So you bought this account just recently?
No way you could have been a bitcointalk member for 2 years without ever reading this frequently (asked/answered) question.

The risk is non-zero, but small enough that you don't need to bother (unless you're using software with a broken random number generator). If you bother about duplicate private keys, you should bother more about the possibility of being eaten alive by an ice bear or drowning in a soup bowl - both events are much more likely.

After I made a paper wallet for long-term saving,
I start thinking about posibility that somone can create same priv. key
in their wallet in the future.

I know that posibility for this is very small, but it exist.
If someone want to create billions and billions private keys,
he can generate someone address with positive balance.

What you people think about that? This can become a big problem
for Bitcoin in the future... no?

I am a little scared  Huh



im thinking of that too, in the future it is possible to generate private keys for used address but when i knew the total possible address im thinking im could be dead if that thing happens. i've read somewhere in this forum than all possible address is greater than the number of dust in the world

it was already said multiple times that collision probability is so slim that it is more feasible for the universe to explode right now instead

anyway by splitting your balance among several addresses, you can prevent that you lose a big portion of it in the unlikely event that an unimaginable collision will come out...
