I didn't meant for a single Address
I meant he generate all the private keys which are possible and then search them using the addresses .
Isn't that correct

It has already been done here: http://directory.io

I think this basically answers OP's questions. Just look at that database and the ridiculous number of pages (904625697166532776746648320380374280100293470930272690489102837043110636675). Do you think it would be easy to search for a certain address that you want to hack in that big database? No. I think it would take years or even decades before you can even hack a Bitcoin address using that database unless you got lucky and found the address that you were looking for at the top part of that list.

Maybe if someone designs a killer searching algorithm that will let you go through that much number in such short period of time, then we're all doomed.

Yup that's what i said it is not impossible to get Public key of a wallet you don't own.
What if someone got lucky and went onto a page and found a public key with 100+ BTC on it  Shocked
Then i think the owner of that address will think that Bitcoin addresses can get hacked and their trust from the system might fade away.
Am i wrong ?

This question is arising in my mind after i did some research.
What will happen if someone brute Force Private keys in Base58 Format ?

And he succeeds then I think he will get admin access to all the wallets and can ruin the Bitcoin.
I know it's very hard to go through the database but It's not impossible either.

Tell me what you guys think about this.

Let's consider for a moment that the FBI, NSA and all powerful government agencies has a lot of computing power and are able to bruteforce passwords made of very strong encryption. No matter how much computing power these agencies have, they cannot bruteforce more than a few private keys and for this they will take maybe 20-50 years on an optimistic note. Because private keys are random combination it is very very hard to bruteforce them.

So in the end I can say 100% sure that for the moment we are very safe from this point of view, who knows what happens in the future.

what do you mean by brute force?

if you think someone can find private key from public key then it is impossible.

but if you are thinking about brute forcing an encrypted private key, then it depends on the encryption method that was used and the password used for that encryption so it can be possible or impossible depending on what I said.

I meant he generate all the private keys which are possible and then search them using the addresses .
Isn't that correct

it is possible but it takes until the end of time to generate a small portion of total private keys.

I found this article directory.io is fake. https://m.reddit.com/r/Bitcoin/comments/1ruk0z/dont_panic_directoryio_thing_is_fake/ . Is this true?.

it would not be wrong to say that a thing is impossible if or anyone we want to do .
so there is risk which can be done by  stealing data to loss our money .

I think accessing private keys of all bitcoin address is quite impossible as to access private key of even one bitcoin address will take lots of computing power and very long time may be even a lifetime period. There is some fear regarding supercomputers and quantum computers which are still a dream and yet to find actual working prototype so i don't think this is possible and will be possible even for next decades.

That will not happen from night to day, we will see it coming with years or even decades in advance, things can be changed for when such event to occur.
