Private Key Hacked by brute force

We are working on this now.  We are devising an algorithm that exploits certain weaknesses to get to address keys.  More on this later. 

The scientific answer to your question is 'Yes'.  But it is challenging.

Oh, you mean it was a brain-wallet address generated by a simple phrase.

With a properly generated private key?

No.

If there becomes 100 trillion wallets in use, do you think finding a wallet with a balance will become common?

100 trillion is a VERY small number.  The answer to your question is no.

Is the current private key secure enough to last 10,000+ years?

Assuming that no new weaknesses are discovered in the ECDSA, SHA256, and RIPEMD160 algorithms, the current private key is secure enough to last more than 14 billion years (note that the entire universe is probably less than 14 billion years old right now).

If weaknesses ARE discovered in any of those algorithms, then the algorithm can be replaced before weaknesses are discovered in any of the other two.

Is there a way to scale up the security of the generated private keys somehow if needed someday?

Yes, but it might require a hard fork.

100 trillion addresses = 10^14
All possible addresses about 10^48

10^48 / 10^14 = 10^34

Each time you generate a new address you have 1 in 10^34 to find any one of those 100 trillion addresses

Fill Your Barrel with Bitcoins!
They have done the calculations and always shows it is more Profitable to mine BTC with the hashpower than attempt to crack a wallet. Even generating new wallets hoping to find Bitcoins is less likely than mining a block. The chances are Ridiculous tiny (not in your lifetime).

I don't have my English to Nerd translator handy, butt is your query about the probability of bitcoin address collisions?

https://bitcointalksearch.org/topic/what-are-the-chances-of-an-address-collision-and-what-happens-when-it-does-104461 "What are the chances of an address collision? and what happens when it does?"




Did this actually happen to you? All your coins stored in one address? Or was the wallets password compromised?

So. Yes this has happened before.

Private keys cant get common at all .it has a specific algorithm and it has probability to zero .it is not a bug of bitcoins wallet .it generates at a high pace with accuracy because it is a machine .and the wallet can get hacked and i dont think u can get it back because its untraceable .

I don't think you understand my questions. And looking for a non-newbie to answer them. (No offense)
