Number of BTC Addresses in use now

[Amph]

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, it could happen one day, this is why it's better to split bitcoin(big amount) in to multiple address

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?

I have used around 100-110 address till now 

[amaclin]

Till today, I might have surely used a minimum of 150 addresses.

Wanna buy your bitcoin private keys which you not need anymore

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.

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

The probability across a address by another one is very very low but i don't feel safe .... it could be with more address possible ? BTC foundation team could change that ?

[DannyHamilton]

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 ?

Another question i want to make 1000 BTCs addressees and send my Bitcoins to them equally for more security . How can i do it without fee and fast ?

you're looking at this http://bitcoin.stackexchange.com/questions/13442/how-to-do-mass-payouts-in-my-application-to-multiple-addresses-at-once-or-very

but i think there are program that let you do this even faster

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

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
