Looking at this graph/data from blockchain.info:

https://blockchain.info/charts/n-unique-addresses

How can only 600k unique addresses be the total ever  to have appeared on the block chain? (  I would understand if this was a graph of unique addresses in the past 24 or 48 hours or some period Like that -  but not unique addresses that have ever appeared on the blockchain?? )

(Also why would this number / chart line ever dip down , i.e. Look at a 30 or 60day graph- shouldn't it always be increasing or at minimum staying the same from day to day?)

 I guess what is also confusing to me, is that the only way to get bitcoins into an address is to perform a transaction (short of mining a block) , so 600,000 unique addresses (total , ever)   Divided by $40 billion (about @ 2300$ Per btc) total value of all outstanding bitcoins equals an average address value of around $61,000 ???

 I'm just so confused by this graph and was hoping someone could shed some light -  wouldn't this also mean that less than 600,000 people worldwide have ever done a btc transaction ( because one person could of course have multiple addresses, but even if everyone only had one address it would mean only 600,000 addresses have actually been used in a valid transaction- right?)

Thanks!

Edit: maybe this means unique IP addresses ?  ( if so I really think blockchain.info should specify this, either at the top of the graph or on their "charts" page where they give a bit of a description for each graph/data set)

Also, why is their only one unique address for the first and second day, and zero for the third through sixth?
Didn't Satoshi use a bunch of different addresses?

Maybe it's the amount of unique adresses generated each day/used by the users?

I assume it is per day.

There currently 300 k transactions per day. If the typical transaction sends bitcoins to a new address plus a new change address, then 600 k new addresses per day seems reasonable.

yeah I thought this too

This does make sense and add up.   Maybe we should just chalk this up to an oversight/typo in the graphs actual  title/description. As all the other graphs ( that have a specific time frame for the data points) , clearly state it - in  the description and/or title (i.e. X number of Y  per second  or per day  ect..)..

The site clearly states that : "The total number of unique addresses used on the Bitcoin blockchain."
This means that the graph shows the number of different bitcoin addresses used on that day/month/....
Also, if it would have been all the addresses ever, then it is impossible for the graph to decrease before with each transaction it would have just got higher.

It does make sense... Please explain why it doesn't make sense?

I have reached to some older data about number of addresses which appears in the blockchain:

"As of 12th May 2013 there have been just over 13 million distinct Bitcoin addresses which have been recipients of funds, and of those just over 1.6 million carry a positive balance."

That blockchain stat page is showing number of unique dresses used and stored in blockchain DAILY.

in 10/01/2009 6.571 addresses were used and in 2 days later only 30 addresses, so one week after genesis block Satoshi created more than 6k addy and after that 30 and 70 and 100 and so on.
Also I can't find any dates before 10/01/2009 why is that? what the hell were Satoshi doing during that 7 days?
Also why they are all created in 3:30 or 4:30 what is so special about that time frame?

Maybe he was working in real life, so he didn't have much time and decided just to spend 1 hour with Bitcoin everyday? :D

Whats the current number?

Consist of 35 different characters lower case and upper case of letter and combined with numbers if you ask me that is an incredible amount of combinations more than billions unique wallet addresses cam be made satoshi made it that way so that if you entered the wrong address and send some btc in there you won't have a problem taking back your money cause it won't be send even if you have type it correct but the last uppercase letter was lower case cheers to that so genius.

For anyone who comes across this in the future, I reached out to blockchain.com (which was blockchain.info) and they tell me that it is indeed the number of unique addresses used during that day for either sending or receiving. They also told me they'd update it.. but haven't yet and it's a couple months later.. someone else want to poke them?

don't get your hopes up. blockchain team is one of the laziest ones in the world when it comes to changing or updating their platforms even when it comes to correcting the bugs in their platform including their wallet! there currently are a ton of issues that have existed for nearly as long as the site existed and they are well aware of them and yet don't move a finger correcting them.
