Technically you should be using a new Bitcoin address for every single transaction you make!

[DannyHamilton]

If you are using Bitcoin Core then you already have more than 100 bitcoin addresses. You just aren't aware of it.

Bitcoin Core creates 100 addresses that it doesn't tell you about when you run it for the first time.  It then uses a new one of these hidden addresses for the change from your transactions every time you send a transaction.

I have a few Bitcoin Core wallets, so I have a few hundred addresses.

Then, it was recommended by Satoshi Nakamoto that you use a new receiving address for EVERY transaction.  I've done over a hundred transactions, so I have over a hundred receiving addresses.

I've also installed a few other wallets either to try them out or for specific purposes (such as MultiBit, blockchain.info, Mycellium, etc).

I've never counted, but if I had to guess I'd assume that I therefore have somewhere around 1,000 addresses.

For the average user you probably only need a handful, though people may want to use more if they're trying to remain anonyomous. I only have a few so far but have just used the one currently to recieve money.

[blatchcorn]

Wow how do so many people have 50+ addresses?  Surely they cannot be actively using them

[Remember remember the 5th of November]

Around 200,000. Don't ask why, I was rather naive 3 years ago when I did it. That wallet has a size of over 100 megabytes, so most likely much less than 200k, my other wallet is over 10 megabytes so it has a few Ks of addresses there.

Well, if i do that. I would have >200 address now

I think it's hard to me, to use 1000 address

Yeah, you're right

I have 2 at present one for saving and other for gambling

[Polycoin]

I have 127,000,000 Bitcoin addresses.

You have some serious privacy issues there!
One address for saving will make anyone who trades with you aware of your bitcoin fortune!

[BurtW]

The question really should be two parts:

1) How many active addresses do you have (addresses with unspent transaction outputs)?

2) How many total addresses have you used?

Everyone should use a different address for every single receive transaction and every change address should be different.  So the answer for the average user should be:

1) 50-100
2) thousands and thousands

Any other answer is bad for the long term viability of Bitcoin, and should be highly discouraged.

If you care about Bitcoin please switch to a wallet which will naturally lead to the correct user behavior and away from wallets that do not.

Good:  bitcoin-qt
Better:  deterministic wallets (Trezor, wallet32, etc.)
Very bad:  blockchain.info using its default behavior

Also, all donation addresses should be handing out a new address to each visitor and all periodic payments should use deterministic key pair generation.  Any use of a static address, whether vanity or not, should not be done and should be hightly discouraged by the entire user base (don't use them, ask for a different address every time when making a payment).

Reason is in my signature.

This behavior is bad not only for your privacy but the privacy of everyone who does transactions with you.  If you (and others in your boat) care at all about the long term viability of Bitcoin you will stop it at once.

[Kayex]

I have an address for every single transaction J do.
I care about anonymity

[BitcoinBarrel]

I have 127,000,000 Bitcoin addresses.

But only a fraction of private keys 

[risk91]

i just have 10k bit coin address...
because that's i need...

and i've a plan to create 1 million address..

[5 Guys Burgers]

i only have 1. do we need more than 1 really? i mean why be paranoid idk.

[dserrano5]

i'm confuse if i must to take care a lot of addresses..

You don't have to take care. You only have to give a new address everytime you are going to receive a payment, and use a wallet that sends change to a new address everytime you make a payment.
