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

A collision with any of the SHA algorithms has never been recorded. There are more possible private keys than there are grains of sand on every beach in the world. Don't be scared. Just keep you keys safe. The only theoretical issue is when quantum computing becomes a reality. But this is many, many years in the future.
