address especially the one i used back in 2012
For now i have about in total 40-ish
And from that many i only using 3 address
I forogt the password for the rest of the address

i have 3 address so far, im not sure why need alot of address,. had 3 but only use 1 of it 
but how to create cold wallet or hot wallet? and how that work actually

I currently hold BTC in 8 addresses.  I've probably used about 500.

HD Wallets are more secure in the way they generate the next address, and the next. It solve the problem of Hierarchical vs Deterministic method of seed and sequence. As long as you keep the master key, you can regenerate all the addresses after that so losing your wallet.dat is not a problem, like it is with non HD wallets.

It also has other useful to negligible benefits.

I like the fact that it helps making the transactions you do no related to one another. I appreciate the fact some exchanges has integrated this into automatically changing the receiving address as well.

This also help contribute to security.

HD wallets aren't more secure than regular wallets. They do prevent losses by making wallets do one time backup but if someone gets the key, all your addresses generated from that will be compromised. Wallets like Bitcoin Core only pregenerate 100 address so even if someone gets the old backup with your 100 used key, they can't do much.

Thousands? And thats what everyone should have. At least if securing your BTC is your priority.

Some people like to have one receiving address, but HD wallets are much more secure and there's not really a reason to not use one different address for every receiving transactions.

many addresses

I had around 11.

I use to run a small website where I did tips on getting started with bitcoin; "walkthroughs", BTC giveaways, links to faucets, and many other things. After that got going I found this site where I started doing daily raffles and TwitterGames. Gave away probably around BTC12 in BTC0.1 and BTC0.01 increments with some larger prizes occasionally. Some of that was from support from this great community by means of donations which became necessary after the raffles and games got larger. I needed those multiple address to keep track of various "accounts" for the site and the games I did on here; donations in, prizes out, main wallet, cold storage, and some wallets for other ventures. It was great and I met some really awesome people who wouldn't have been able to get into bitcoin without the small (then small) raffles and information. I had to stop doing the site when life got in the way; I moved, then school, a job, a girlfriend etc. It was so cool though that people on here donated/helped out to keep the raffles going and get newbies up to speed. Unbelievably good times. This forum does some real good for the community. I want to bring my small part of it back, albeit in much smaller amounts now that BTC is worth way more than $45 a coin. I'm not able to do this right now. Maybe after I sell a few bitcoin related things I'll be able to reach that goal.

Anyway, thats my story, and if tl;dr I needed multiple addresses for organization purposes.

Lots lost track of them down the line but using 1 steadily

I have control of more than ten addresses. Back before I use Mycelium as my wallet I used MultiBit. The software tell us to create multiple addresses to receive money from different people. So I created multiple addresses to receive money from different faucets. I quit Bitcoin after knowing faucets will not make me 1 USD easily. Even though I quit, I did not uninstall MultiBit.

When I came back in October last year, I have an Android phone. So I checked Bitcoin.org for some Android based wallet. I am fond of the design Mycelium have. So I uses it. I have only a few wallets in my Mycelium software. One being my old address and another one being my vanity address. I also have control of some vanity address private key on my computer such as 1Bit, 1Face and many others.

Probably more than 1000. It's suggested that you use different address for every transaction. Even you have big BTC in one of your addresses, when you use it change is coming to your newly generated change address. That's for security purpose.

I think it must be around 3000 now. And yes, the previous posters are right. You should not reuse addresses. Better have them unique for one transaction.

The simplest reason is... why would you let everyone look into your wallet and let them know everything you dealt with, where you are invested, that you gambled or tipped cammodels on a sex site? But if your addresses can be connected then you reveal more infos about you than you would wish.

The risk still is there when you not reuse addresses, for example with change addresses since when you send a payment and you send from 2 input addresses than those 2 addresses are connected too, together with all transactions these two addresses had.

One has to think about that carefully.

I don't think it is strange at all, people are used to thinking in account number or "payment destination" terms.

Indeed if you think about the invoice number example, whilst the invoice number is unique to the request for payment, it is not where you send the payment, that is the account number.  And really the Bitcoin address does work more like an account number since you can send several payments to the same address and they go to the same "destination".

Thinking further if one were to be paid one's monthly salary in Bitcoin, who would that work in practice in the new address fo every transaction model?  Do you need to give your employer a new address every month?  And they need to re-schedule the payment run every month?
