You don't need any space to store all of the private keys. Check out directory.io. You can find all of the private keys listed there.
In fact I even do not need directory.io
I already have all private keys.
For example the key number 0xc4bbcb1fbec99d65bf59d85c8cb62ee2db963f0fe106f483d9afa73bd4e39a8a in my collection (I really like hex counting by the way) is 5KJvsngHeMpm884wtkJNzQGaCErckhHJBGFsvd3VyK5qMZXj3hS
You may ask me about any key - I will tell you it for free
Just give me its order in my list Smiley

How many are possible BTC addresses that can be generated ? How many GB space need for all of them ?
there are 2160 addresses which start with '1'
You have to have ~ 2135 GB to store all their privkeys

you can't do it without fees, too many inputs, never will be confirmed

The probability across a address by another one is very very low

So is the probability of all the air molecules spontaneously collecting together in one corner of the room and suffocating everyone in the room.

but i don't feel safe

Then you should study more maths.

it could be with more address possible?

No.

BTC foundation team could change that ?

No. That would be a waste of time and effort right now.



You want to say probability of someone hack me by account number and password on a bank is more than 6 billion men across me on BTcs addressees ?

For those still worrying about having an address collision, I think they simply don't get how incredibly low the chance is.

Is it possible for one to be struck by lightning 10 times tomorrow? Theoretically yes.
Should one be worried about that? I won't.

Can anyone tell me that out of 2^160 addresses possible...
How much is 2^160 in a linear format? Or how many quadrillions are there? Are you competing in addresses mining using reverse asics to get some speed?
According to wolfram alpha...http://www.wolframalpha.com/input/?i=2%5E160&dataset=

I think that'll need to wait until the heat death of the universe before we'll have a collision.
still far away from being impossible,

You and I have a very different definition of the word "impossible".

it could happen one day,

No.  As long as the addresses are properly generated, it can't.

this is why it's better to split bitcoin(big amount) in to multiple address

If we assume for the sake of argument that you are correct about there being a chance that it could happen, wouldn't you be increasing the likelihood that someone will collide with one of your addresses if you split your money up into multiple addresses?  If you split up you money into 10 addresses, wouldn't that mean that you are ten times more likely to lose some of it?

BTC Addresses in use now are around 200-250.000. Number of BTC addresses are increased so much in confront of the last year. Next year we will see something of very good Smiley

I think around 1/4 are owned by exchanges/gambling sites.

Warning about what?
I meant Blockchain.info and similar shows the number of used address, isn't it misleading as it isn't accurate? or is it accurate? Huh

I assume you are talking about this chart:
https://blockchain.info/charts/n-unique-addresses

In that case, when blockchain.info reports "unique bitcoin addresses used", they are talking about addresses that have received bitcoins on that day.  It is quite easy to count the addresses that receive bitcoins.  What is impossible is to know how many new addresses were generated which haven't received any bitcoins at those new addresses yet.

Why would it matter whether or not you can count the generated but unused bitcoin addresses?
I don't think I can count unused address, I mentioned about used addresses and amount shown in websites. Smiley

It all depends on what you mean by "used addresses".  In my comment that you replied to, I made it clear that I was talking about addresses that had not yet received bitcoins:

Additionally, its impossible to know how many bitcoin addresses have been created, but which haven't yet received any bitcoins.

You replied to this stating that "counting used bitcoin addresses is impossible".

So basically, counting used bitcoin addresses is near to impossible, so why doesn't Blockchain.info and similar doesn't show any warning/messages about this? Huh

That would imply that when you say "used bitcoin addresses", you are talking about bitcoin addresses that have been created, but which haven't yet received any bitcoins.


If you want to know how many unique addresses have received bitcoins that are confirmed in the blockchain, that can be counted and known.

If you want to know how many unique addresses have been generated in peoples wallets, that cannot be counted or known.
