I honestly don't know if you are trolling or just stupid.

You asked a question, I answered it.

Simpler version: NO.

There IS that possibillity right? So IT will happen at least once in the next 10 years where a high value address is attacked and stolen?

Someone will win the lottery.

Is this just as much luck as solo mining? I may get lucky and get a private key to a high value address?

LOL, I can generate a 1mtgox address every second, I can collect millions. I'm asking what IF they end up using an address that I have the private ley to? There is no protection is there? So someone somewhere can get lucky and get a private key?

Yes someone could also get "lucky" and win the lottery .... a dozen times ...  in a row.  That would be more likely than brute forcing a private key.

3. It may take months, quadrillions of years but why can't I vanitygen (thought its not really vanity) mtgox's green address or any high value address? Then empty it?

I would purchase 9x 6990s planetary sized super computers consisting of quadrillions of chips each a quadrillion times more powerful than all computers today combined, what stops me?

FYPFY.

Under that scenario the heat death of the universe would stop you, and long before you even had a 1% chance of brute forcing an address.


Slightly less snark answer is that addresses are deceptively short looking.  2^160 is a very large number.  It is larger than the amount of atoms in our universe.  You have no plausible chance of brute forcing an address.

I don't understand this. I am generating addresses using vanitygen and here are the scenarios:

1. I generate many 1mtgox addresses. I have the private keys, what if one day mtgox uses an address i have? What stops me from spending all their coins since i already have the private key?

2. Can private keys somehow be different for the same address and the correct one can be checked against the blockchain?

3. It may take months, but why can't I vanitygen (thought its not really vanity) mtgox's green address or any high value address? Then empty it?

I would purchase 9x 6990s to do this, what stops me?
