It is not hard to find a wallet(the bitcoin address) with enormous amount of money in it.
Its not hard to find a network with enormous amount of hashing power(any pool).
Bitcoin ASICs can't generate private key / address pairs. They can only mine blocks.
So my question is; How safe is it realy? How long time would it take for a big pool to break a singel address and can it be done?
Like I said, pools with their ASICs can't "break" addresses. And even if they could, it would take far longer than it takes the sun to burn out and die. The address space is simply that large.
